▷ Best power supplies on the market for pc 【2020】?

Power supplies are the most important component of our computer. ¿Why is it so important? Simply because it is the one in charge of giving energy to all our components. A bad power supply can degrade, burn or not support a voltage spike that will break one or more components of our computer.

So when we see many youtubers use power supplies of 30 euros to mount equipment with graphics cards with a high TDP we throw our hands to the head. If you are looking for a good power source, we have prepared this guide and if you have any doubts, we will advise you.

What is a power supply or PSU and what is it for?

The power supply can be basically defined as a component in charge of transforming and rectifying the 115 / 230V alternating current from the home to various direct current outlets at low voltages. These outputs are those that supply the electrical energy needs of the equipment components. For this reason, the fountain is one of the most important components to consider, as it is the true “heart” of the team that “pumps blood” to all the pieces.

It is essential to choose a power supply that meets several factors: it must have sufficient power to meet the needs of our components, in a format that fits in our box, that is of good quality, that has the necessary connectors, among other things.. Throughout this guide we will clarify each of these concepts briefly, and we will give you a list of recommended models for you to make the best decision.

How to choose the right font

How much money to spend

Since we are in a buying guide, the first question that must be solved is how much money it is necessary to spend on the power supply in order to obtain a quality model according to our team. The truth is that you always have to invest an adequate amount in such an important component, and we are talking in all cases of at least 40 euros. The following recommendation “scale” could be established according to the team:

• We recommend investing 40-60 euros in basic equipment with modest graphics or APUs where the budget is very tight, or to revive some old equipment. For mid-range PCs, that is, with CPUs such as an AMD Ryzen 5 or an Intel Core i5 and graphics of the GTX 1060 or RX 580 style, we recommend spending between 55 and 70 euros. For teams looking for high quality fonts, prepared to last, silent and that support more powerful graphics, we recommend exceeding 80 euros, or in the case of wanting all possible benefits, 100 to 120 euros. Finally, in high-end equipment high, high-end sources, although the truth is that it does not make much sense to go from 150 to 160 euros unless the total budget is really high, that is, a top-of-the-range equipment of (for example) more than 2, 500 euros.

These recommendations are very indicative, since each team is a world and the priorities depend on the user. In any case we believe that they are applicable to the majority of users.

They are also quite conservative, since investing more is never wrong. Throughout the guide we are sure that you will learn to choose the most appropriate one according to your components.

Required power

First of all it must be clarified that the power indicated by a source in its specifications is the maximum that it can deliver to the PC, it does not mean that this is its continuous consumption. Thus, if our equipment consumes a maximum of 400W at full load, a source of more than 400W must be mounted. In this section we give you our recommendations.

Choosing the right power for our power supply is one of the key factors when making the purchase. There are a lot of myths around him, some of which we are going to unravel here, in addition to giving our power recommendation to the teams.

The 50% myth

There is a widespread myth that says that, to maximize efficiency and minimize consumption, we must choose the power in such a way that the source is at 50% load in high consumption uses. That is, if our team needs 400W in games or stress tests, we should buy an 800W source.

The truth is that this is an extreme simplification that in few or no cases is fulfilled. It is based on the erroneous premise that the peak efficiency of a source is always at 50% load, which is not the case, although it is usually found close (at 30 and 60%).

An example of an efficiency curve from 0 to 100% load in 10% jumps. Between 20 and 100% efficiency, the differences are not substantial.

Another mistake in this idea is that the use of the computer at rest is not taken into account. In some cases, less electricity will be paid for with a lower power source that is more efficient at idle, because below 20% of load the efficiency plummets in most sources, something that does not occur after that " peak of the 50% ”in which the efficiency differences are not as substantial. We refer to the graphics.

In conclusion, optimizing the energy costs of a PC is a complex process that in no way is limited to a simple multiplication by two and, moreover, in most cases involves irrelevant differences in cost, unless we speak of dozens of servers running 24/7, which is a departure from the purposes of this guide.

The main thing is the quality

The first key idea we want you to keep in mind is that when choosing a power source, quality is more important than power. That is, if we are facing a source of sufficient power for our PC and good quality, it is not convenient to choose a model with more power if its quality is inferior.

Generally, when we are talking about ranges below 80 euros, we should take this idea into account. For example, the quality jump from a Corsair VS650 to a CX550 (or even CX450) is quite large, and those extra 100Ws are most likely useless. If, on the other hand, we are talking about a high range, buying more power will simply mean spending more money, and it is unlikely that for the price of the higher power model there is another source of much higher quality with less power.

For the record, we are not associating power with quality. We simply say that, given the possibility of choosing a source of higher quality but less power, compared to another of lower quality but more power, it is not worth choosing the latter.

The more sources of information, the better the choice

The last key that we want to leave you in terms of potency is that you should not rely on a single source of information when choosing it (not even the table that we have made with recommendations, although we have been very informed about it to do it).

This means we do not recommend relying solely on, for example, the recommendation of the manufacturer of a graphics card (which is usually hyper-exaggerated, as manufacturers know that many people buy low-quality fonts), or the recommendation of a power, or consumption information from a single website.

In short, we recommend combining various sources of information, such as the following:

• • Reviews of graphics cards, such as those on our website, in which the consumption of the complete equipment is shown, normally when the graphics card is loaded, so we could add about 100 watts (which is a generous margin) to take into account the CPU consumption at full load. Consumption calculators, which are less reliable than actual data but serve as a guide. We especially like the Be Quiet !, more than the well-known Outervision (which use Cooler Master or Seasonic). Consumption data of the graphics cards exclusively, such as those of Cybenetics Powenetics. This source allows you to know very well the consumption peaks of GPUs.

GPU power recommendation (for configurations with 1 dedicated graphics)

Having said all this, we leave you with some tables with the power that we recommend depending on the graphics card that we are going to install. These recommendations would apply on computers with CPUs up to the Intel Core i9 9900K (or its successor) or the AMD Ryzen 9 3900X (or its successor). In the event that we are going to use processors with a very high TDP such as the Threadripper 2950WX or the i9 7920X, we could raise the recommendation by 50 or 100W in each case.

In the tables we show the recommended power for the source and in no case an estimate of the equipment consumption. Further:

1. They are recommendations that only apply to quality sources. In no case for false power models that are so popular in the market, they are totally indicative recommendations and subject to errors. If in doubt, we invite you to ask in the comments with your complete equipment and the source in question. They are a recommendation for configurations with 1 single graphics card, in no case with several.

We also recommend that the power chosen be "Loose" or "Overclock".

The case of AMD VEGA

In the Vega 56 and 64 graphics we have put an asterisk because this graphics card model is very peculiar in terms of energy consumption, due to the especially high consumption peaks that have been observed, and that even caused problems with sources like the Seasonic Focus Plus, whose models manufactured before 2018 have overly demanding overload protection and can jump with one of these graphics cards.

In this situation, many users decide to apply an 'undervolting' to their Vega 56/64 that drastically reduces consumption without affecting performance too much. Here, we could be quite sure that a quality 550W source would measure up (and that is that in principle it should be stocked as well, but it depends on the specific case, which is why we make this clarification).

The opposite is also the case, many users choose Vega 56 to get the most juice and "unlock" a performance similar to Vega 64. This implies an increase in consumption that makes us recommend a minimum source of 650 or 750W for those uses, and especially quality (see "high-end sources").

Efficiency and 80 Plus certification

The 80 Plus certification is one of the aspects that people tend to focus on the most. It is basically a multi-level certificate (Standard or White, Bronze, Silver, Gold, Platinum, Titanium) that is awarded to a source based on its level of efficiency.

Ultra simplified explanation of the concept of efficiency in power supplies

A power supply carries out a series of transformation and rectification processes from the high-voltage alternating current that we have in our homes to the low-voltage direct current used by our components.

During this process, there are a number of energy losses that, when the equipment demands a specific power from the source, it needs to expend even more power from the electrical network in order to deliver the demand to the equipment.

The power that is delivered to the equipment is OUTPUT and that which is expended from the electrical network is INPUT (PENTRAD> PSALID), and the efficiency is defined as the relationship between these two: EFFICIENCY = PSALIDE / PSALID, and Express with a percentage. For example, a source that to deliver 500W spends 600W from the wall, 500/600 = 0.8 then the efficiency is 80% at that specific load ( the efficiency depends on the load, that is, on the consumption of the equipment, you can see it 2 images below ).

80 Plus requirements for sources tested with a 115V mains voltage (this is how most are certified). It should be noted that THE EFFICIENCY OF A SOURCE VARIES ACCORDING TO LOAD, and its sweet spot is usually between 30 and 80% of load, while below 20% it collapses.

It is important to mention that 80 Plus does NOT do any quality or performance test of the source, it only certifies the efficiency, being simply one more aspect when it comes to talking about the quality of a source and in no case conclusive proof that it is a recommended source. There are 80 Plus Bronze fonts better protected, quieter and with better components than some 80 Plus Gold, for example.

In any case, for convenience, the different price or quality ranges are usually limited according to their 80 Plus certificate. It is common to talk about " for that team buy an 80 Plus Gold font " when in reality it means " for that team buy a medium-high range or higher font ". We prefer to avoid this generalization and we are cautious with the 80 Plus certificate.

Finally, it is worth mentioning that better efficiency implies less heat generation and a reduction in consumption that ends up affecting the electric bill. However, we believe that, beyond a Gold source, the differences in consumption are not significant, unless we are talking about dozens of servers running 24/7.

You can learn more about 80 Plus in our forum article.

Cybenetics

To end this section we talk about Cybenetics, the alternative to 80 Plus that takes a totally different approach when it comes to doing your tests and giving your certifications. From it we highlight the extensive reports they offer on the tested sources, where you can check their electrical performance, wiring, aspects such as the manufacturer or the fan they use, and in many cases even a list of all their internal components.

But undoubtedly what stands out most about this company are its LAMBDA loudness certifications, which allow us to easily know the level of silence of a source, and for those who are more interested, they also offer detailed noise level data in their reports.

Beware of low quality fonts and false specs!

When looking for a power source, and especially in price ranges below 100 euros, we find an authentic "minefield" in which a good part of the models are, despite the opinions of users indicate otherwise, low quality and false specifications. We strongly recommend researching and contrasting information from a wide variety of sites before purchasing.

What happens if I buy a poor quality font? The truth is that nothing has to happen. Many people use these fonts for years without problems, but many others suffer the consequences. At best, the font will fail soon (and after 2 years, there is no free replacement possible if you don't have any further warranty), but at worst it can cause components to stop working.

With guides like this, buying a low-quality font is absurd, since decent models often have similar prices, sometimes even lower. Why was someone going to buy a bad font then? Well, it is simply a problem of disinformation and how difficult it is to prove that a manufacturer is telling falsehoods.

Many believe that, although these sources have quality components, their specifications are real (super high powers of 700 or 900W at 50 euros, false 80 Plus Silver certificates or "85 Plus" that do not exist...), and therefore attractive options in terms of value for money. It is something that

In short, when a manufacturer offers a lot for very little, as the examples in the previous paragraph… Doubt and look for information on the Internet!

Which format to choose, is modular cabling required on power supplies?

You have this information broken down in detail in our articles:

Power supply formats

The main format of most power supplies is ATX, consisting of a chassis with a fixed width and height of 150x86mm and a length depending on the source, typically between 140 and 200mm. The choice of format depends on what your box supports, being for almost any semi-tower an ATX source. The story changes when we talk about towers of normal size but of pre-assembled teams, since many have their own formats. In these cases, there is usually no other option but to change the box.

When buying a high power ATX source, it is important to take into account its dimensions, because if it is very long (about 200mm) it may not fit many compact mid-tower units.

If, on the other hand, we are talking about small boxes or SFF “Small Form Factor”, most of them need an SFX font, while others still support ATX or ask for formats like TFX. Our recommendation is that you always try to choose an ATX source (it is absurd to mount an SFX in a normal box), and if you want a small equipment, the SFX format is preferable to the TFX since there is much more variety on the market.

Modular, semi-modular or fixed wiring

From left to right: Fixed, semi-modular, fully modular wiring source.

This is one of the most important external aspects, and it basically has to do with cable management. In a 'normal' source, all the wiring is soldered inside, so those cables that you do not need would remain in the box, since they cannot be removed from the source.

All this is solved with a modular wiring system in the power supplies. Basically, it consists in that in the back of the source no cables come out, but we find some connectors, in which we will connect only the cables we need, leaving the rest stored, for example, in the source box. As is evident, all modular sources bring the wiring with them.

Between both systems is the semi-modular system, which in order to save costs maintains as fixed cables those that are essential in any assembly (ATX and CPU, although sometimes the PCIe -which are sometimes expendable- are also fixed), while that "optional" wiring such as that for discs and peripherals is modular.

In general, modular sources are a good thing, for the improved cable management they offer. However, it almost always involves sacrificing quality and paying more, if we are talking about buying on a limited budget (much less than 100 euros). Our recommendation is that QUALITY should be prioritized over modularity since, after all, the impact of one or two cables remaining is not so great as to choose a medium or low level modular source, being able to opt for something better in the market.

Number of cables and connectors on power supplies

We also have a full article on this that you can read here.

Knowing the number of connectors that a source carries is essential when choosing it, since it must have enough for our team and for our expectations of updating. For this, we must consult our own requirements (especially the PCIe connectors of the graphics card that we are going to mount) and the specifications of the sources in particular.

To help with this purpose, we have made a table with the approximate number of connectors you should expect in a source according to their power.

	450W	550W	650W	750W	850W	1000W	1200W	Plus
CPU	one	one	twenty-one)	two
PCIe	two	4 (2)	4	6	8	8 or more
SATA	≥3	≥5	≥5	≥8	≥10	≥12
Molex	Indifferent to most PCs today
If we believe that a lower number of connectors is reasonable in low-cost sources (less than 80 euros), it appears in parentheses.

This table is not intended as a substitute for referring to the specifications of each source, but rather to see if a PSU has a number of connectors suitable for its power. This is very important since in the market we find nonsense as 1000W sources with 2 PCIe connectors, and when this occurs (with few exceptions such as the Corsair CX450 or some In Win sources) it is a sign that indicates that it is a source of false specs. (All this based on our experience in this regard)

Notably, we currently find two CPU connectors on the higher-end Socket AM4 and LGA1151 boards. We want to make it clear that it is NOT necessary to connect the two, either 8 + 4 pins or 8 + 8. With an 8-pin connector to spare.

Active, semi-passive or 100% passive ventilation

There are power supplies that have a semi-passive cooling mode. What does this mean? Well, the fan will stay off as long as it is not necessary to operate, that is, at low or medium loads. This is a system commonly present in upper-mid-range and higher sources, and can usually be activated or deactivated by the user using a switch on the source (in other cases it is not).

The advantages of the system are that, on paper, it offers a lower noise and increases the life of the fan. However, there are two major drawbacks: on the one hand, this is done at the expense of the temperature rise of the components inside the source. On the other hand, most semi-passive modes don't work too smartly so the fan can go into continuous on-off loops that reduce its lifespan. So:

• In low cost sources it is preferable not to use any semi-passive mode. Being less efficient than the high-end ones, they generate considerably more heat, so in practice the fan will work more aggressively than in an active source that has a relaxed control. In contrast, in sources such as those shown in the high-end section, they usually have semi-passive modes that, although they make them warm more, are not particularly worrying. However, most of these modes malfunction as they are prone to causing the fan to turn on and off a number of times which is detrimental to the fan.

Because of this, if you have a special interest in fonts with a well-designed semi-passive mode, we will mark them in the comparative tables of each price range with a “?? ️” if it has a good semi-passive mode, and just a "?" if it does not have this mode but, even so, it is practically inaudible at low loads (which is what interests us most).

Warranty period

Currently, it is very widespread among the recognized brands to give guarantee periods that are longer than the period of legal obligation by the European Union of two years. For this reason, we advise against buying any power supply with a 2-year warranty since any decent brand will offer at least 3 years on the products.

In basic sources, 3 or 5 years is more than reasonable, while in the mid-range and above it is recommended to buy one with a 5-year guarantee or more. There are brands with maximum quality products but guarantees that do not go up to 5 years, in any case whether it is sufficient or not is a user's choice.

There are, in fact, many sources with a 10 or 12 year warranty, a lifetime, but that are not necessarily better than others with 5 or even 3 years (we saw it in our review of the Sharkoon Silentstorm Cool Zero, which would appear in the guide as one of the best if it had a longer warranty period).

It should be noted that, in the first two years, the store is responsible for processing the guarantees, while after that the manufacturer is responsible. In most brands it is necessary to send the source to a European country (Germany or Holland normally) paying the shipping costs for one way, something to take into account since it could cost 15-30 euros.

The brand is not that important!

It is very common to see people talk that you only have to buy sources from a limited number of brands, or that if you buy from a certain brand, quality is guaranteed. The truth is that this is oversimplifying the matter. And is that almost all brands have models that, even being recognized by these "fanboys", are of a rather low quality.

What we should do is, instead, choose the best power supply in the price range in which we find ourselves, taking into account the quality, characteristics, performance and suitability of the specific model for our needs, leaving the brand as something secondary that we are simply interested in aspects such as RMA management or the warranty periods offered. And, in fact, most brands do not manufacture their products, or even design them internally.

Note: it is true that there are several brands that do not have any quality source for sale. These are easily identified by the large number of negative comments found in forums and which are usually quite well-founded.

In summary, choosing by model and not by brand is the smart option. We have compiled this list of recommended models thanks to objective and contrasted criteria and never guided by the particular brand.

Let's go with the recommendations!

Cheap power supplies (less than 50 euros)

In this range we can find very basic sources that are perfectly suitable for affordable gaming equipment, and for those office equipment or for other uses in which a quality source is sought.

Corsair CX450 and alternatives

Corsair CX450 - Power Supply (80 plus bronze, 450 watt, EU) 53, 99 EUR

The best source of these price ranges is the Corsair CX450, since its quality is at the same levels as the CX550, which costs about 15-20 euros more and which we will talk about later.

However, it has a 'tare' that most competitors do not share and that is that it only includes an 8-pin PCie connector. So we leave it up to the user to assess whether this sacrifice is worth it in exchange for higher quality.

The truth is that less and less graphics need 2 PCIe connectors, and if we do not plan to upgrade to an older model or a high-end one, it is most likely not necessary. (There is also the option to stretch to the CX550.) Of course, there are cases of graphics cards such as the RX 580 in which many assemblers bet on two 8-pin PCIe connectors (example: Sapphire) although one is sufficient (example: Gigabyte).

• High enough quality for its moderate price. 5 years warranty. Efficiency that dances between 80 Plus Bronze and 80 Plus Silver. Continuous and real power of 450W guaranteed at ambient temperatures of up to 40 degrees.

• Only one 6 + 2 pin PCIe connector, it should have 2!

There are several alternatives of the same level and price as the CX450 (somewhat worse, yes) with two PCIe connectors.

Alternative 1: Cooler Master Masterwatt 450W

Cooler Master MasterWatt 450 EU - Power Supplies 'Semi-Fanless Modular, 80 Plus Bronze, 450W' MPX-4501-AMAAB-EU Performant product; Quality mark.; Adequate performance EUR 63.50

This font is below the CX450 for quality, yet this one is pretty solid. It is semi modular and fortunately has two PCIe connectors. Its biggest negative point is the existence of a semi-passive mode that does not work very well and supposes an undesired increase in the operating temperature of the source. In sources of this level, semi-passive modes are not recommended.

Alternative 2: Be Quiet! System Power 9 400W

be quiet! System Power 9 Unit - Power supply (400 W, 200-240 V, 50 Hz, 4 A, Active, 103 W) Two independent 12 V rails for greater signal stability.; 80PLUS Bronze certified and up to 87% power conversion efficiency EUR 49.87

Very similar to the Masterwatt internally, as they share the manufacturer and most of the internal components. It earns points in the protection system and it does not have semi-passive mode, but it uses a worse quality fan.

Riotoro Builder 500W

Riotoro PR-BFX500-EU - Power supply, Color Black

• 80 Plus White Efficiency that reduces heat, noise and operating costs Flat cables to reduce clutter, improve installation and aid airflow Fully compatible with new Intel processors, AMD and their motherboards, and GPUs Thermally controlled 120mm fan for quiet low operation regular loads

Buy on Amazon

The Riotoro Builder is a true champion when it comes to value for money. Although this brand is very little known, its products knock down those of others that people tend to consider more reputable. This source has excellent references in terms of internal quality, and we could consider that it is located " between the VS and the CX of Corsair " to make a comparison with better-known models.

We strongly recommend its purchase when it is at a price of less than 40 euros, since it offers us a modern interior, with decent components, paying very little. Sadly, it can also be very expensive (above 50 euros).

• Superior quality to Corsair VS, and decent in every way. No especially negative point. When it is below 45 euros it is insurmountable compared to the alternatives of the same price.

• As always, by investing a little more there are much better sources, and in fact this Builder sometimes exceeds 50 euros. Low quality fan and CapXon primary capacitor.

Corsair VS450

Corsair VS450 - Power supply (450 Watts, Active PFC, 80 Plus) Color Black CP-9020170-EU

• 80 PLUS Efficiency: Runs without heating up and uses less energy than uncertified power supplies Black case, cable sleeves, and connectors: The touch of elegance your team needs without pocket pain Temperature-controlled 120mm fan: Maintains quiet operation with a wide range of loads

39.90 EUR Buy on Amazon

The Corsair VS range was recently renewed with new models, which can be identified by having a completely gray sticker. The old models, those with the orange sticker, did not enjoy a high quality but with the latest renovation we can speak of much more decent sources. However, due to its somewhat older internal design with group voltage regulation, we recommend the other alternatives in this guide. In any case, on tight budgets it can be an excellent option.

• Lower price than those shown here, 40 euros. Very good option for office equipment or ultra-low cost. The latest revision of Corsair VS (those with a gray sticker, not the ones with orange letters) has improved greatly.

• Outdated internal design, voltage regulation system not intended for current equipment. For only 10 euros more, there are much better sources, like all the options shown above. Low quality fan. We only recommend your purchase when there are no alternatives or it is very basic equipment.

In this price range, as it is to be understood, we continue to have to make important concessions in quality or benefits, as is the case in lower priced sources. Still, at this price level you can see very good quality sources prepared to support high-performance equipment, below we detail some of the best options.

109.79 EUR Buy on Amazon

The Bitfenix Formula is a range that stands out for three essential points: quality, protection and silence. In the first aspect it has an enviable internal quality, in the second with an excellent multi-rail system that offers 12V OCP protection, and in the third, a very relaxed fan control that makes it almost inaudible. In our review you can see everything about its benefits.

We specifically recommend the 650W model because it allows us to mount absolutely any Mono-GPU configuration on the market, even with the Vega 64 with high power consumption, without experiencing any problems due to possible consumption peaks ( to which the 550W model is more sensitive due to its distribution of rails, something that is not the case with “single-rail” sources )

• Very high internal quality, comparable to that of higher priced sources. Hyper-silent operation, it is a practically inaudible source. 5 years warranty. High efficiency. Being multi-rail offers a plus of protections. These rails are very well distributed in the 650W model so we can mount any Mono-GPU configuration and even some Multi-GPU.

• Non-modular cabling, which can be a very negative point for many users.

Corsair TX550M

Corsair TX550M - Power Supply (Semi Modular, 80 Plus Gold, 550 Watt, EU)

• 50 C operating temperature: can generate maximum power even at very high ambient temperatures 80 Plus Gold: works without heating and uses less energy than less efficient power supplies Semi-modular: allows the user to use only the cables they need for a look structure Cleaner with Better Air Flow 120mm Rifle Bearing Fan: Quieter than Cylinder Bearing but Longer Lifespan than Lined Bearing Japanese Capacitors - Unprecedented Reliability Even at Higher Ambient Temperatures

73.68 EUR Buy on Amazon

As an alternative option to the Formula we have the Corsair TX550M, a source that unlike the previous one is semi-modular, has a 2-year warranty, but all this in exchange for a lower loudness (it is noisier, enough for most users but not for the most demanding). Even so, in quality and protection they remain very even, so it is definitely a great option.

• 7-year warranty Very high internal quality Semi-modular cabling system

• Somewhat louder than normal source.

Other options one step below previous power supplies

Corsair CX550

Corsair CX550 - Power Supply (80 plus bronze, 550 watt, EU) 67, 73 EUR

This source, despite not reaching the quality levels of the previous ones, is an extremely balanced option since it is usually found at a good price in all stores and in stock, something that does not happen with the previous ones.

And it is that the Formula is worth 80 euros normally, the TX550M sometimes sees its price increased from 75 to 85 or even 90 euros… In contrast, the CX550 is almost always below 70 euros, being a great alternative to previous.

Riotoro Onyx 650W

Riotoro PR-BP0650-SM-EU - Power supply, Color Black Efficiency 80 Plus Bronze that reduces heat, noise and operating costs; Japanese capacitors for added confidence

The Onyx is a fairly unknown option, but still of very good quality, as you can see in our review. It is an excellent choice for users looking for modular cable management, and is comparable in quality to the CX.

Cooler Master Masterwatt 550W

Cooler Master MasterWatt 550 EU - Power supplies 'Semi-Fanless Modular, 80 Plus Bronze, 550W' MPX-5501-AMAAB-EU Power supply cooler master masterwatt 550 with 550w standard 80+ bronze 71, 18 EUR

This would be the last alternative we would consider, as all of the above are better, but it's still a good enough font to appear in the guide.

High-end power supplies (90 to 130 euros)

It is from this price range that we find the best balance point between quality, price and performance. Among the models listed here the internal quality is similar in all cases, and in fact very similar to higher priced models.

Now we show the most outstanding models in the range and other alternatives that do not have too much to envy and that also enjoy excellent quality.

Thermaltake Toughpower GF1 650W

Thermaltake Toughpower GF1 650W 80Plus Gold PC Power Supply

• All ripples are less than 30mV for high stability and extend the life of the power supply, regardless of 12V, 5V or 3.3V

107.19 EUR Buy on Amazon

The Toughpower GF1 is one of the most balanced sources we can find in this price range today. If we take into account that its 650W model is usually found below 100 euros, it remains one of the best options that can be considered, if not the best. In our review you can see its characteristics in more detail.

Basically, it is a range that does not have any notable weak point, and that leaves us satisfied in all aspects.

• 10 year warranty.One of the quietest fountains in its class along with the Corsair RMx range.It is the only range, together with the RMx, which we consider to have a well designed semi-passive mode.Well thought out and hassle free wiring capacitors

• The 750W version provides practically nothing compared to the 650W (this is a con for the 750 and a pro for the 650;)), while the 850W seems a bit expensive to us. We do not know if the price of 90-100 euros will remain or if it will rise substantially

Corsair RM650x

Corsair RMX Series RM650x 80 Plus Gold, Fully Modular ATX Power Supply, SATA, 650 W, Black

• 80 PLUS Gold efficiency certification for lower power consumption, less noise, and lower temperatures Optimized for virtually noise-free operation at full power Zero RPM fan mode for near-silent operation at low and medium loads Japanese 105 C capacitors Fully industrial category guarantees solid power and reliability Fully modular cables, so you only have to connect the ones your system needs

107.00 EUR Buy on Amazon

This is an alternative version to the Toughpower GF1 that maintains its quality levels, since internally they are very similar sources. The biggest changes are in the wiring and ventilation, we believe that the GF1 has a certain advantage in those aspects, however this is still an excellent option.

• 10 year warranty. One of the quietest fountains in its class along with the GF1. It is the only one, along with the GF1, which we consider to have a well-designed semi-passive mode. Internal quality and excellent protections.

• Rigid wiring is not a problem, just slightly more uncomfortable when mounting the PC. Semi-passive mode not deactivatable.

Digital monitoring on power supplies Is it recommended?

We have one more alternative, this is the version with monitoring of the RMx range, that is, the RMi, which also gains an extra protection thanks to the selectable multi-rail and a better quality fan.

Be Quiet! Straight Power 11 650W

be quiet! Straight Power 11 Unit - Power supply (650 W, 100-240 V, 720 W, 50-60 Hz, 8 A, Active)

• Power 650W High quality Model BN282

118.44 EUR Buy on Amazon

The Straight Power 11 is an option that stands out especially for its silence. And, thanks to its SilentWings 3 fan (one of the best that can be found in a fountain) and a very relaxed ventilation control, it is practically inaudible. The brand also boasts of putting a special effort in reducing the whine coil, although it is not something that we have been able to verify.

It also has a very extensive protection system thanks to a well-thought-out multi-rail design that offers us special peace of mind when faced with any problem.

As negative points, its 5-year warranty, clearly behind the competition. This is not because of quality, but because of Be Quiet's business decision to offer relatively low warranty periods, a clear mistake in our opinion.

• Absolute silence One of the best fans on the market One of the best protection systems on the market Modular cabling system designed in a very smart way, specially prepared to withstand a lot of current.

• Generally high price. 5 years warranty, less than the 7 or 10 that we are used to for this price.

Alternative power supply options

We finish by indicating here all those options that are also of very high quality and that deserve to be mentioned in the guide, but which we consider do not offer interesting attractive points (beyond, we say, great performance and great quality) compared to those that are highlighted above.

They are also options with which you will not go wrong, especially if they are found at a considerably lower price than the others.

Bonus track: do you want white wiring?

There is a very interesting market niche that is barely covered by manufacturers, and it is that of users who want their source to have white cables, to be aesthetically consistent with their PC. Currently there is only one option, and it is the Corsair RM750x White / RM850x White, which has the same cables as the normal version, only painted white.

Corsair HX750

Corsair HX750 - Power Supply (fully modular, 80 plus platinum, 750 watt, EU)

• 80 Plus Platinum: Runs without heating and uses less energy than less efficient power supplies Fully Modular: Allows user to use only the cables they need for a cleaner looking structure with better airflow 135mm FDB fan with noiseless mode: Virtually operating Quiet at Low Loads + 12V Rail Switch: Allows user to choose between a single + 12V rail or multiple + 12V rails

151.65 EUR Buy on Amazon

This power supply is basically an improved efficiency version (and without digital monitoring) of the RMi series. It has the 80 Plus Platinum certificate, being in the rest of aspects (even the internal platform) almost equal to the RMi. For this reason, we recommend your purchase in the case of a device with a very limited budget, since if you have to save you can go for the RMi series or even the RMx without losing too much quality.

We also recommend the HXi version (with software digital monitoring, like the RMi), and also the HX850 (with more power and connectors for MultiGPU configurations with Overclock)

And finally, the 1200W version has a very balanced price (around € 200) for its power level, and would be our star recommendation for, for example, Bitcoin mining.

Corsair HX1200 - Power Supply (Fully Modular, 80 Plus Platinum, 1200 Watt, EU) 235.00 EUR

• Super quiet operation with an aggressive semi-passive mode (and that works well), and a high quality FDB fan. 10 years warranty Possibility to choose between multi-rail and monorail for 12V. Is it recommended to leave it on a multi-rail for greater safety? Excellent internal quality. 80 Plus Platinum efficiency. High price but not exorbitant, unlike higher ranges.

• Rigid cabling will not be a problem, only slightly more uncomfortable when mounting the PC. Non-deactivatable semi-passive mode. Does not include too many improvements compared to the cheaper RMi range.

Enermax MaxTytan 750W

Enermax EMT750EWT Unit - Power supply (750 W, 100-240 V, 825 W, 47-63 Hz, 5-10 A, 100 W)

• DFR technology allows the fan to automatically remove dust from the fan blades Twister Bearing technology ensures efficient and quiet cooling continuously Up to 80% workload, the fan rotates at a constant speed of 550 rpm Comes with sleeve cables individual Sleemax offering protection and flexibility

Buy on Amazon

The Enermax MaxTytan is one of the most solid launches at this level of efficiency, and it is that to an extreme quality and an impeccable performance is added a well thought-out functionality, thanks to its wiring with “sleeving”, its semi-passive mode extremely aggressive (which makes it ultra-quiet), and added as a "Coolergenie" fan controller that can be connected to the PSU.

We believe this is one of the best sources that can be found on the market today.

A 1050W version is also available for multi-GPU configurations with overclocking and high demands. Unfortunately the 1250W model seems not to be present in the market at the moment.

Enermax EDT1050EWT Unit - Power supply (1050 W, 100-240 V, 1155 W, 47-63 Hz, 13-6 A, 100 W) Comes with Sleemax single-sleeve cables that offer protection and flexibility

• Extreme quality with an internal digital design (but without software monitoring, eye) Consumption meter integrated in the rear in the versions ofWired with a very well-thought-out “sleeving”: there is only one PCIe connector per cable so they support more overclock current 80 Plus Titanium efficiency Extremely quiet.

• It's a shame it doesn't have software or a selectable multi-rail system. The price is very high, but it's still cheaper than a fair amount of Titanium sources.

Seasonic Prime Titanium Fanless 600W

Seasonic SSR-600TL - Power Supply, Color Black Our Commitment to Superior Seasonic Quality; ATX 12V and complete modular 254, 21 EUR

This source is very special as it is a 100% passive model, and that despite its lack of a fan, it can deliver 600W of power with a whopping 12-year warranty. It is an excellent option for those who are mounting a PC with the fewest number of fans possible, although we believe that it does not compensate against other options, but in the end it is a personal decision.

• Efficiency 80 Plus Titanium Lack of fan (and coil whine? If any, we can always ask for a replacement) Excellent internal quality and faultless performance

• Extremely High Price Other sources of more power and less price will keep your fan off almost 100% of the time.

Corsair AX1600i

• 1600W Main Power: Provides 1600W 80 PLUS Titanium continuous power and ultra-stable Highlights: 100% Japanese high-tech, digitally designed 105C internal components achieve efficiency above 94% The only power PSU with Gallium Nitride Transistors: PFC gallium nitride (GaN) transistors in totem for superior efficiency in a smaller form factor Exceptional Electrical Performance: Incredibly stable voltages and ultra-low noise Software Supervision: CORSAIR LINK provides highly accurate monitoring software for PSU temperature, fan speed, voltages, AC / DC current power and efficiency

489.95 EUR Buy on Amazon

This is currently the best power supply in the world in the consumer market. No model on the market equals it in quality and performance.

The AX1600i is the first source to use transistors whose semiconductor is gallium nitride instead of silicon, being more efficient and compact. Added to this is a completely digital controlled interior (not only for the software monitoring it offers), with a manufacturer like Flextronics that obtains the best welding qualities on the market… So, internal quality? The best.

Regarding its power, 1600W is not the highest that we have seen in the market (for example, Super Flower sells a 2000W model), but we believe that it is sufficient for any team with such extreme needs and far from 99.9% of mortals. as to bring a source of more than 400 euros.

• Efficiency 80 Plus TitaniumExcellent quality that today has no precedent or competition in the consumer market. 100% digital control and complete software monitoring. Power and number of connectors that practically pose no limits to any extreme configuration.

• Stratospheric price, too high for 99.9% of mortals.

SFX Power Supplies

The SFX market is quite limited in terms of options, as expected. Still, there are models that enjoy excellent quality. We are listing them ordered by price from lowest to highest:

Silverstone ST30-SF V2.0

SilverStone SST-ST30SF v 2.0 - Strider SFX Series, PC 300W 80 Plus Bronze Power Supply, Low Loudness 120mm

• Partial Smart Fanless Operation (V1.0 only) Accepts standard SFX and ATX thanks to included Bracket 300W continuous output power at 40C operational temperature, suitable for continuous use (V2.0) Efficiency level 80 PLUS Bronze (82% ~ 85% efficiency at 20% ~ 100% load) First class Ralic with + 12V; Silent 80mm fan (V1.0); Silent 92mm fan (V2.0); Accepts single 6-pin connector; Active PFC

57.36 EUR Buy on Amazon

This is one of the most balanced SFX fonts when it comes to value for money. With a price that is usually around 50 euros, we get a quality pack, with good components, a fan with Duro bearings which is clearly above those seen in other competing sources, and ultimately an excellent option for any team Affordable you need a SFX font.

We highly recommend version 2.0 (not 1.0).

• Modern and good quality components at a reasonable price. Amazing durability and reasonably quiet fan. 3 years warranty.

• Power that may seem short on some computers, but NOT on most: sufficient even for GTX 1060. Not modular. The only PCIe connector it brings is only 6 pins, not 6 + 2, so some graphics could be incompatible even though they can be fed

An alternative that does have an 8- pin PCIe connection is the Silverstone ST45-SF V3.0 ( here we recommend ONLY version 3.0. Yes, it's a mess ), which unfortunately is usually at high prices, but if you find it cheap it is a great option.

SilverStone SST-ST45SF v 3.0 - Strider SFX Series, PC 450W 80 Plus Bronze Power Supply, Low Loudness 120mm Accepts standard SFX and ATX thanks to included Bracket; Efficiency level 80 PLUS Bronze (82% ~ 85% efficiency at 20% ~ 100% load) 67, 24 EUR

A step above we have the Corsair SF450 80 Plus Gold, where we take a quality leap to the extreme with some of the most cutting-edge components on the market, a 7-year warranty, maximum efficiency and modular cable management.

Its price is usually located below 80 euros, which makes it an extremely good option for mid-range and even medium-high equipment with graphics cards with moderate consumption (we could even mount an RX 590 or GTX 1080 without problems).

• Efficiency 80 Plus Gold. 7 years warranty. Maximum internal quality. Modular wiring management. Very quiet operation, in this case using a semi-passive mode.

• Very short wiring. This is so that it can be better organized in very small boxes, but in some cases it may require the use of extensions. Just find out if Corsair SFs cause wiring length issues in your box.

Corsair SF600 Platinum

Corsair SF600 - Power Supply (Fully Modular, 80 Plus Platinum, 600 W, EU)

• Compact SFX format - to supply power to the world's best small form factor computers 80 PLUS Platinum certification - for extremely efficient operation Zero RPM fan mode - near silent operation at low and medium loads Fully modular cables and individual sheath - to facilitate the creation of an amazing computer 92mm cooling fan - achieves low-noise operation even under demanding loads

119.90 EUR Buy on Amazon

At around 120 euros we have what is probably the best 600 / 650W SFX source on the market, a model that is updated with respect to the one we previously proposed to have 80 Plus Platinum efficiency. In addition, it is worth noting the inclusion of cables with sleeves which will maximize the "look" of the team.

It is important to mention that, although it brings an SFX to ATX adapter, the cables are intentionally short for use in compact format boxes. Not suitable for ATX semi-towers.

• Efficiency 80 Plus Platinum. 7 years warranty. Maximum internal quality. Modular cabling management with individually sleeved cables. Very quiet operation, in this case using a semi-passive mode. Includes SFX to ATX adapter.

• Very short wiring. This is so that it can be better organized in very small boxes, but in some cases it may require the use of extensions. Just find out if Corsair SFs cause wiring length issues in your box.

Corsair SF750

For SFF mounts that require especially high power, an interesting option is the sister of the Corsair SF600 Platinum, the SF750, which shares quality and features by adding more connectors and higher power.
