Aorus p850w review in Spanish (complete analysis)

Although Gigabyte was always a player in the power supply market, it was not until a few months ago that its high-end gaming product brand, AORUS, fully delved into this Aorus P850W that we will discuss today.

Will it meet expectations? Let's see it!

We are grateful to Aorus for the trust placed in ceding this product for their review.

Aorus P850W Technical Specifications

External analysis

The front of the box shows the Aorus font in all its glory, and reminds us of some important features.

Let's break down in more detail all the features that Aorus announces for this power supply:

• 100% modular wiring, something totally expected in a source of this level. 100% Japanese capacitors: again, it is normal to use them due to their known reliability, although it will remain to be seen in the internal analysis if this is the case and if good quality series are used. Fan with double ball bearings and a semi-passive mode of intelligent control. The source keeps the fan off at low loads, and turns it on when needed. Other sources with this mode make use of fans with hydraulic bearings or the like, which suffer much more in the on and off phase than ball bearings. AORUS made the right choice by using such a fan. Single 12V rail. Here AORUS joins the marketing that affirms that this implementation is the best, when it is not necessarily the case, and the truth is that the multirail is expensive to implement since in sources of this range it provides protection characteristics. The brand says it's the best overclocking design, something that's less debatable. Efficiency 80 Plus Gold, with more than 90% efficiency on all loads of more than 20%, and a peak of 93% efficiency, all with the European 230V power grid. You can learn more about this certification and what it means in this article on our forum. 10 year manufacturer warranty, an extremely generous period, on par with most brands and above some others. Peace of mind in the event of a faulty source and AORUS confidence in the quality of this new range.

Once we open the packaging we find more than correct protection inside, which assures us that it will come safely to our home. All the wiring is in a nice bag that gives us a great premium feeling.

All cables are flat and do not use the meshing that is usually seen for this price range. There are supporters and detractors of this type of wiring, the truth is that we like both types, but it is noteworthy that in this case we have taken a good taste in their mouth, being thin, versatile and manageable.

What we do not like so much is that the ATX cable is also flat, since it is divided into many strips of different sizes and makes their management quite messy. If we see it from another perspective, it is also true that it is appreciated that the cable is not as fat as in the case of meshes, facilitating a clean assembly in boxes that do not leave much space to manage it.

We also find capacitors in the ATX, CPU and PCIe cables. This is something that many companies do to improve the electrical output of the source, although in the vast majority of cases they are not really necessary. We usually penalize them, but in this case we have not seen that they are annoying as it happens in other models. It also gives the appearance that the joint can be broken very easily, but we have seen that this is not the case.

Next we will talk about the number of cables offered. Now it's time to take a look at the source.

The external aesthetics of the new AORUS font is somewhat curious, where black and gray are combined, in addition to the brand's characteristic orange. We think it gives it a very personal touch, although unfortunately we have to say that the ends of the stickers come off very easily.

On the front side, we find a sticker that warns us that the fan will remain off at low loads, and it is important to warn of this since there may be users who think that the fan does not work;).

We continue to the modular board part, and here it is time to talk about cable management again. First of all, it's worth mentioning that unless you mix modular cables from other power supplies, there are no connector compatibility issues.

The number of connectors offered is as follows: 2 EPS (CPU) connectors, 6 6 + 2-pin PCIe connectors, 6 SATA, 5 Molex and 2 Floppy.

Be careful, because there is a small 'trick', and that is that for EPS and PCIe ( which are connected in the same type of socket on the modular board ) we have a total of 6 cables, while the modular part of the source only It has 5 connectors. That is, we can only use a total of 5 PCIe and 2 EPS, or 6 PCIe and 1 EPS.

A priori, it is not something that sounds precisely good. However, if we think about it, this is a reasonable decision since 6 PCIe and 2 EPS could correspond to 6 GTX 1080 or 3 GTX 1080Ti / RTX 2080 / RTX 2080 Ti and 1 CPU like the Threadripper 2990WX. That is, a Hardware configuration that surely exceeds 850W from this source.

A very possible combination would be 2 RTX 2080/2080 Ti with 4 PCIe, 1 Threadripper / i9 CPU with 2 EPS, and 1 additional PCIe connector for the motherboard (since it is normal for high-end models to include it). This configuration could be used perfectly:), so we have a ready source for high-performance multi-GPU configurations and HEDT platforms.

Of course, a source prepared for high-performance PCs only if quality components are housed inside, so it's time to take a look inside. Here we go!

Internal analisis

When opening this power supply we find that its manufacturer is 'MEIC', a Chinese company for which we do not have many references unfortunately. However, a modern internal platform can be observed by using the LLC technologies on the primary side and DC-DC on the secondary, which as we always say are the best that can be found in this price range.

The input filtering includes 2 X capacitors and 2 Y capacitors, plus 2 coils or chokes. These components help reduce electromagnetic interference and noise from household current.

In addition to this, we have protection characteristics in this filter thanks to the varistor or MOV that helps reduce and mitigate overvoltages. We also have a combination of NTC thermistor and relay to prevent current surges occurring at power on from affecting source components.

Moving over to the primary capacitors, we see two 390uF Nippon Chemi-Con (Japanese), making a combined 780uF capacity that's great for a source of this capacity and range.

On the secondary side, the capacitors are still Japanese and belong to Nippon Chemi-Con, with good series like KZE and KY, and various solid capacitors are also used, extremely high durability.

Here we also see which the chip in charge of supervising the protections, a Weltrend WT7527A that, curiously, has support for 12V overcurrent protection (OCP), a feature used in multi-rail sources and that could have been implemented in this Aorus despite be 1 single 12V rail. We do not know if it has been so, in any case it would be an excellent implementation.

To finish, the fan used is the Yacht Loon D14BH-12. As we indicated before, it makes use of double ball bearings that are quite suitable for use with semi-passive modes. This is a very durable type of bearing , although generally not as quiet as dynamic fluid and the like.

Test bench and performance tests

We have carried out tests to regulate the voltages, consumption and speed of the fan. To do this, we have been helped by the following team:

TESTING BENCH
Processor:	Intel Core i5-4690K
Base plate:	Asus Maximus VII HERO.
Memory:	16GB DDR3
Heatsink	Cooler Master Hyper 212 EVO
HDD	Samsung 850 EVO SSD. Seagate Barracuda HDD
Graphic card	Sapphire R9 380X
Power supply	Antec HCG Gold 650W

The measurement of voltages is real, since it is not extracted from Software but from a UNI-T UT210E multimeter. For consumption we have a Brennenstuhl meter and a laser tachometer for fan speed.

Test scenarios

The tests are divided into several scenarios, in order from lowest to highest consumption.

	CPU load	GPU charging	Actual consumption (approx)
Scenario 1	None (at rest)	~ 70W
Scenario 2	Prime95	None	~ 160W
Scenario 3	None	FurMark	~ 285W
Scenario 4	Prime95	FurMark	~ 340W

To measure the fan speed, an initial scenario is added that is measured just when the equipment is turned on, while the rest of the scenarios are measured after 30min of use (2h in the case of Scenario 1)

Keep in mind that due to the variable nature of these tests, since it is difficult to guarantee that very disparate tests over time are carried out under the same conditions, we always make comparisons with sources tested the same day, so that tests such as the consumption test can vary between different reviews.

Voltages and consumption

Fan control

AORUS has entered the PSU market with a satisfactory product in terms of quality and performance.

In external aspects, apart from the differentiating aesthetics of the source, the use of flat wiring stands out, which has given us a very good result, with additional capacitors for its filtering that, surprisingly, are not annoying as it happens in other sources feeding

As we also indicated, we found it disappointing that not all of the included CPU and PCIe connectors can be used, but upon reflection we believe that this is not a major disadvantage as there are still enough to squeeze the most out of the 850W from this source.

Internally, there are no disappointments, since the manufacturer MEIC has implemented all the technologies that are usually found in this price range, including a good range of protections and excellent quality components. Regarding its construction, there is little to complain about compared to its competitors.

To control the semi-passive mode, Gigabyte took the correct path, making use of a double ball bearing fan that does not suffer as much on and off as it does with other types of fans. The only thing missing is that it cannot be disabled, since many users prefer not to use it. When the fan is off, there is no noise. If it turns on, it is reasonably quiet, so we can speak of a good loudness on this power supply.

We recommend reading our updated guide on the best sources on the market.

The recommended price of this power supply is around 140 euros. This is a high price considering the fierce competition that exists in this market, since for 10 or 20 euros less you will find alternatives of the same power and similar characteristics.

We believe that the price is the most important point of improvement, since for the other aspects we have found a very good quality power supply. In many cases, it can be a highly recommended purchase.
