Silverstone et750

Silverstone is a brand with a great presence in the Hardware market, due to its extensive range of products: boxes, fans, refrigeration, accessories as varied as cables, disk housings, M.2 heatsinks… Today we analyze one of your most important bets. Recent in the power supply market, its Silverstone ET750-HG, belonging to its Strider Essential family with 750W of power, modular wiring and 80 Plus Gold certification.

Its promise is to offer a cheap, but highly efficient source, without great eccentricities and focusing on offering the basics for correct and safe operation. Will they deliver as promised? Let's see it. Let's start!

We thank Silverstone for trusting us with this source for analysis.

Technical characteristics Silverstone ET750-HG

External analysis

The front of the box shows us the source with its semi-modular wiring, and various benefits such as high efficiency, 24/7 operation, silent operation…

On the back, a little more information about the characteristics of the font. The warranty period is not mentioned here, but we have verified it and it is 3 years, a figure that is behind many competitors.

When opening the box we see a very good protection, with the source covered with a very effective foam. Essentials included, which is a user manual, modular wiring bag, hardware, and power cord. Let's go see the outside of the fountain.

The external appearance is not bombastic by any means, it is simple and sober. It is clear that working on a more attractive chassis, being a source that seeks to offer the best value for money, would be a total waste of money.

Much more important seems to us the use of good wiring. Absolutely all cables are flat, and we have no complaints about it, rather we like them a lot, since they are very flexible, although the ATX cable can be somewhat more messy with that format. Capacitors have not been included in any of them either, a very good news that will help the ease of mounting.

How many cables does Silverstone ET750-HG provide? Well, apart from the 24-pin ATX, we have: 1 connector for 4 + 4-pin CPU, which, given the capacity of the source, two should have been included for mounting on high-performance platforms such as X299 or X399; 4 PCIe connectors, more than adequate figure; 9 SATA and

We take a look at the semi-modular wiring panel, where only ATX and CPU cables are fixed, which are mandatory on any computer. The distribution of the connectors is simple, it leaves no room for doubt and it is not possible to make a mistake making the connections.

Let's take a look inside this Silverstone ET750-HG! First of all, remember that it is a process that voids the warranty and carries physical risks, since components such as capacitors can store high voltage loads even with the source disconnected. We do not recommend you to carry out this process.

Internal analisis

When opening this Silverstone ET750-HG, the internal design is quite familiar to us. Specifically, we have the Taiwanese CWT as a manufacturer again, with the internal platform called 'GPS', which we had previously seen with some minor modifications.

In this source, despite not being high-end, modern internal technologies are also used. The CWT GPS is LLC based on the primary side and DC-DC on the secondary side, two efficient systems that allow good control of voltages.

The primary filtering is made up of everything expected, with 4 Y capacitors and 2 X capacitors. In addition, an MOV offers protection against power surges, and an NTC + Relay protect the source from the current spikes that occur when we turn on the equipment.

We also see a GBU rectifier diode bridge, cooled by a heatsink and well dimensioned.

The primary capacitor is Japanese, a Nippon Chemi-Con KMQ from 400V to 470uF at 105ºC, of very good quality although with a capacity that does not seem too high for 750W.

On the secondary side, where the quality of capacitors matters the most because they are under increased stress, we have a mix of Chinese capacitors from CapXon, Su'Scon, Jun Fu, and ChengX.

In the case of electrolytic capacitors, even knowing the quality, its durability cannot be known with certainty, since it depends on how well they are cooled and the load they are subjected to, something that basically only the engineers who have developed know the fountain. For this reason, we believe that caution must be exercised in the face of capacitors from brands such as CapXon or Su'Scon, which are normally rated as mediocre in quality, but we are particularly concerned about the inclusion of Jun Fu and ChengX, which are of a very low level and questionable quality and durability.

Aside from electrolytic capacitors, we found several extremely reliable APAQ solid capacitors. We do not understand why this combination of high, medium and low quality capacitors.

The integrated circuit in charge of the protections is a basic Sitronix ST9S313-DAG, theoretically only in charge of the OVP although we do not know exactly. OCP protections are implemented only on 5V and 3.3V rails, on DC-DC converters, and OPP and OTP by other methods.

Considering the primary filtering, it gives us the impression that the protection system is not the best, but it is totally decent and safe.

On the back of the PCB, the solder quality is more than correct, a good job on the part of CWT, in which we have not found failures that could suggest an electrical risk or very fast wear.

We finish this internal analysis with the fan, a Loon D14SM-12 Yacht that uses Sleeve bearings, the simplest and least expensive, a drawback if we consider the 3-year warranty offered, since in case of failure we would not be covered for a period higher.

Voltage regulation

Consumption

Consumption is in line with that of other 80 + Gold sources, and the voltage regulation does not show any abnormal behavior.

Fan speed

Stage	Charge approx.	RPM
Scenario 0	<100W	~ 715rpm
Scenario 1	<100W	~ 715rpm
Scenario 2	<180W	~ 720rpm
Scenario 3	<300W	~ 730rpm
Scenario 4	<400W	~ 730rpm

The profile of the fan of this Silverstone ET750-HG is moderate, since it starts at around 715rpm, which are considered adjusted for a 120mm fan, but not so much for a 140mm one. Combined with the low-cost Sleeve bearing it uses, it leaves a source that can be audible from low loads for people who place special importance on silence.

For the most demanding users with silence, this is a problem. However, for those who do not have absolute silence requirements, we are facing a source that complies without problems.

In addition, this 'sleeve' fan has a motor with a clicking sound that can be heard if we only have the source on.

As the load increases, the fan profile is maintained and is expected to rise with higher ambient temperatures.

Final words and conclusion about Silverstone ET750-HG

Silverstone has gone for an internal design as good as the CWT GPS to offer the essential font, for users who do not need frills, but prefer a font that does its job at a lower price. So outside, the source is simple, but it does have a fairly comfortable and versatile semi-modular cabling system that most users will appreciate.

Inside the fountain, the use of a fairly modern internal platform with DC-DC and LLC technologies is remarkable. At the same time, the protection system is decent enough for most users, including overheat protection.

However, the choice of capacitors is much better, since excellent solid capacitors are mixed with medium level electrolytic (CapXon) and low level electrolytic (Jun Fu, ChengX). We believe that this has motivated the use of a somewhat aggressive fan profile from low loads, since these components must be kept under low load to favor their durability. This, added to the fact of using a fan with low cost bearings, makes this source audible from low loads.

We are facing a low cost source that is safe and adequate for operation without disappointing anyone, to value for those who really need 750W, but its current price seems quite high, since its cost is between 100 and 110 euros, in direct competition with other less basic models. Normally, we should find it around 90 euros, and we believe that it should go down so that the small internal cuts that have been made are justified.

Let us summarize the main advantages and disadvantages of this Silverstone ET750-HG:

ADVANTAGE	DISADVANTAGES
- MODERN AND ADVANCED INTERNAL DESIGN AS THE BASE	- SOME DOUBLE QUALITY CAPACITORS
- SEMI-MODULAR FLAT WIRING, WITH GOOD NUMBER OF CONNECTORS	- LOW COST FAN AND SOME AUDIBLE AT REST
- VERY HIGH EFFICIENCY	- HIGH PRICE AT THE TIME OF WRITING THE REVIEW
- PROPER PROTECTIONS AND SAFETY, INCLUDING THE ESSENTIAL
