SilverStone ET700-MG Power Supply Review

Efficiency

With the Silverstone ET700 being officially specified as having a ‘Gold’ efficiency rating, one of the most critical factors in our testing is checking this to not only see how accurate that description is, but also where the land truly lies in more accurate figures.

Achieving over 90% in all of our tests, this power supply comfortable meets its ‘Gold’ rating and in many respects comes close to Platinum. While it does definitively fall into this category, what we can confirm is that by ‘Gold’ standards, this is on the very high end of the scale.

PFC (Power Factor Correction)

Although starting off a little on the low side, this is neither unusual nor uncommon for the vast majority of power supplies we test. What is important is that as you crank the power output up, that figure should start to increase quite significantly. As you can see below, achieving over 0.95 at 100% is not only what you want to see, it’s actually quite a high score and overall, we find the PFC results very good.

Voltage Regulation

We would concede that the figure provided in our voltage regulation tests give us some of the most ‘mixed-bag’ results we have ever encountered. Across the various power outputs, the figures seemed to show very little consistency and while not concerning, this is certainly unusual and possibly some quirk with the design.

As you might expect, such mildly inconsistent results do provide some unusually high levels of deviancy. Based on the results as a whole, however, we do not find anything overly concerning here.
