EVGA SuperNOVA 850 GS Power Supply

EVGA’s been sending me a lot of stuff lately, and it’s all been pretty awesome. Today, I’m looking at their new Silent Series and starting things off with the 850 watt model. This unit is 80 Plus Gold, with a single 70A 12V rail. Why this unit and not their Supernova G2 model? Come on in, and we’ll try to answer that question.

Good day, folks. We’re exploring the lands of EVGA once more today, as we take a look at yet another new line of units from them, the Gold Silent series. You might be wondering what makes this unit any different from the G2 850 watt unit I reviewed a while back. I’m wondering that same thing myself, so it’s a good thing we’re all here today.

On the surface, it doesn’t look like there’s much about this unit that sets it apart from the G2 unit. It’s fully modular, just like the G2. It does the whole single 12V thing, too, and is also rated to fifty degrees.

But there is one major difference… this one didn’t come from the Super Flower factory. No, this one came from Seasonic.

And there are many possible reasons for EVGA moving to Seasonic on this line of units. Maybe Seasonic offered a better deal. Maybe the Super Flower deal is near end of life. Maybe these are quieter than the Super Flower models and more deserving of being called a silent series of units. But I suspect the truth is that EVGA is now selling so many units that Super Flower can’t keep up with the demand, and EVGA needs something just as good to fill the gap. And really… Seasonic is the natural choice, there.

Even so, there is a difference in the warranty length between this series and the G2 series. EVGA does ten years for the latter, and seven years for these (they’ve just increased the warranty length of these, in fact). So, the implication is that these units are taking the second banana position over at EVGA with the Super Flower originated units sitting on top.

Let’s do some unpacking, now.

Inside the box, I found a power supply in a bag, some modular cables, a power cord, a user guide, some screws, a self-test adapter, some velcro cable ties, and a modular cable bag.

The manual is more than an adequate effort that gives us just about everything we want to know about the unit, including specifications.

The self-test adapter is pretty much the same thing we’ve seen with all recent EVGA units. You plug it into the end of the ATX cable, and it forces the power supply to turn on by pulling the PS_ON wire to ground.
