EVGA offers one of the most complete lines of PC power supplies on the market today and they are continually striving to improve their product offerings. The new Supernova G3 Series power supplies are based on EVGA’s popular G2 series but now come in a smaller chassis measuring only 150mm (5.9”) deep. The G3 Series also uses a 130mm cooling fan with a hydraulic dynamic bearing for quiet operation and EVGA claims the new G3 units offer even better performance than the G2 models. The Supernova G3 Series is now available in five different models ranging from 550W up to 1000W. We will be taking a detailed look at the Supernova 850W G3 power supply in this review.

Who cares about the 850W? The 1000W version has been reviewed more than 2 months ago by jonnyguru

PCPER always showing us the latest and greatest! Where is the "I sold my soul to nvidia or EVGA to get a free trip to Vegas" sticker on this "article"?

Who cares about 1000W? No relevant combination of modern hardware requires even remotely that much power - an OC'd 6950X with Titan X Pascals in SLI might edge over 700W under power virus loads, but nowhere near 1000. And under normal gaming loads power draw would be far less.

Now stop being an a**. This is a well written and researched, thorough review. And of course JonnyGuru gets an early sample - OklahomaWolf is pretty much regarded as the bee's knees in PSU testing. He probably gets more or less what he wants*. Publishing a high quality review now that units are actually available seems like a good idea to me.

*at least as much as any HW reviewer does.

What? this was such a well-written review. No disrespect to JohnnyGuru, but doesn't even take noise measurements, which are arguably one of the more important things to take into account when purchasing a consumer power supply...

Does this site ever stop hocking keyboards and powersupplies?

Positive review of a good product != hocking.

Quality PSUs don't get the attention they deserve/should have. The importance of including a good PSU in your PC build is something that needs to be communicated more, not less, and reviews like this are a part of that. Of course, there's also the tendency for makers of low-cost crap products to not send them out for review, which unfortunately few publications have the funds to do anything about themselves.

Last 2 EVGA power supplies I tried in the past few months were both DOA. Have gone back to Corsair.

Hocking: to spit up phlegm. To pawn. etc.

Hawking: to sell aggressively; to hunt with bird of prey. Also Stephen Hawking.

The ripple / noise is excellent. I haven't had an EVGA PS fail yet, might be lucky.

This is a good, in depth review. You, Anonymous, are clearly just a flinger of shit, a fool, trying to rise to the level of a troll. Doubt you even read the article.

PCPer, sorry about the shit flinging monkey there. Good article.
