The EVGA Supernova 850W G3 power supply is rated for a combined, continuous output power of up to 850 watts at 50°C operating temperature. The PSU incorporates a single +12V rail that can deliver up to 70.8A (849.6W) on the +12V output.  The PSU includes universal AC line input (automatically adjusts the AC line voltage) and active PFC, which makes the unit more environmentally friendly to the local power grid.

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.

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.
