enough to SLI GTX 480s

Calculators are so inaccurate.

You have 2 guys in this thread saying you'll be fine.

Being its a 850w PSU means its probably good for upto at least 875 to 900w

Yah, only because it's a Corsair AX series though. That is not a general rule. I'm also saying it's okay, just right on the edge and into the inefficient part of the power curve. If you are folding or crunching BOINC/SETI etc it would be running hot constantly.

I have been thinking about it. I have had cp-850 and before that tx 750 by corsair, and this has been the best psu by far i have ever owned. It's so quiet, I mean the fan doesn't even run only if I run folding@home. I just dont want to take a risk. I would also not feel comfortable running it to the max or close to it. I think perhaps I would just sell the 480 and get 2 460's or 2 470's as they are pretty damn cheap now!

Thank you so very much. The psu estimator says I can tho lol

Honestly I wouldn't worry about it... invest in a power meter if you are concerned, they are only about $25. @ Canadian Tire. Using a Corsair HX 850 psu I ran an I7 970 @ 4.2 as well as 3 overclocked GTX 260's in one of my folding rigs for around 6 months 24/7 with narry a hiccup... Power draw using a meter was only around 650-700 watts IIRC. A highly overclocked 2600K system probably only draws around 200-250 watts minus video card (s) and I doubt 2 GTX 480's would draw more than 450 watt under load... Even if you are pushing 700 watts at full load I'm sure the Corsair can handle it... Unless you game 24/7 or plan on folding 24/7 long term I think you'll be fine.
