For dual 480s, which are extremely power hungry, that PSU is going to be borderline. Minimum recommended is 900W with 67A on the 12V rail - the M2 is rated for 68A. With no overclocking, it'll probably work...for a while anyway. Even with 900W, you're going to have very little, if any, headroom. Actual PSU requirements are always subject to debate since manufacturer recommendations always include a fair amount of safety margin, but I've read quite a few posts from 480 owners that say you really do need a beefy PSU for them. Hope this helps.

thanks for the input-ya I was thinking it would be cutting it kind of close but wanted a second opinion as I'm not super familiar I just know 480s are power hungry, these ones are a 4gb config reference cards-...not sure if the vram makes a difference on power consumption, guess the question is now; New psu, or take that money and put it towards a 970-but I wonder what the performance comparatively would be dual 480's vs 970. Also I don't necessarily plan on oc'ing the 480s-but who knows.

I've never used either card, but just doing a quick scan of the comparative specs I would sell the 480s and get a 970 or a 980. You'll get better performance on current games, with much lower TDP, noise and temps. Just my two cents...
And I thought my 770s were power hungry...

My pleasure. I was just discussing SLI temps in another thread - if you decide to keep them, if nothing else they're marginally cheaper to run than a space heater, lol. I use my 770s to keep my toes warm in my basement office.
