Eh, I'd say cuttin' it very close there, especially with your overclocked CPU. Wouldn't run them on anything less than a quality 850w PSU:

You could get away with 750W, but I would agree to swap to a quality 850W if you're able.

I'll be buying my second GTX 580 sometime this month to SLi, too. I bought this AX850 just for that.

Scroll down to see the power consumption graphs.
Idle: 205W
Load Crysis: 620W
Load Furmark: 777W

I can't find the full component list that they were using but I can't image its more powerful that what you already got

I know that quality power supplies can deliver a lot more than what they're labeled. I've read reviews that said my 650W PSU delived up to 780W under load. I'm guessing 750 should be enough then.

I repeat, 850W is plenty for a system with 2x 580s and an OCd chip. Even has some headroom on top of it.
