How much Power should I have for GTX570 Sli?

[Ridalin]

Like the Title suggests, I'm hoping I can Sli with enough power. I already have 1 GTX570 barely a week old and working fine.

GTX570
PC Power and Cooling Silencer Mk II 750W
And the Mobo, incase that matters... but it is Sli ready.
GIGABYTE GA-Z68X


P.s. What are the advantages working with sli? I do much PS and FW (2000x2000 sized pictures, Hard gaming with Metro and Sc2, and Sims3. As for CPU, I have a i7 2600k.

Thanks in advance!

Yyou miight actually be fine... Thats a quality psu, and a good size.

I THINK YOURE good, as its 550W for 1, add 71 moredat load, give bout 650W total.

THanks, for some reason I thought the 550w requirement added together, for 1100w needed...but I knew that couldn't be right....lol

Thanks, I'll go ahead and get it, and while I'm at it, I'll get 2133 ram with it.

Thanks again, love this community!

Crap I forgot, i was wrong and ment to ffix this... Its actually 140W at load per card. 70W is idle.

550 is the amount for 1 card and all system components. I ran sli 260's on a 700W Silverstone with no issues, which run alittle less per card, but not much at all.
