750w, sli 580?

[StonedPenguin]

Will a TX750w be enough for 2 580's and a clocked 2500k?

I was going to go with 670 sli but with the stuttering problems and taking the pricing into account, A 2nd 580 for £200 is appealing compared to £650 on 670's.
I could sell my tx750 and buy something closer to the 1kw mark but would rather not if I dont have too.

cheers

I do believe that is going to be a no, you can get away with a 850w psu but not a 750w.

Should be okay but 850 would be better. My 570 sli system never used more than 550w from wall which in reality is around 450w used by components

I'd get the 580 first + a cheap plug in power monitor. If it reads more than 700w from wall stress testing gpu's + cpu at same time then I'd change the psu.

Thanks for the info fellas, I just feel about selling my current PSU just for something 100w more, If I buy the 2nd GPU what sort of thing should I be looking out for as indications to there not being enough power?

I've not used a power meter before so wouldnt know where to start with 1 of those.
