750 is enough for prety much any 2 card system, gtx 480 needs 850w, but gtx 580 only requires 750w, and your 2x 6950 setup is not going to be close to sli 580s, you will be fine,

we NEED a sticky for this!!!!!!!!!!!! not just in the power supply forum, in nvidia and ati forums as well, have a separate thread for nvidia and ati, and sticky them!!!!!!!!!!!!!

edit: you also need a quality power supply, i don't know if that psu is quality, but it IS seasonic so chances are high

SS-750AT is what is used in the Corsair TX750 V2 and XFX Core 750W. It's not amazing top-tier quality, but it's very good, particularly in +12V output ripple and voltage regulation, which is the most important (for overclocking and in general). And that's plenty of power for that system, with lots of room for overclocking, particularly since we're talking about a i5-2500k. An i5-2500k P67 system overclocked to reasonable 24/7 levels should use a decent bit less power than something like a stock i7-950 X58 system anyway.

Yes, 750w is enough.

k, i think ill go on him.
and 1 more question, the asrock board i'am taking, hes go power V8+2 phase, would it change the stability, because the PSU is 12V.
thank you very much.

The 8+2 phase is how many mosfets control the power to your CPU. It is completely different from the PSU. And 8+2 is enough to get a solid 5GHz+ overclock, assuming your chip can do it.

The entire parts list you have picked is a solid choice (assuming the RAM is at least 1600 and you're getting it cheap, and the GPU's aren't XFX).

DDR3-1600 @ 9-9-9-24 isn't anything special. But if the price is right, it's definitely not a bad choice. You won't NOTICE the difference between those and say 6-7-6-18 RAM. But it is always better to have better RAM when you can.

But again, there's nothing WRONG with 9-9-9-24 for 1600. It's just not all that great either. So if the price is right on that kit, then go for it. If you can find another 2x4GB kit of 1600 with tighter timings (and 1.5-1.6v) then get that instead.

EDIT:
For reference, my Ripjaws are 9-9-9-24 at 1600, and they go all the way to 2133 @ 9-11-9-24. So again, there's nothing wrong with it. Was just offering a potential place for a minor upgrade if its possible.
