Worst case stress test should be around or just a little over 600W for both cards combined, considering the slight GPU overclock. An i7-2600k at 4.4 GHz doesn't need too much power, so worst case full power draw for the whole system should be around 760W. Certainly the X760 can do a little above 760W if required, and it's not like you'll get anywhere near these numbers in normal usage. Under realistic gaming loads, you have no need to worry even if you overclock the GTX 580s.
