What PSU needed for 670 sli?

[cHk4]

I've ordered https://www.overclockers.co.uk/showproduct.php?prodid=CA-011-XF but talking to someone I know he doesn't think it's going to be enough to run 2x EVGA GeForce GTX 670 Superclock w/Backplate 4096MB and an overclocked 3930K.

Do I need to quickly chance my PSU I've ordered before dispatch or is this fine and he is chatting rubbish?

that's more than enough. anything above 800w should run sli fine (as long as its a good quality psu)

That will be more than enough to run 2 gtx 670

Even a 750W is more than enough for an overclocked system running two cards in SLI. When you take a reading from the wall you'd be surprised at the numbers being drawn.

even a good 650w would easily be enough

Do you really need 1000w? I'd change that to a cheaper psu if its not too late.
