No, with a quality PSU like a Corsair TX650 he will be MORE than fine

I have a 750W for x2 HD6970's and I never seen it above 400W-420W

That's why I said their was room for upgrading. It won't kill you or your wallet to upgrade to a higher wattage PSU if you are thinking about buying a new one anyway. Especially a high quality 700W should last your more than a couple years under high load. Just sayin'. Depends on how long he's had his current one too.

True, a good PSU like an XFX 750w Black Edition or a Corsair HX750 would give him future proof in case he grabs a pair of high-end GPU's.

Sounds like 2x 5870s 2GB in cfx. If they are nearly touching in the first two 16x slots in my mobo they sound like a hovercraft. Only way to keep them down in temp tho .

+1 a quality 650w is fine. But if you want to see some really high wattage loads, run furmark and prime95 at the same time. I saw ~550 with my sig rig Witch is pushing the bounds of a 650 watt. You have to remember the 650watt is the total wattage, including the 5v and 3.3v rails. However, a majority of that 550watts I was using was off of the 12v rail
