7970 cf

So I'm here on the forum asking if you guys think that my Corsair 760W Platinum psu would be able to handle two 7970s or a 7970 and a 280x CF? ( Not the that card I currently have is a sapphire trixx ghz 7970) Now I've read on a psu requirement site that it is advised that I have about 800W, but is that really needed if my psu is highly rated among the other things inside my system (OC'd 3570k to 4.5ghz and about three different hdds and a single ssd)

Thanks a bunch!

I think it would be fine. I run one 7970 600 watts. The max tdp is 250 watts for each card.
