Would my XFX XXX 650W PSU be sufficient to run two 7950's? The rest of my system is in my sig. Thanks

Does it come with 4 PCIE connectors or are you planning to use molex-PCIE cables for the second card?
It will be close.
3770K @ 4.7 (1.35V) = 220w
7950 Direct CUII @ 900 = 156w (strenuous gaming)
HDD 10w
Case fans 2w each
As you can see you should be fine (your PSU has a good rating) but any more volts are going to push it further.
Close call depending on how far you oc them.
Good psu though (Seasonic?)
Very fine imo. My 7970 is pushing the limit on my 600w really. I would get an 850W if I was going for xfire just to be safe. 220w for a 3570K, really? How is that possible?
A 3770k at 4.7/1.35v uses 220W? That's a big increase from the stock 77W TDP. Mine is a 3570k at 4.2 of course (1.16v load) so it shouldn't use too much more than the stock TDP (I think 1.16v is around stock voltage for a 3570k)
