Unfortunately you're going to want to up it a pinch, within the realm of reliable brands. 2x 7950 cards are gonna draw about 700 watts in total with the rest of your system and require four 6-pin PCIe connectors.

Try this, great value

A quality 750W supply should be sufficient, and without breaking your bank. However it's never a bad idea to go 100-200 watts in overhead either.
