A 600-650 watt psu 80+ bronze should be a real good match. It should be able to run on 550 watts ok, but you're better off with the higher wattage for extra room. Also look for a psu that has a single rail, they are usually better for crossfire setups.

A quality 500-550W would be plenty unless you're running something like AMD FX-9590 or similar. Those cards are like 100 tdp each.
