You'll want something around 550w. If you pay your own power bill you might want to check out a platinum level power supply like my sig says, they save you a large amount of money and pay themselves back within 3-4 years if you run your computer at least half the day.
A good quality 500 watt power supply with about 40 amps on the +12 volt rail(s) and two 6-pin PCI-e video card power cables is more than sufficient for your system.
I maintain a list of recommended power supplies. The recommendations are based on web sites that have the proper equipment and people to conduct rigorous testing and in-depth analysis of components. Here is the link:
