those cards consume over 200 watts each, you will need at least 500 watts power supply to run them

Don't listen to him any good quality power supply with 350-400W will be enough to run card like this.

Anything with 400W from tier 3 or better will be enought for your system.

350w? that is pushing it, the graphics card alone needs 250w, add CPU, RAM, hard drive and DVD burner and you got yourself a system that will need more than 400w to run smoothly, you could run it with 400w power supply but your system wont last  very long, power supply is probably the only part you should not cheap out on when it comes to PC.
