Default Re: How big of PSU will I need?

I believe that motherboard draws power for the CPU from the +5V rail.

The Radeon 9700 also draws substantial power from the +5V rail.

I'd suggest getting a supply that provides at least 200 Watts for the combined 3.3/5V rails alone. (And, because newer motherboards draw CPU power from the +12V rail, if you want the supply to have any long term usefulness, it should have a substantial rating for the +12V rail as well.)
