well your going to want at least 550 watts. however dont overlook the amps on the 12v rail like a lot of people do. the 9800 requires 450watts and 24amps. the psu i recommend above will handle that rig no problem and its not too costly.

A 650W should be good providing you do not overclock.

Just found out the card needs 24A at 12V. and the supply only gives like 16A at 12V so i think it wont be sufficient ,will it?¿
cheers
