500w power supply if its the 500B  B2 BQ W1 N1 are not ok. version is fine for 9020 3670 etc and a 75W card. [URL] [URL]     Power supplies have more than 1 rail and more than a single spec of Watts. You CANNOT USE max power on all rails at the same time. Which is why the combined power is very specific for 3.3v/5v rails. Dell W299G/J556T  875w unit has 225W on those rails and 32 amps for 5v and 30 amps for 3.3v some other vendors have 90 to 130W max  combined for 3.3v/5v even for their 1000W units which is why there are problems. Dell has 150W combined for 3.3v/5v on their 305W power supply. [IMAGE]power 305w [IMAGE]note amps and watts on ALL Rails
