How much W does 1024 MB Ram use?

Was looking at ocz 420 w psu, and it has 92 w on the 3.3 line..is that enough to handle my x800 pro and 1024 mb ram?

afaik, every stick of ram pulls about 10W off of the 3.3V line.
Your x800 takes its power mainly from the 12V line.. there shouldn't be problems with this psu. If you're worried about it, you should check the 12V ampere rating, because this is the most used rail (used by cpu,mb,gfx,fans and drives).

RAM modules use ten watts!?!?! that seems extremely high.
