Im about to upgrade my computer from some crappy mobo with 256mb PC133 ram to an epox 8rda+ w/2 256mb PC2700 sticks. My question is, do i need to upgrade my 300 Watt PSU to handle this or would my current one be enough? The rest of my computer consists of 2 CD drives, 2 HDs, Radeon 9000, and an athlon 1800.
