I purchased a Fong Kai 603 with an Enhance 250W PSU, which is said to be a pretty good PSU. Anyway, I'm putting a DVD drive, CDRW, one HD, a floppy, and two case fans in the system that will be running off the PSU. The cpu is a Duron 1000. I'm not sure how much juice those Sunon case fans use. Do you think this PSU is sufficient?
