I had a Sparkle 350. I liked it alot, still works. Its running a friends 1.4athlon, six hard drives and two cdroms drives. No problems.
Forton source has some good psu's I believe.
I just bought this one
http://www.directron.com/tt500ss.html I hate the company that sells it. They screwed me once but I buy from them when there is a good deal or they have something someone else doesn't. That PSU is currently running a p4 2.26@2.9 with a ATI 9700, three hard drives and two cdrom drives. My 12v stays at 11.94, which is good because thats what the p4's draw power from.
