I'd like to keep this under $60 shipped if possible, but I can go higher if its needed, the lower the better tho.
This PSU claims +3.3v @ 28A / +5v @ 35A / +12v @ 17A
The +3.3 and +5v rails share 220w, the 12v has 204w.

I'd prefer something that can hold up the +12 a bit better, this system has 3 hard drives, 2 cdroms, CPU is an Athlon XP @ 2.4 GHz & 1.8v, FX5900 ultra (leadtek, 450/900 MHz). The new PSU does not have to be able to handle a more recent video card or more drives, it won't be included in my next upgrade.
I prefer Newegg, but as long as a place has a good reseller rating I'm not too picky.
