Here's a rough guide to psu consumption I made from either Andatech or
Tomshardware sites. The -3.3, -5 and -12 don't count for modern ATX boards.
The 5.1 current includes 1.75 current for the P3-933 cpu. Which explained
to me how a 230w rated psu delivering 100w and only 5.5a on the +12v manages
to drive a cpu, mb, floppy, cd, hd and fans.
