Athlons take a lot of amps from certain supply rails. Depends on the 
motherboard CPU supplies as to how the PSU gets hammered. The overall
wattage usually isn't an issue. The peak amps on each supply rail can be
a problem...

Also, take care with the connectors. Only a very small resistance can
cause significant voltage drop and heating.

Good luck,
