for load you could use a light bulb 12v or a resistor
accross ground and 5vline 50-100ohm.
and a led on the power good se if it lights.

Can any one tell me how to effect a simple on/off control of a standard
ATX type power supply to use it on bench or for other projects? How
does motherboard control this function?
Thanks
