Thanks for the pin outs. This PS has the v1.0 20 connector plug. I found that out last night.
A little more research and I found a tutorial on this from Murray State IT department. In that document they short out the green PS_ON# to COM through a 10 Ohm, 10Watt wire wrapped resistor. This provides the load needed to initiate the PS start. PWR_OK is not used. The resister is pretty big so I wire tied it to the inside of the case where it is in the airstream of the fan. I did not use the +3.3VDC or the -12VDC, half of the COM, and about half of the +5VDC lines, so I chopped them short and insulated them to prevent a short, then stuffed them out of the way.
A SPST toggle switch was wired up then I put some binding posts on the top of the case, soldered the COM, +12VDC, and +5VDC connections to the binding posts.
viola! A power supply capable of max 5.5A at +12VDC and 66W, and 14A at +5VDC for 66W.
The only thing weird about this is I bought an illuminated switch. With the green PS_ON# wire connected to the positive side of the switch and a COM line connected to the negative side of the switch, it works just fine. If I then add a +12VDC to the accessory side to illuminate the switch, it does that, but then shuts down the power supply. Does anyone know why this would happen?
At any rate, this took just about 2 hours to put together after I got the parts from RadioShack. This is great for those small electrical projects where I need 5 or 12 volts DC and a cell phone wall wart won't cut it! Like building a pulse width modulator for an electric kettle.
