How to turn on PSU without motherboard?

How can I turn on an ATX-PIV 400WATT power supply without connecting it to a motherboard? I tried connecting the green cable (PS-ON) to several black cables (COM/GRD).
- This model doesn't have a switch.

If you unplug the PSU, jump the Green connector with any Black pin and plug it in, it should be on. I usually use a paperclip bent in a "U" shape.

No switch, does it have a button? As far as the wire it should be the black one right next to the green

If you jumpered the green to a black and it didn't turn on, that would indicate a defective power supply.

I tried jumpering the green connector with several black connectors with no success. Its works fine when connected to the motherboard. It doesn't have a switch/button.

that only test the power up signal, if it works for the motherboard then exactly what are you trying to do?

Good point, Dude. It works, or at least it powers on with the PC power switch.

To use as power for something other than a computer?

When I was prepping my case for my new rig, I did it to make sure the custom cables were wired correctly and to make sure the fans worked ok. It also made sure the PSU worked.
