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 connecting the green cable (PS-ON) to several black cables (COM/GRD).
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?
I want to power it without connecting it to the motherboard.
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.
