I have an LiteOn OEM PSU that was installed in my Old emachine I wanted to remove it and repurpose it but it seems i cannot power it on when connecting the green wire to ground but it works when it is plugged into the computers Mother board. Im just wondering if there is any way i can get it to power on without my computer.

PSU might require Power_good signal also (+5V on grey wire). Should not require but OEM parts may sometimes be very interesting.

Connecting +5v cable to grey wire then green wire to ground yields no reaction. No voltages on any cable except purple.
I'm thinking it needs a load to turn on? Cause it powers up when connected to the Mobo. How would i simulate a load.

Connecting the green to ground does nothing unless under load.

I don't think the ground wire matters since all the black grounds are connected together

Can you try a ground wire next to the green wire? I know that works.

Try plugging a fan or something in to a Molex first. Might need load to start.

Green has been attached to ground doesn't do anything fans don't even flinch.
I have had fans plugged into the molex and they don't spins and the psu just sits there almost no reaction cooling fan flinched bun no full rotation. I have cut the wires so it's no longer possible to connect to a pc since I planned on using at a power supply for somethings else. I guess I'll have to wait till I get some 10 watt resistors to act as a load.

I have a bench ATX Power Supply that I use for various tests as well as running a spare internal DVD Burner/player.

 

If I connect only a single SATA HDD to the P.S . that provides enough load current to power up and keep the P.S. running.

 

It stays on with a 2.5 or a 3.5 HDD (spinner drives, not SSD's).

I tried but I get not power on any of the rails. I think it's just not working since now the fan doesn't flinch inonlyngetnvoltage on the purple wire. I think I shorted on of the large caps when I picked it up and got shocked (it was unplugged) I guess the caps didn't discharge. Lol. I think I'll buy something else and go from there.
