How to test a PSU if all I have is a mobo?

post #1 of 11
Thread Starter 
I got a CP-850 from another user ahead of time, thinking I would use it in a P183 case. Well now that I'm going with a different case, I need to sell the PSU.

At the moment I only have mobo & ram (in sig), so I simply plugged the main connector into the mobo and turned it on. The green light lit up on the mobo, but the fan never spinned. Is this normal since there's no real power draw? I will do another test once my CPU & GPU arrives, but until then, what's the way to test if a PSU is in working order?

You dont even need a motherboard.

Just use a paperclip, And on the 24 pin connect the green wire to any black white

Now when you turn the PSU on it will start up.

Definatly, Its the same as pressing the power button on your PC,
If you google

' Jump start PSU '
you will get many videos etc of people doing it.

Just make sure you only connect the green too the black, Nothing else

Thanks! That was easy... the fan turned on when I did the paper clip test.

Just to avoid any confusion I think you meant to type 'wire' instead of 'white'.

Connect green to black.

Get a paperclip
Bend it into a U shape.
Put one end into the GREEN pin
The other end to the BLACK pin
The PSU should turn on.

Only use pin GREEN and BLACK. Nothing else, or bad things will happen.

Just curious, what would happen if green was connected to non-black?

Was going to say the same thing. Can't remember if there is a white wire on a PSU or not, but dont connect the green wire to anything else other than black! (ground)
