How to launch the PSU without having it hooked up to a PC?

[Fronic]

I am replacing the fan inside my spare 400 watt psu before swapping it and I'm curios if I could turn on the PSU without having it be connected to a PC?

Short out the green and white wire, on the main connector, with a paper clip and make sure it's plugged into the wall.

It's green and black wire ;)

Actually, I think that there's a few combinations that work. Green and white seems to work on my 20-pin PSU. :shrug:

I just tried the green and black wire trick the other day and it worked great on amy 24 pin PSU. :cool:

Being old fashioned, at least old, I got a PS tester a while back for about $10. Costs a bit more but foes two jobs.

Dont have to worry about the wire falling out while testing.
