    I just want to see if my PSU is working. I just ordered a Corsair RM 650. I plugged in some fans, because I'm not ready to plug in anything else yet, but nothing came on. Is there something I'm not aware of, like it needs a little more of a load for it to work, or did I possibly get a bum unit. It was refurbished. Are there a few tricks I can use to tell if it's working. I've seen a paperclip method, but all the cords are black. Anyone have any suggestions?

    Thank you.

    Probably need to have the main connector plugged in before anything starts. Thats why you always have to jump a couple pins in it to get it to turn on.

    You typically need a 'power good' signal to 'turn it on'. Usually you can bridge the green 'power good' to one of the black ground wires and it will start providing power.

    You could probably pull up the ATX spec and count pins:
