remote power switch
I have an old computer without a chassis which I want to do some testing on. The problem is that the ATX power supply I'm using doesn't have an on/off switch so I have no way of turning it on. My question is: Will it help to short the remote power switch connector on the motherboard with a jumper, or is that a bad idea?
ASKER
Yes, that's what I was thinking too. The main point of my question was to hear if it might harm the motherboard if I did it. I don't know much about electronics, so I don't really know what could happen.
I don't think that you will harm the motherboard, but I would check the motherboard manual just in case.
I hope this helps !

The motherboard manual doesn't say anything about that. Guess I'll just have to try.

Well, now I've tried it, and it didn't work. Nothing happened when I plugged in the power cord. Any further help on how to be able to turn on this computer is appreciated. The relevant pin assignments can be seen here: http://www.idi.ntnu.no/~runeberg/pins.jpg
Perhaps it would help to apply a current to pin 18? Any suggestions?

unplug the PS. Look for a green and a black wire in the MB connector and jump them with a wire or paper clip. Plug in the power supply and see if it runs. You have to have it connected to at least one drive.

The screwdriver did the trick. Thanks.
Btw, do you now what kind of voltage goes through the remote power switch? In other words: Can I get electrical shocks from it?

red 2,
You should not get a shock through the screwdriver to motherboard...
you are just shorting a jumper...closing a circuit....I do not know what kind of voltage is passing thru. I just know i have been doing this to test moboards w/out having to plug in all the crap. As well as test power supplies...worked fine for me for years now...

I would test this, since it may only require a momentary contact to turn off the Power supply, and not a jumper.
It is desgined for hooking up a switch I think.
I hope this helps !
