power supply question...

**fkdup74** · 01-25-2005, 05:13 PM

anyone know of a way i can get a power supply goin w/o a mobo?
ok, say i want to test a fan....
instead of having to switch my pc on & off, connect & disconnect stuff, etc....
i could just have a PSU plugged in,
and switch it on & off to get power to the fans
or something to that effect...
i just wanna get power from my wall outlett to a 4 pin connector...
w/o having to f00k about inside my case

ahhh, thanks for the extra info VB
guess i kinda figured there could be some risk
but i can use the pin jump for a down & dirty test
then go bug radio shack for a way to replicate the signal later

So there is no way of using 2 PSU and one motherboard?

but you'll need to google it,

you could use a relay to make one PSU turn on if the other is giving power. Seaqrch google for relays and you should figure out what i mean.

to turn on PSUs you short the light green wire to any black\ground wire.
