Title: PC Power supply Hacking
Post by: sealslayer on September 17, 2006, 08:27:26 am
I need to run some cold cathode tubes and fans for my cab but I want to use a separate power supply from my PC to keep potential problems to a minimum.
I've been googling and found you can short pins 14 and 15 but it also says you need to have a MOBO attached as the PSU is waiting for a return current to it.
Is there another way of doing this? I would like the PSU to have a switch in the cab so I can turn it on and off manually.
Cheers  ;D

No, that should work just fine without the mobo.

Agreed.  The short works just fine for me.

Damn, I've tried this now on two power supplys and nothing happens, I hope I'm shorting the correct two, theres a clip that fits into the mobo between 15 and 16 is this correct?

Usually it's a green wire.  Short that to any ground.  Ground will almost always be black.

If it's not working, I don't think you're shorting the correct two

Is this info in the wiki?   Seems like it should be since it's a pretty common thing to do.

There's definitely an image out there that makes it unclear if you're looking AT then end of the plug or looking at it from the WIRE side of things.

When I did this (multiple times) I ended up Googling around for a good pic so I could be sure I didn't screw anything up, which is how I found that particular photo.

Good luck
