Title: AT Power Supply Questions
Post by: testicle187 on July 19, 2005, 02:55:24 pm

I am in the process of wiring a seperate AT power supply to power the fans on the on rear of my arcade cabinet and am wondering what I need to do to get it where when I flip the power supply Switch to "ON" it starts the fans running.  Is there a set of pins I need to short out?  Or perhaps a walkthrough for hacking an AT power supply on this?  Thanks in advance for the help.

Do you mean AT or ATX?

AT PSUs dont need the pins shorting, ATX do.

The lower part of this thread should help.

Mine is actually AT, but I was wondering how I would go about disabling the Power button that is attached to it.  So that when the switch on the back of the PSU is turned on it powers up.  I know I can leave the front power button clicked in, but was wanting to eliminate some wires if possible.

IIRC,

AT PSU has a toggle switch, meaning it's always ON or always OFF, no momentary business. If that's true you could turn the AT power supply ON and connect it to a "smart strip" that is connected to your cabinet's PC, then it would turn on and off with the PC.

As for "eliminate some wires" - simply cut the wires off that you aren't using. (probably all but 2)

What is the AT PSU being used for?
