AT PSU Power_Good / Pinout

I am trying to "Rig" up an old At Power supply for some 12V duty. I can't find a pinout diagram for it. It is the "newer" style AT with the switch attached to the cord that goes to the case front.

Can I Jump the power good wire to get it run ? If so which wires ?

Thanks

Scott

    Flip the switch that goes to the front of the case.

    On an ATX PSU you jump the green Power_Good wire to a nearby ground and it will run on the bench. This is what I am trying to do.

    I need to Know which is the Power_Good pin and what to jump it to. Gnd. ? voltage ? etc.

    It does not run if you just push the button.

    You may just need to put a load on it. Check out the last paragraph at this page.

    A link from that page leads to a circuit diagram which may be useful.

    I'd try hooking a couple HD's and maybe a few case fans to the PSU, then check each lead with a VOM.

    Wow. I do the green wire to ground and have never had one not turn on for a standard atx psu.

    Weird.

    I had several of these on the shelf. I got another one and it worked by just pushing the button. Cool

    So I tried Profs suggestion and hung a huge 120 x 38 sunon fan on the one that would not run and VIOLA she runs. So Prof gets the prize ! ( To be determined at a later date ) ( No not "That" kind of date )
    Thanks Prof !! :thumbsup:
