    dc-dc psu w/o the computer

    Hey guys,

    i need a power supply that will supply +12, -12, and +5v. my question is... if i get an atx psu, how do i have it turn on if it's not connected to a mobo? yeah..it's a noobish question, and i did search but i either came back with no results or 1000 results. nothing really answered my question though.

    any help would be greately appreciated.

    there is a wire that you short to ground, I dont remember the color of it off hand, but it is easy to find (I want to say its usually green, but I cant remember)

    Also you can get DC-DC PSU's that work as AT power supplys. I have a dual PSU setup, ds-atx running in atx mode with the computer and a opus 120 running in AT mode (configurable with a jumper) for all of my usb, screen, night vision camera and other devices.
