  • How to power up an ATX Power Supply without a PC!

    This is the whole story. A long time ago it was true that to get 12V from an AT PSU you had to have a load on the 5V. This is no longer the case unless the PSU is VERY old. Some PSUs have a power SW on the back, some do not. Again, a long tine ago none of them did because the power sw was hard wired to the front panel. It doesn't work that way any more. The units with a SW on the back just have that as a feature.The unit is powered on with a momentary push button sw on the front panel. This sw goes to a ckt on the MB (powered by the 5V that is on all the time unless you turn the main sw off or pull the plug). That ckt latches the green wire connection to ground - the same as what you do with the short from green to black.

SO--if the PSU does not power on in the unit, it could be an open wire to the front panel push button (most common) or it could be the ckt on the MB. It is easy to get the wires from the push button on the wrong terminals on the MB.

    it looks like grounding that will do the trick. Remember the unit is power up all the time. try not to short out something else, though at 3v i probably won't hurt a lot.good luck
