If you want the power on your computer to come up when you power up your cab, you can attach a 10uf 16v capacitor to the power on pins. Just make sure and meter it first to see which pin is '-' and which is '+'. |

The power-on jumper for ATX motherboards (the current standard, the one with the large 20pin molex) is done by shorting the green wire with ANY ground (black) wire. using a momentary pushbutton switch. All the front panel is is a connection from the green wire to the common ground on the mobo then you connect a switch to those pins on the mobo and you have yourself a power button. This is a trick used to test PSUs or other devices w/o a mobo, just by sticking a paperclip into the socket for the green wire and then into a socket for a black wire and it starts up. Note that the momentary pushbutton is only used when conencting to the proper pin on the mobo. Shorting the wires requires a constant connection (or the use of a relay if you choose). Which I have done in several PC projects of mine. Annnnyways, with that information out of the way, the easiest way to do a button hack is take off the front cover and look at the pwr button, note what color wires it uses and trace it back to the PC. Those are the pins you need. Or simply clip off the pwr button extend each wire to where you want the pwr button to be and re-attach the button and your done. piece of cake. |
