    M2-ATX not working

    Hi, I had finally got all my parts a couple weeks ago and hooked everything up. The only problem now is my PSU (M2-ATX) is not working at all. I am using a Via Sp-13000 board. When I hook up power (I have tried both in my truck and on an external 12V power supply (rated for 400 watts) nothing turns on. I have checked the fuse and its fine. When I test the outputs of the atx 20 pin connector I get the following the results on the multimeter:

    Pin 2 - 5.54 Votls
    Pin 14 - 5.52 Volts

    Everything else registers 0 Volts.

    unfortuntatly I bought this PSU 6 months ago (ebay - short-circuit) so I doubt there is a possiblity of a return/replacement.

    Any idea's or am I SOL?

    Thanks

    Put a jumper across the PS_ON# to a COM and it will activate the power supply. Then you should be able to test all the outputs.

    Also, be sure you have the power, remote, and gnd connected to the power supply. All three connections are necessary.

    Thanks, that worked great. All voltages when jumpered are fine. But now I don't know why its not turning on. I have the on switch connected to the right jumpers on the motherboard, but still nothing. Any more suggestions?

    Make sure you have the jumpers on the M2Atx setup correctly the section below the PIC micro.

    when you say remote, you mean the ignition wire, right? for signal?

    You need both Ign tied to a switched 12V source and the remote on header next to the ATX header picture about its the 2 pin header in the middle this is cabled to the two pins on your mother board system header that should say PWR_SW or PWR_BUT, or something to the effect of power on and when you have the ignition signal high (12V) then the M2 will attempt to power on your motherboard like a button press on a desktop.

    Yes, Ignition. I forgot that there was a remote out on the power supply... Don't use that as an imput.

    I believe it is to trigger the another device, like an amp.

    I use my remote to power the amp and the fan I glued on top of the M2-ATX
