  • M2-ATX-HV No Power D945GSEJT MB

    I have installed a M2-ATX-HV power supply in my jeep. I am using an Intel D945GSEJT motherboard. I ran a + and - wire from the battery and light tested them and they are working. I ran a wire from the ACC and light tested it and it is working. When I start the car, I get no power from the 4 pin connector. The motherboard only has a 4 pin connector and not the full ATX connection. I connected a 4 pin connector from an ATX power supply and the board showed the green power light on it. With the M2 I get now power light or anything.

    Does anyone know why it isnt giving me power?

    EDIT: Forgot to add, I am running 18 gauge wire from the battery. Is that too small?

    Since Im not connecting the normal ATX connection to the board and its not starting, would I need to plug that connection into the PSU and jump it off like you have to jump a normal ATX power supply to use those rails?

      18awg is probably too small a wire.

      And you're using an ATX power supply with a non-ATX board. You need to "fool" the M2 to think it's on.

      Frankly, I think there are better solutions than a kluge job like this. others have gotten it to work, and you probably can, as well. But you're using a PSU for a job that it is not specifically designed for.
      Have you looked in the FAQ yet?
      How about the Wiki?

          I recommend reading the FAQs, where you can easily determine an appropriate PSU for your setup.

          There's a link in my signature.
