    M2-ATX 4-pin power cable

    I bought the M2-ATX PSU a few months ago and have finally got to the point where i need to install it, BUT somewhere i've lost the 4-pin cpu power cable. I have some old, blown, PSU's that I was able to get the molex connectors from, now I need to solder the 2 connectors together but how do I do that?

    on the 4 pin, there are 2 black and 2 yellow wires, do the 2 yellow need to be switched or not, ya know what i mean?

    in the picture i included, would i solder pin "A1" to pin "B1" and pin "A2" to pin "B2", etc, or would it be something like pin "A1" soldered to pin "B2", pin "A2" soldered to pin "B1", etc?

    If you dont understand me, if someone could upload a picture of the 4pin cable that comes with the M2-ATX I can figure it out from the pic.

    thanks!!

    hmm... after looking at the pictures on the mp3car store it seems that this didnt come with a 4pin power controller. Thats pretty dumb. now how do i connect the wires to make one, cause i'm not spending $10 on a cable!

    there are two black and two yellow. just connect them according to their color. If you just match the number on your drawing, it'll be fine. the yellow provide 12 volts. and the black is just the ground.

    Thanks, I knew the yellow was 12v and black was ground, but i didn't know if for example the grounds were reversed or something. I'll give it a shot and see what happens.
