    Homemade P4 to P4?

    I don't have the funds for a new one right now, so I wired this up for an m2-atx

    Anything I should be worried about before plugging it in? I used 22-18 Butt Connectors with parallel polarity.

    Should be fine, I've done these as well. Only issue I ever ran into was instability when I used too long of wire.

    If you have the parts, its always cool to make it yourself. My OPUS 320 had that cable, but the MoBo didnt need it so I cut mine off. Well now I have replaced my MoBo and need that plug again, so I simply attached it to the 12V rail.

    Thanks for the tips guys!

    From what I've read, yellow is 12v and black is ground as long as the colours aren't opposed it should be fine. Testing this weekend!

    Couple months old but didn't want to start a new thread for a similar topic.

    I'm thinking about finishing my pc for my truck and my motherboard has the P4 connection. I was going to make my own but cant seem to find the M2-ATX pinout for that connection.

    The above picture looks like it is pin 1-1, 2-2, 3-3 and 4 to 4? I dont want to hook up 12V backwards if the M2-ATX is wired strange. I'm going to build it now. I'll check later to see if i get a repsonse before i plug it in

    okay well that sucked!
    I Had a couple amp 16VDC supply so i thought. M2-ATX wide range input. Should be okay with 16VDC. I turn it on and POP!! wtf! disconect power. Check everything. Damn stabalizing cap blew on the M2-ATX! It's been sitting for months but still.

    Grabbed a PC power supply and gave it 12VDC and everything works. But i have a blown cap on my M2ATX that is not good!

    All that said. The 1 to 1 pinout is good on the P4 connector

    Just have to pull out my PS and replace a couple caps i think now. ;(
