    M2-ATX and 4-Pin mainboard power

    I want to use a Abit NFS mainboard for my car PC, but it needs a 4 pin power plug in conjunction with the 20 Pin power plug...
    Is it possible to splice the 4 Pin in off the 20 Pin? Adapter?

    What kind of 4-pin? If you look at the M2-ATX there is a 4-pin P4 style power connector in addition to the 20-pin.

    Okay, just to clarify...
    1 X 20 pin
    1 X 4 pin
    1 X HDD molex
    1 X Floppy Molex

    Do you have a link to the MB spec? Still need to know what type of 4-pin...

    I've heard of some people doing this and having it work.
    I wouldn't recommend it, however. There are PSUs that provide the 4-pin 12v connection such as the M2ATX, DSATX and the newer Opus units.

    It's the 4-pin square 12v aux power connector, I'm certain. My Shuttle mobo uses it.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Well I did the same thing with my MB that has the 12V P4 connector using an M2-ATX. You need to short pins 13 and 14 on the 20 pin connector to get the PSU to switch on, in addition to providing the 12V over P4 connector.

    So you don't need to splice if you have the M2 already but I believe there are more ideal solutions out there.

    EDIT: Nevermind that. You have the 20 pin ATX on your MB also...

    I'm looking to use the M2...so it DOES have the 4 pin square MB plug?
