    I have a connector on a DFI-brand, Model NB70-SC, Pentium 4 board marked Auxiliary Power, ATXP3.
    • What is it for?
    • Is it necessary?
    • If so, when and under what conditions?

    the Auxiliary connector just provides additional current for the motherboards +3.3VDC and +5VDC.

    Even though it's an Auxiliary, you should probally leave it alone.

    I have built at least a dozen systems in the last year with this board. This is the first time I have bought a case that does not have the ATXP3 connector from the powerv supply. Although the book says it will run okay without the ATXP3 connected as long as the ATX 20-pin and the ATXP2 are connected, I have misgivings about it.

    You see, this NB70-SC board (out of production but still available) is the most stable board I've ever used. I don't want to do anything to jeopardize the stability--especially since this one is going to my attorney.

    As far as leaving it alone goes, that's the problem. This case doesn't have anything to connect to it at all.

    I'll certainly be more careful about the cases I buy in the future.
