    Hey All -

    I'm getting set to do another ATX bench power supply project. I'm set except that there is an unknown wire. It is blue with a yellow stripe (or yellow with a blue stripe?) and I can't find any internet references to its purpose/voltage. It's a Seasonic SS-350 BS.

    I don't have my volt meter handy at the moment (I'm at work) and was hoping that the AAC gurus would have some clue as to this mystery.

    Thanks,

    Ray

    Where does it come from or go to at present, presumably not connected the to the 24pin conn?
    It wouldn't be green and yellow maybe, if so a ground wire?
    Max.

    It runs to the 4-pin (square, 2X2) Molex connector, presumably to the processor. After some further digging, it seems that some ATX units have a yellow wire with a black stripe that runs from a separate 12V rail. I'm assuming that's what this is. I'll double check with the VM when I get some free time. Thanks for the help.
