    Need 20 pin plus 4 pin PSU

    My mobo requires a 20 pin molex connector and a 4 pin 12V molex connector. I was looking at getting the 120W Opus PSU but I can't tell if it comes with the additional 4 pin connector or not. Pictures look like yes, manual looks like no. Is it possible to build one if it doesn't? I have the connectors and pins at work.

    I was also wondering what gauge wire I should send to the PSU. I know this question has been asked a million times but I just want to make sure. The FAQ says I could get away with 14 guage, is this true? I have max 10' to go and this is my system:

    POWER CONSUMPTION
    ITEM.............................................. ......AMPS (A).......VOLTS (V)............POWER (W)
    AMD Athlon 64 1640 2.7GHz............................................ ..................................45
    Sirius SC-C1 with Mitch's adapter....................1.00.................12 ........................12
    BU-353 GPS Receiver....................................0.5... ................5.........................2.5
    Rocketfish Bluetooth USB Receiver..................0.5....................5 ........................2.5
    Lilliput 889GL-80NP/C/T................................................. .................................<9
    Panasonic Slimline DVD player............................................ ..............................5
    HDD............................................... .................................................. ...........10

    TOTAL............................................. .................................................. .........86

    I would say the Opus 120 with 12 AWG wire at least, probably 10, is you can. Which 4-pin molex do you need? The one for the processor or the 24-pin ATX connector?

    This 4-pin plug(for the processor):


    Or this one (24 pin ATX)?:
    I have bad luck with vehicles...

    You can build or purchase a cable that taps a HDD power connector to supply the additional 12v to the 4-pin plug.

    I recommend 12awg at a bare minimum, even for a lower-power system such as yours.
    Don't forget the fuse!
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    Looks like the first one.

    Thanks to both for the guage recommendation too.

    The Opus 120 comes with that plug(or, at least, mine did... )
    Worst case senario, you have to buy a $5 Molex to 4-pin P4 connector

    Thanks, that's all I wanted to know. Their manual is deceiving since the 360W one says it has it clear as day.

    I can build my own from parts from work for $0. I just wanted to make sure if I spliced it in somewhere it wouldn't cause problems with something else.
