Old power supply- new pci-e motherboard!

    My brand new SLI motherboard has got a 24 pin power connector, and my power
    supply has a 20 pin power connector and another lead which looks like 4
    power pins (what are they?) Can I use the 20pin cable and put the 4 pin
    cable in the missing holes?

  2. Thats what its made for. Just plug 4 pin connector into "missing holes"
    and it will work just fine.

    Thanks! I'm assuming I have to be careful what holes I put the two
    connectors into?

    Not sure if the additional 4 pin connecter you reference is earmarked for
    another socket. For instance the DFI SLi mb requires 4 power connections to
    the mb for stable SLi mode. A 24 pin main, a 4 pin atx 12 volt, a hdd and
    floppy drive power lead. Four connections total. Your motherboard manual
    should show how to make the proper connections.

  5. There is only one way to put them in. Otherways they wont fit.

    Dan for Christsakes don't do this the seperate 4 pin connector is not
    designed to connect there. The 4 pin has its own header usually close
    to the processor socket. The 24 pin ATX power socket is designed to
    accept either the standard 20 pin plug or the new ATX 2.0 24 pin plug.
    The M/B should come with a blanking plate fitted over the spare 4
    sockets which are left over if you use the 20 pin plug.

    No, but you can get a 20->24 pin adapter (ATX->ATX 2.0). The 4 pin
    connector is an extra +12v connector. Should be a place on the MB to plug
    it in. RTFM.

    Well I don't think it will fit and that's a good thing since it would
    probably blow the MB. That's NOT what it is for. Suggest you check the
    difference between the ATX (20pin) and ATX 2.0 (24pin) specs before you
    spout such trash again. The 4pin (P4) connector is 2 +12v pins and 2
    ground pins. The extra 4 pins of the 24 connector are 1 each, +3.3v, +5v,
    +12v, and Ground IIRC.
