    On my giga-byte mobo, ga7dxr+, there is a white, 3-pin, connector marked "pwr fan" which looks like a fan connector.
    Can someone tell me what this is and the correct usage for it?
    Been to giga-byte site & looked thru my documentation but have not found explanation.

    Some power supplies have a fan connector that you can connect through the motherboard, allowing you to monitor the PSU fan RPM's. It's basically just another fan port, and you can use it for any fan in your case, it doesn't have to be from the PSU.

    McTimson,

    I thought that was it but, I guess I just look too hard at everything. (or am just ignorant)
    I look at the obvious and I think; does that have sufficient ampacity? Is it analog or digital? Is it for peripheral power or just tach? etc. Is it some proprietary connector for giga-byte use?
    So, thank you for your information.

    Fans typically consume from 2 to 4 watts, and the MB connectors are up to the task of providing that amount of power. :) The benefit of using them is the speed monitoring.

    The connector is an electrical 12v current (red +, black ground) and the yellow one is an analogic speed measurament.
    This kind of connector is standard; if you want a case fan, it will came with this connector, and you'll be able to monitor it's speed in RPM in the bios or using some software as "Motherboard Monitor" (http://mbm.livewiredev.com)
