Motherboard pin connection

  1. Jan 12, 2013 #1
    I am connecting my towers power wires to the motherboard.

    The motherboard tells me how to connect the. Hdd led cable. And were the pluss and minus wires go.

    But the. Hdd led cable is mad of a. Blue and white wire.

    Witch one is the pluss. And. Negitive?

    Re: motherboaer pin connection

    The white wire is customarily the ground wire [negative]. If you look closely at the connector, it is likely marked showing the polarity. It is unlikely you will fry anything if you have it reversed. If the led light doesnt work, reverse the connector and try again.
