    Unhappy

    One of my computers died; so, I bought a ASUS M3A76-CM motherboard and a Elite 310 case with a Thermal Master TM-420-PMSR 420 W power supply installed.

    There is a system panel connector on the motherboard that supports the
    following chassis mounted functions:

    1.System power LED (2 pin PLED)
    2.Hard disk drive activity LED (2 pin IDE LED)
    3.Power (2 pin PWRSW)
    4.Reset button (2 pin RESET)
    5.System warning speaker (4 pin SPEAKER)

    The motherboard shows the PLED and IDE LED to be 1 positive and 1 negative
    pin. What color wires do you think the positive wire would be
    coming from the front of the case?

    The motherboard shows the PWRSW and RESET connectors have a PWR and Ground
    wires. What color wires do you think would be the ground wires?

    The motherboard shows the speaker to be a 4 pin connector with a 5+V wire
    being one of them. What color wire do you think this wire would be?

    Is it common for the EATXPWR wires to be a plug of 20 wires and another plug
    of 4 wires all to be plugged into the 24 pin connector on the motherboard?

    Thanks for the help.

    Were there no instructions\diagrams given with the case? Or motherboard?

    The actual color codes of the wires to the external LEDs can be of many combinations. USUALLY the positive lead is RED but not always. You can do this on a trial and error basis with LEDs. Try one way, if no go, reverse the leads. A "back biased" LED will just not light if the power is reversed.

    The power switch and reset leads can be reversed and work fine, since a switch is a switch. ON-OFF that's it. Single pole-single throw.

    So far as the main power wires ( I think that's what you mean ) a multi-pin connector that is keyed so you can't insert it wrong, is usually the case. The 4 pin connector is usually provided for an Intel P4 CPU board.

    Speaker wires can be reversed without problem. Why are there four wires? Or are only two being used?
    HTH.

    Long ago, there was a time when men cursed and beat on the ground with sticks. It was called witchcraft.
    Today it is called golf!

    Thanks for the help. As you suggested by trial and error, I was able to get the problem solved.

    Thanks again
