    Post DC Power Supply

    I know this has been discussed before but what do you need to do so the DC powersupply will work ? I am talking about the power good signal some motherboards require. I remember seeing something about it awhile ago. Thanks for the help.

    Cool

    Only some motherboards require power good.

    As far as mimicking the signal, all you need is an RC (resistor capacitor) network to deliver a slightly delayed signal. Any electronics text will have the circuit diagram. The values of components you want to use are a 10K resistor and a 470uF tantalum capacitor.
