    Default Testing a PSU

    Is there anyway to tell if a PSU is working properly without a motherboard? I just bought an Antec Truepower 430W, but I don't have my motherboard yet. If I plugged it into the wall, will the fans turn on? How do I verify it works?

    Do not attempt to use your power suppy without having it hooked up to something. Can't remember who/where I was told that operating without a load is not a good thing for a PSU but it seems to me that I did trust the source. In addition to the possible risk there is the fact that just because the fans spin up does not really tell you anything about the proformance of the PSU. There are test light units that the main motherboard plug can be attached to to verify that all rails are functioning and I suppose one could find out how well the thing funtions by using a volt meter .... best bet is to leave the thing alone untill you have the system.

    Crude but Effective ... it is a way of life.

    i think that operating without a load was only a problem on the old at power supplys.
    to power it up without a motherboard locate the green wire on the atx plug and then stick a paperclip in it, then put the other end into one of the black wires and the psu should turn on

    it is still prefered to have the PSU plugged into something, even if it's only a fan. To test it you need a decent muti-meter

    You either need a mainboard to test it or ground the Power On wire on the mainboard plug (pin 14 to pin 13).
