    M2-ATX Dead?

    Long time viewer of this website, But i never registered because all my questions were already answer here. Except this one...

    Recently my M2-ATX powersupply started acting weird. When I put power to it, the fan on the CPU spins, without the motherboard being on yet. The fan is connected to a 4 pin molex. I tried running the powersupply with another computer, but still same problem. But thats not the main problem... It also won't respond to the power button, which i have plugged into the motherboard. So i can't even turn the pc on!

    All jumpers are removed, so right now it's just a dumb psu. It does it both in the car, and in the house when running on my 12V DC Converter.

    Is my powersupply toast??

    Thanks,
    Teebs

    It would help to know what you're trying to power witht e M2 and also how you have it wired....
    Have you looked in the FAQ yet?
    How about the Wiki?

    It's powering a Mini-ITX CL1000, 80GB 2.5" drive and a small 40mm fan. I don't have ingnition startup and shutdown installed yet. So right now it just runs on the cig lighter curcuit in the car.

    ooh.... I'm not gonna say running it via the ciglighter has killed it. But it isn't healthy either.... I'd power it properly first, or else.... Happy BBQ-ing.

    Whats wrong with running on the cig lighter circuit?? It's only temporary till I get my amps and spend the day wiring everything. The cig lighter is just like any other 12V circuit in your car, with a 15amp fuse.

    Cigarette lighters are typically wired for a lot less ameperage than you'd need to pull for the M2ATX.

    My cig lighter is 15 amps. The M2-ATX has a 15 amp fuse, nothing is being overloaded. Infact my DC converter for using the pc in the house is only 5.8amps and has never blown a fuse. So i'm not drawing alot of power.

    Does the gauge of the cig lighter circuit match that of the wires going to the power supply?
