    3M-ATX short circuit?

    I have tested my M3-ATX PSU with the PC several times and it works. But today i was testing again and put the minus on plus and vice verca for a few sec and now when i do it correctly, my MB diode turns on, the PSU turns on for a sec and then clicks and turns off. It does that again and again if the power is still on.

    Have i damaged it or is it something else? The battery is a small 12V.

    If its damaged, can it be saved at least?

    Doubtful.
    Electronics don't like reversed polarity.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.
