    I was thinking of trying one of these for a new build because of the size. If I needed more power later on for upgrading could 2 of these be run in parallel without problems??

    Subscribed. I've been looking at thees pico supplies to save on space, this one is the highest wattage available. I'm a owner of (2) m2-atx power supplies that still run to this day (2 years later) so I was instantly intrigued when i noticed a m3 was available!

    Couple Q's

    Does the entire PSU plug right into the ATX socket?

    How many Molex connectors does it have?

    What is the wattage available on the 12v rail?

    The instructions should be in the package, no?

    From what I know from M2, it's 1 for power, 1 for swich and 1 for ground.

    so I realized that the owners manual for the M3 was not provided on the product page on our store. I have now uploaded it.

    It should answer all of your questions: http://store.mp3car.com/M3_ATX_125_W..._p/pwr-029.htm

    ok so maybe is not a problem but I tried the "Thump" connection (grey wire) and it will not cut on my amps. I even tried to connect a 30amp sp relay but no go (no enough power to activate the relay). Thats a bummer.
