    Yup.... It is a buck / boost topology. So it can produce 19V if you have V(IN) below or above 19V.

    So if V(In) is 12V, you can have 19V output.

    You can steal 12V from a regular PSU (Yellow wire).
    To turn on a PSU (without a PC), just ground the PS_ON wire.

    That could be the problem. If you want external switch, just conencted it to J6/J8, don't get ground involved here.

    During standby, if voltage dips below 11.2V for more than 1minute, it will shut down in order to prevent over-discharge.

    Not to worry about wire gauge. M1-ATX works from 6-24V.
    So if you drop a volt here or there, it's OK.
