    I think we can include here that the J8 pins HAVE A POLARITY. Plugging the connector in backwards (50% chance!) can cause the M2-ATX to malfunction and be damaged! The board's manual says to check the polarity of the connections carefully, but many of us didn't think a simple switch had a polarity! (We're wrong because it's not a simple switch). Seems this has caused at least half a dozen board failures already, most recently summarized here:

    Are you sure that is correct? It doesnt say anything in the manual that J8 has polarity.
    "The M2-ATX board has several wires that need to be installed in various places.
    When installing, always double check the polarity of your wires with a voltmeter."

    I always though that statement applied to things such as power or ignition wires. I blindly connected my power supply without regards to polarity and everything has been working for a few days. Which way is it +/- on the M2-ATX? On the EPIA M10000 mainboard, it actually gives the polarity of the power switch.

    Which pin is which on J8?

    Someone should link to that resistor swap that that guy did (can't find the thread right now)

    I just compared the specifications listed on the manuals for the M2-ATX and M1-ATX. Perhaps your theory on the polarization of J8 only applies to the M1-ATX? If you look on the specs table for the M1-ATX, the very last row says that J2, J4, J8, J6 are "Polarized Headers." However, on the specs table for the M2-ATX, this row has been removed. Maybe they redesigned the on/off header switch for the M2-ATX?

    i dunno if this is true or not but it would completely explain why my last one died when connected correctly.

    and for my FAQ contribution here is the timing chart listing all available times (more than the listed times in the instructions)

    Why was I told (in another thread) that these power supplies came with the 4-pin, square mainboard aux. power plug? (See image)
    Product info says nothing of this....
    Can it be spliced in? Anyone know the pin-outs? Is there a female plug onboard that supports this plug layout?



    And what is the difference between the two M2's, the base and the HV model? Can't find any documentation on that either!

    Mine didnt come with the 4 pin plug..I think it is an addon that you buy separate. You can slice into it if you need +12 for some reason. Yellow is +12v, black is ground. You can just make the part yourself if you have the connector head.

    I dont know why the HV version is cheaper than the normal version. The only difference seems to be that the HV accepts up to 32v input, whereas the normal version accepts 24.

    My M2-ATX does indeed have that 4pin P4 style connector in addition to the normal ATX 20pin.
