    Without the M2, everything works flawlessly. When trying to power with the M2, the green led on the MB goes on for a second and shuts off right away. Safe to assume that the M2 is toast?

    after reading the installation manual again, I realized that the jumpers are set to P4 - 30seconds + 1min AutoLatch - does the led lighting up and turning off right away represent the ON pulse and then it waits 30 seconds before it provides power to motherboard?

    try setting it to p0 mode. standard atx mode. just take off the jumper. and it should turn right on when you flip the switch. i use P1 and it works.

    if not, i'd still check the voltage on your 12v rail. if its under 11.2V, the system won't turn on.

    also, i read somewhere that you need may need to short another two wires on the atx connector on your PSU. pins 8&9. they are the "stay on" wires on some power supplys.

    roflcopter - thanks for the advise. I actually tried that before and still wasn't powering on. After playing around a little more and leaving the P1 setting, the computer powered on and now everything works perfectly.
