Well, Tom SSH'ed in tonight and let me know the problem is the molex power supply I'm using.  His advice was:

"just buy the cheapest desktop PSU you can find, you can probably get one
for $20

its very easy to modify to be stand alone and be able to turn on and off
without a motherboard just snip the black and green cable and connect them
wrap in some electrical tape if you got it, you guys got frys out there
right? you can buy one in store or buy one online, you dont need nothing
special the cheapest one you can find will work."

What is everyone else using to power their MMQs?
