Will the m1 atx work if it isn't connected to a mb? If not, which connector pins need to be shorted?
Not sure what you mean - you mean at all? As in the main motherboard loom is disconnected at the power supply end? I have an M1-ATX and I have the motherboard loom connected but I don't currently use the "Auto ON/OFF" jumper (J6 I believe) to automatically tell the motherboard to power-up/down. Are you referring to this? ATX mboards can be fooled into working by shorting the green wire to one of the black wires (ground).
Yes, I don't want to connect the mb loom at all. So if I connect the loom, it's the same colored wires that i short to fool the m1 atx, into thinking a mb is connected? If so, I should be able to short two of the pins that the loom connects to on the m1 atx, without connecting the loom. I just didn't know if it was required on this power supply, or if it would work without having to short anything.Originally Posted by aiml27
My plan is to purchase this as a secondary ps and use it more like a pol for my cd burner, usb hub and monitor. My main power supply is maxed out with the set-up that I am running.
Well I don't think the M1-ATX is particularly "aware" of the motherboard per-say - in your case you can take whatever power you need from the motherboard output on the M1-ATX, i.e. where you normally connect the motherboard loom into.
I believe the M1-ATX is always powering this - it's just the green wire on the loom that tells your motherboard to start up.
You can find the ATX connector pinouts on the web in loads of places - just go to Google and type in

Sorry, forgot to add that you do of course still need the M1-ATX to have both the +12V and IGN lines powered for this to work !!
You might be able to get the max. current values from your M1-ATX manual for the different outputs.
