    It'll only see the power supply hooked to the Motherboard, as only one is hooked up to it, but the system as a whole will be receiving the extra power. You'd basically want to hook up your drives and other things to the second supply so your 1st is mainly supplying power to just the motherboard and should have plenty of power for any addon cards (more powerful vid cards), big heatsinks, or whatever.. whatever works best for you

    Another attempt

    I've had this thread bookmarked for a few weeks when I thought that 160W just might not be enough.

    Using Two PSU's

    Also works out cheaper to buy two M2-ATX's than one DSATX and there is more power available.

    Of course if what is contained in that thread above is what you've all been talking about forgive me... when topics turn to electronics my mind tends to wander.

    God damn I feel stupid!

    Pin 14 (the green one) can just be joined to other pin 14, and boom! Instant dual M2's. No need to mess with the on off switch or anything. Just connect them exactly the same ign to ign, const, to const, and ground, to ground.

    It should turn on. Just make sure there is enough load on the rails.

    Ive done this. It works. There is actually quite a few ways to hook them both up. You can run them each standalone with the same timing scheme (as stated right above pin 14 in parellel)(thats what i did) or as mentioned a few posts back, run one as a 'dumb' unit using the switch as power for it. Very easy to do. Just need the correct gauge wire to run 2 of them at the same time if you don't want things to get hot. Really hot.

    Would someone mind making a few diagrams for these options?

    I think it would make a great sticky!

    I think this should be right (if not let me know and I'll make the req changes to all schematics). I've also included some extra bits on how to connect your devices, etc. Let me know what you think...

    The green wire splice is not necessary. The switch basically 'is' the green wire. The rest of the schematic is good. If you want to hook up a power hungry MB, video card, etc its all about how you hook up your devices on the secondary circuit (output). Also if the M1, M2 is in 'dumb' mode you don't need a switch to turn it on. Just give it power on the + and - and it will turn on. Here is a diagram of how a very high power draw computer could be hooked up. This simulates a 480watt power supply. Don't forget the first power supply hooked up to the MotherBoard must have the ATX harness and power switch wire hooked up. The rest of the componets just need the red, black, and yellow from the other M2(1)'s

    Please note this diagram is a POWER SCHEME. It has nothing to do with how data connections are hooked up

    /Edit redid schematic after webmaster's comment
