Use multiple power supplies?

[DonNiggera]

I was thinking, could I plug a 235w power supply to my motherboard, and leave it be... and use a 200w power supply for my cdroms, hard drive, and floppy? And fans and stuff?

You think?

Yes, but good luck finding a case that has places for more than one P/S.

Also, with ATX power supplies you'll have to do some wiring to get them all to turn on with the case switch.

If you are not running a P4 or a TBird 1.2 Ghz it should work....

You might have some problems powering on and off with two powersupplies

Check out the Technick.net under - forums - circuits - "Turnning On Dual PowerS Supplies"
there is a whole lot of info...

Here is a link from the site for the wiring of two PS together

uhmm it's not that hard, all you have to do is connect two pins on the mobo connector in the second psu and just turn it on before you power up your system. I'm not sure which pins you hev to connect but I think it's something like 7 and 8 or 12 and 11. anyway there should be a diagram on the psu. or you can just try connecting pns until it powers up. or if you want it to turn on automatically when your main psu turns on, you can also do it, all you have to do is sodder two wires from the psu's. I'll pm you a diagram when I get home, or you could look it up, I'm sure there are a lot of guides out there.

Simply connect a switch between the green wire and any black wire. When they are connected, the supply will turn on. I'm using this setup right now...
