multiple power supplies

[bpoling]

If I wanted to use 2 power supplies, 1 for the 4 drive raid plus the backup HD, and 1 for mb etc, how would the ps not plugged into the mb know to turn on and off?

You could probably connect two wires on the ATX-mobo connector to keep it "always on" and just use the switch on back of the PS to turn it off and on. I'm sure there's diagrams online somewhere, I'm too lazy to dig them up now.
