    Sure, I do it.

    On the ATX connector of the PSU, short the green wire to one of the black ones. The green wire is the soft on wire, and the black ones are the common ones. That'll mean the PSU is on as long as it has power.

    There are more complex ways involving relays and such, so you can tie it to turn on only when the first PSU is on, but what's the point I say "Just turn the plug off at the wall."

    You could also create a switch that you can turn on/off.

    True, lol.

    Get one of those military style toggle switches with the red cover over the top of them!
