Robert,
most current ATX cases use soft power controls instead of the old
hard switches. There's a pin on the large connector that needs to be
grounded to power the supply up; I don't remember which one. Even if
the supply has a built in switch, the soft power has to be grounded for
it to turn on.

You can find more details on http://www.omnistep.com/~advantag/pwrsup.htm
Instead of soldering the bridge onto the mainboard, I grounded pin 14
(green wire) of the power supply with a short piece of wire in the
connector that plugs into the mainboard (e.g. to adjacent pin 15, black
wire).

Hope this helps,
Hans.

FYI I have a couple of the original NEW AXXION power supplies

If you call ZIPPY (www.zippyusa.com) they could even build one for you

Our price for the PS is $199

Regards

David
