Roy, You won the prize!
The connection I made was per the "Standard" which caused it to
power up - but do that surging thing.
There was a gray wire at the end of the connector which is
the "Magic" wire. Pulled to ground, the power supply fired up good
and works great!
Thanks a bunch!
Chris
Oh, I don't know what the prize is yet though ;-)

#2) this power supply is from a Dell computer. Even with the
jumper
in the correct position, the best I can get it to do is create
a "Pulse" of output. In other words, if I connect a fan to the
output wires and jumper the "Run" wires, the fan (external one)
will
spin up and then die down and repeat - it won't spin the fan
continuously. The internal fan will not start up at all. Any
ideas
on what might cause this?
Dell for a period of time came out with "ATX" style power supplies
that had a
*radically* different pinout than the standard, and the wire
you're probably
jumpering is not the right one. If I'm remembering right on the
standard
setup the color codes for the wires is green for the one you want
and black
on either side of it for ground. That "power on" signal is pin
14, 13 and
15 are grouinds.
Dell didn't do that with all of their ATX supplies, only for a
period of
time, but if the one you're messing with has different wire
colors I'd worry
about the pinouts. Those will NOT work with a standard MB...
