-> Years ago in the days of the "AT" PSs, I wired a cigarette
lighter into one of
-> the blank front panels on one of my dealer's 'display systems' with a 200W PS. 
-> It worked great, and caught a few comments, maybe a customer or two.  At least
-> a few people asked questions, that was a first step!

-> When the system became an ATX with a 250W PS, my dealer had me move the lighter
-> to the new system.  Attempting to use it there ALWAYS caused a system shutdown,
-> then we had to wait five minutes before the PS would turn on again.  The
-> lighter was disconnected, and left as a conversation piece after that.

-> Either the ATX 250W didn't have the 'guts' of the AT 200W, or the ATX had a
-> quicker overload sensor.  Never tried it since...   :-((

 Becasue of the Turn on circuit of the ATX power supply I suspect it is
shutting down becasue it sees too much voltage droop. Although the 5
minute wait leans toward a Thermal Overload.
