Do you have any additional detail info on whether connecting a standard
ATX PS will damage the Dell boards, or, conversely, whether connecting a
Dell PS will damage standard boards?

Also, do you have any details on why Dell deviated from the ATX standard
20-pin power connector pinouts, or as to the actual pinouts they use?
And, have they deviated from the ATX pinout standard for ALL of their
systems' power supplies?

I remember doing some basic troubleshooting and finding one or more Dell
PS that didn't work on standard ATX boards, and I saw then that there
are some changes on the pinouts - - in particular, I remember that I was
looking for two pins which are grounds (black wires) on standard ATX and
those pins had different colored wires on the Dell unit.  And last week,
I happened to see a Dell PS sitting on workbench where I volunteer, and
someone had written "DELL ONLY" on it.

thanks - - -  JimH.
