Any help appreciated,
I've got a Dell Dimension XPS P133c (purchased in December of '95)
with a bad power supply, I think. One night the computer was working
fine and the next morning nothing worked, I mean nothing. I verified
power was being supplied to the back of the unit, but it was not
getting to anything within the unit, not even the power supply fan.
I removed the power supply, thinking that I'd find someone in town
where a new (or used) one could be purchased. The supply looks very
much like an ATX type, single 20 pin connector to the mother board
and various power cables for peripherals. There is no on/off switch
on the unit, but is remotely switched through the mother board. The
problem is it only supplies +/- 5 volts and +/- 12 volts. There is a
5 volt to 3.3 volt converter on the mother board to supply the cpu
and other parts.
The question(s), does anyone know the pinout values for this supply
and/or know if a standard ATX type of supply (that does provide 3.3
volts) will work for this computer.
I've, already, looked through Dell's web site and talked (several
times) with Dell service technicians for this information without
success. The tech said the connector is standard ATX so any standard
ATX supply will work, but in the same breath said they will not be
responsible for any adverse reaction the supply should cause any of
the components. It took this to mean, it should work, but we don't
know for sure and if it doesn't too bad.
Thanks for any help you can provide,
Bill
