If I replace my Dell XPS 710 power supply will I have to go to Dell to replace it? At one time Dell had a special (non-standard ATX) motherboard and power supply made only for them so that the voltages and pin-outs from standard ATX motherboards and power supplies would not work with Dell products.  I don't want to take the chance of frying my system instead of fixing it.

   I would think that the power supply is a standard power supply.  I would suggest going to the computer repair shop (or wherever you would buy the power supply) and asking them.  Then if they say, yes, take the power supply out and take it in with you when you go to buy a new one and compare the new and old one.
