^ What Anonymous Freak said. Not because of any grudge against Dell for being aholes with an industry standard, but because I can't be bothered wading through the interwebs trying to find documentation for a specific Dell PS when there are standards compliant ATX power supplies of all shapes and sizes free for the taking. It's prioritising my time, not waging some futile war.

But if this supply suits your needs for modding, go for it. Just be sure you check and record the actual supply voltages on each line before proceeding.
