Hmmm, if there was then I've not run across one either. Sounds like a Dell
trick, in the same way that, for a while in their desktops they used a
standard ATX connector from the PSU and on the mobo but with some wires
transposed. You could adapt a standard PSU by moving the wires but if you
didn't know about it (and most didn't, it was a standard 20-pin mobo
connector FFS!) you could end up with far bigger problems than just a bad
PSU!
