My friend has an old Dell XPS missing a power supply and on the motherboard it has both 20 and 24 pin imput sockets. I'm thinking its just like how hdds have molex and sata and you use either/or but not both. I'm thinking at most it will just not turn on if I plug in a 24 pin and leave the 20 pin empty. Safe to try?
I had to ask..... Did you ever get this figured out.. Running into same challenge with a Precision 490 that requires a 24 pin and 20 pin connection through the power supply or so I think.. As that was what was plugged in with the factor power supply..
Any solutions are welcome....
