[SOLVED] Replacement PSU for Optiplex 790

[Evie_da_Kitsune]

I need to replace the PSU and im not sure which PSUs will fit in the case it has a RX 580 in it and a I-5 2400 so im trying to get a 250-500w PSU. It's uses the regular tower case.

You need a good, solid 500w PSU for the RX580.

With your case, I believe you can actually install a standard ATX PSU and not have to use one of the Dell units.

Something like this will meet your needs. Of course, better options are available.
