Replacement PSU for Dell Optiplex 790 MT

[SamathaV]

Hiya, it appears that my PSU is about to give up in the near future, I suppose. The first start-up usually fails (from the state where power is off) under a second due to unexpected power failure. (This is confirmed by S.M.A.R.T. data of SSD.) Second time everything works out and same with restarts.

First I assumed that replacing PSU would be as simple buying something with enough wattage output, suitable physical size and connectors. It seems not to be. Here are the specs of the current PSU. (p. 21, first column) What do I replace it with?

Thanks!

If the connectors are non-standard, you should by an OEM power supply. Ebay has lots of them. Just make sure that the new PSU is powerful enough - maybe that's what killed your current PSU.

I did some browsing before posting here. Apparently not all PSUs fit to every system, even though the connectors are correct and they give out enough wattage? E.g., this youtube-video.

Just search for PSU model, everything should be the same.
