Dell Optiplex 3020 MT PSU upgrade?

[Urahara-shoten]

Hi, I hope you could help me. I am looking at possibly buying a Dell Optiplex 3020 MT and I would Like to upgrade the PSU. My Question is would a Seasonic S12 ii 620 Watt PSU be compatible with the Dell Optiplex
3020 MT?

Thanks

The Optiplex 3020 has a proprietary 8 pin MB connector instead of the 24 pin ATX thet a PSU will have. All of the minor Voltages are converted on the MB itself. There are adapters for it.

Another option would be the Dell 365W XE2 Mini Tower PSU which could run up to a GTX1060. Probably a base clocked 150W GTX1070 also. It has an 8 pin MB, a 6 pin PCIe, and a 4 pin CPU and I think that's all.
