I dont have a specific goal how low i want to come.
My Server is an i3-10100 with five HDD an one NVMe. I know that the 20-25W on idle (with disks spun down) are good. But i have also read that there are people which manage to run similiar setups at 15W using really pricey platinum PSU's.
But i am really surprised that i didnt find any PSU which is more efficient than my 14 year old and dont cost a whole lot of money.
Nevertheless the PSU is 14 years old so it would be nice to have a goold replacement at hand, in case it dies.
Quite estonishing, maybe some DELL 12V only magic.
