I aim to build a new homeserver lately.

Upon researching I found the RM550X by Corsair as a power efficient option under low loads.

The sad part is, that its available nowhere.

Does someone know a valid alternative, that does not cost more than the whole build?

Wow didn't notice how hard it is to get a platinum 500w power supply in 2023.. The only one being a Seasonic or Silverstone one for over 200$ (CAD).

Maybe these one?

(Last I checked EVGA branded PSU are Seasonic, been using those for a decade, no issues.)

Also a good brand.

P.S. You never mentioned the cost of your build. ๐Ÿ˜‰

The cost will be at about 400 euros with a Celeron CPU, if the PSU is not 200 Euros alone :D

I aim for maximum efficiency as electricity is pretty expensive in Europe and a replacement for my Zimaboard, which will be used for testing then, because I want to switch from my old Synology to TrueNAS Scale.

The goal is to get an idle power draw of 10-20W (HDDs excluded)

Well getting a better rated PSU for a higher price might help in the long run, you will have to do the math although going with the efficiency of Platinum versus Gold its not a lot.

Europe Electricity is still around 43 cent/KWH?

Its around 30 cent currently cause I have a good contract.

During summer everything is fine cause my photovoltaic system produces almost all of the energy needed.

Have to go more detailed into planning there. Maybe a good Gold+ is the key here.
