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?

I’ve been using Thermaltake GX2’s. They’re $50 and still maintain a Gold rating. For the marginal difference on an electric bill going from gold to platinum, it would take me 10 years to make up the difference in cost of the PSU.
for what it’s worth I picked up a used HP DL360 gen9 server and it came with dual 80 platinum power supplies, 128gb DDR, and dual Xeon 2680v4 (28c/56t) processors… no HDD but the cost was $150… I actually got the the server with for $100 and I then I got a pair of used processors of ebay for an extra $50…
with a few SAS cables and my 4tb drives from my old server… I migrated everything over to this server running proxmox and I’m hitting 150w average which is less than my previous bare metal devices.
It might not work for everyone, but I’m glad I decided to make the jump to enterprise hardware as I was looking for reliability and reducing my power load overall.
A pair of 2680v4’s certainly didn’t decrease your power usage unless you came from Nehalem’s.
My 2660v4’s in a DL380P G9 idled at 220w. Getting rid of that machine and moving to Alder Lake was the absolute best thing I did for my home server. The new system runs circles around those ancient Xeon’s and consumes less than half of the power. I went from averaging 200kwh/mo with the HPE to ~80kwh/mo. $30/mo savings paid for the entire upgrade to a better platform.
Alder Lake
ok you got me. The 2680s are in the mail still and should be here next week… maybe friday. It currently has dual 2637s but my idle is 90~100w with just proxmox and 5 SSD and 150w running all my services. Once the processors are in we’ll see how it does but since the TDP is less per processor I don’t anticipate a jump in consumption.
Wow didn’t notice how hard it is to get a platinum 500w power supply in 2023… The only one being a Seasonic or Silverstone one for over 200$ (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. 😉
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.
