    Yeah server hardware isn’t the most efficient if you want to save power. It’s probably better to get a NUC or something.

    With that said my old Dell PowerEdge R730 only uses around 84 watt (running around 5 VMs that are doing pretty much nothing) The server runs Proxmox and has 128 GB of ram, two Xeon E5-2667 v4 CPUs, 4 old used 1 TB HDDs I bought for cheap, and 4 old used 128 GB SATA SSDs I also bought for cheap (all storage is 2,5 drives).

    All I had to do was change a few BIOS settings to prioritize efficiency over performance. 84 watts is obviously still not great but it’s not that bad.

      Sounds nice, but yes, uses quite a bit of power.

      I should measure mine - I have a Ryzen 5900 (24t, 64MB … some 20k cinebench score) as the main, and a Core 12700 (16+4t, 12MB).
      (And Intel gen 7 and 2 at my patents. All of them proxmoxed.)

      Never ever managed to bottleneck anything on them, not really, but got them super cheap used.

      Buying anything server/enterprise that powerful would cost me a lot of moneys. And prob have two CPUs which doubles a lot of power hungry bits.

        The only reason that I have measured my server is that it has that feature built into the iDRAC. I have been thinking of buying an external power meter for years but have never bothered to do that.

        Luckily I got my server for free from work. It was part of an old SAN so it came with 4 dual 16 Gbit fiber channel cards and 2 dual 10 gigabit ethernet cards. Before I took those out of the server it consumed around 150 watts at idle which is crazy.
