I’m in the process of getting my Home Assistant environment up and running, and decided to run a test: it turns out that my gaming PC (custom 5800X3D/7900XTX build) uses more power just sitting idle, than both of my storage freezers combined.

Background: In addition to some other things, I bought two “Eightree” brand Zigbee-compatible plugs to see how they fare. One is monitoring the power usage of both freezers on a power strip (don’t worry, it’s a heavy duty strip meant for this), and the other is measuring the usage of my entire desktop setup (including monitors and the HA server itself, a Lenovo M710q).

After monitoring these for a couple days, I decided that I will shut off my PC unless I’m actively using it. It’s not a server, but it does have WOL capability, so if I absolutely need to get into it remotely, it won’t be an issue.

Pretty fascinating stuff, and now my wife is completely on board as well; she wants to put a plug on her iMac to see what it draws, as she uses it to hold her cross-stitch files and other things.

      FYI - the cluster is pulling 115-140 watts.

      • 1x Mac mini 2014, running OMV as a dedicated NAS (i5-4308U, 16GB RAM)
      • 4-bay Sabrent DS-SC4B, attached to Mac mini (3x 4TB WD Reds in RAID5, 1x 4TB WD Black as hot spare)
      • 1x 8TB WD backup drive (it’s something)
      • 2x HP Elitedesk 800 G3 mini (or G4, don’t remember), both running Proxmox (i7-7700T, 32GB RAM each)
      • 1x Dell Optiplex 7050 SFF running Proxmox (i7-7700, 32GB RAM)

      All running multiple VMs (Docker and other) and LXC containers.

      I’m impressed, honestly. I was expecting 200+ watts minimum. It’ll be interesting to see the spikes as it’s used over time. I am going to move the HA server (Lenovo M710q running HAOS on a Pentium G4560T & 4GB RAM) down to the cluster soon, as it’s sitting on my desk at the moment…

        I’m surprised! Seems like it should be more, but I haven’t done any wattage calculations in a while, so maybe power efficiency really has gotten that much better.

        Do you know if the drives were spun up or down at the time? I know idle vs. active makes a difference, but if they were spun down entirely, that’s kind of cheating.

          I watched as everything booted, didn’t pull much more than 150 watts. But it’ll be interesting to see how it goes over time.
