Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

This seems very suspicious, get a cheap watt metter and test it with that. If it still says 100W I would say there's something wrong in your CPU, motherboard or software. Not necessarily the CPU, can be the motherboard or simply your Linux is set to run the CPU at full clock all the time.
Btw, I have a Ryzen 5 2600 and that thing goes down to 20W or so.
I specifically had to set things up in the BIOS so that it would never enter any efficient power/sleep states. It's a bug in the OS I'm using that was forcing me to do it, otherwise the whole thing would lock up on me.
That said, I have some smart-plugs that do power monitoring. I can try hooking up the nas to one of those just for kicks, it should be accurate enough for this sort of thing.
Edit: Just measured and looks like I was about right: 100W under load and around 80W idle
There is an issue with ryzen and certain PSUs that when it goes to idle it pulls so little power that the psu thinks it's off and kills the power, it can appear as a hang. there should be an option in the bios to change it to "typical power" or named something similar.
Oh interesting, that sound plausible. I'll check out the bios and see if I can find that setting. Thanks!
It's called power supply idle control, worth a test.
This is most likely why you're running at 100W all the time. No need to further measure anything. Reset your BIOS to defaults, update the OS / use Debian and you should be good.
It's not that easy sadly. The entire NAS runs on Unraid and the issue is with that OS. I can't switch without totally restarting from scratch which would be a huge data migration, and a massive PITA configuration-wise.
Eventually I'd be open to switching to something like TrueNas Scale, but for now I need Unraid's unique ability to run a RAID array with differently sized drives
Oh. This kind of issues is why I now run everything on Debian. If you're paying a license you should ask for support and bash them until they fix whatever is wrong with their kernel power management.
Even if you get a new machine you've zero guarantees there wont be any other power management or networking issues with Unraid.
Yeah good point. I've been slowly working to move away from Unraid for those reasons, and have been having fun trying NixOS.
Anyway, I just made a post on the official support forums so hopefully I can get this looked at. Since I initially had the problems many updates have come out, so maybe it's not a thing anymore. I just can't risk testing that for myself!
