I am seeding from an AMD Ryzen 7 5700G system and with all the peripherals turned off and disconnected, instantaneous load was about 65 watts, until I undervolted it (negative 30, all cores), after which it has been fluctuating around 60 watts.

I'd like to keep seeding indefinitely - of course, my all time share ratio is at around 12 for now - but I'd like to use less energy and spend less money on it - even though the cost difference will be negligible, I guess.

Questions

Do you have any recommendations on what hardware to switch to?
Or any suggestions on further tweaking the power setting's in the BIOS? For now, I'm using AMD's AI solution for undervolting (PBO or Curve Optimizer or whatever it's called?), but there is for instance also the actual overclocking menu, which would force settings on the CPU.
What do you think about putting a single board computer inside my desktop (the chassi is HUGE) and somehow hooking up my four 4TB 2.5 inch torrenting SSDs to it? Possibly still powering them with my desktop's PSU? And running the client (qBittorrent) on the SBC?

I don't know how to do this on AMD boxes but there are tools out there to adjust CPU power limits without undervolting, it uses the chip's built-in ability to throttle itself. I've had to do the reverse on a Dell which limits itself to 0.8GHz on any non-genuine™ power adapter, but in that case I limited the (Intel) CPU's PL2 (long-term power limit) to 25W rather than its spec 35W to save power. It thus keeps itself throttled below 25W consumption by the CPU.

I'm sorry I can't be more helpful with names of tools to try, but I just packed up all my gear to head across town, I'll try to come back and drop some URLs later. I have a little 5750GE box so I'm interested in whatever the solution turns out to be.

Some systems have the CPU power limits editable in the UEFI ("BIOS"). No other tools needed.

Thanks! I never thought of actually downclocking instead of undervolting. No rush! :)
