Let's have some fun: What's your idle power consumption?
I saw Matt Gadient's post here about his 7 watt system and it made me curious about what everyone's reaching during idle for their rigs. I'm having fun min/maxing while also trying to save a buck but don't think I can get any lower. I'm currently idling at 26 watts running a VM for HA and about 10 dockers (arr's) with the following:
- Intel 13500
- 32gb DDR4
- ASRock H670 board (mATX)
- 1 WD Black 850 2TB NVME
- 6 x 14TB WD Red +'s (spun down)
- 1 PCI X 6 Sata port (asm1166)
- 3 X 120mm fans
- Lian Li SFF SP750 PSU
To accomplish this, I've:
- Enabled all ASPM functions in BIOS (including the ASRock C state unlock in this awesome dudes guide here).
- Turned off turbo boost, disabled audio, WAN, any RGB, etc in BIOS.
- Powertop --auto-tune (all devices are ASPM compatible)
- Governor set to powersave/efficient
- Made sure I don't use any PCI or M.2 slots tied to the CPU lanes.
- VM is assigned to a single E core.
- Measured via Kasa wifi plug (awesome as it charts ever 5 minutes as well).
VM seems to eat up 2-3 watts. Had HA docker previously but the HACS was a pain in the rear without HA OS. If I Top, the Qemux64 (VM) seems to be the largest culprit. At idle, C states are 10-15% in C2, a few % in C3 and C6 and about 5-10% in C8. With array disabled, about 30% in C2 and 30% in C8. My largest event in Powertop is tick_sched_timer with about 1000-2000 events per second. Second largest is about 100, with most in the double digits. Something seems to just keep my package power always going but that could just be Unraid.
I don't think 26 watts is too bad but if anyone has any tips or if you think I'm missing something, let me know. I'm curious what you all are getting so feel free to share your setups!
PS, if I run in Safe Mode, those events seem to go away. So I'm not sure if it's Unraid system or a plugin that's causing that. 1000 events could be normal for all I know?
Added LSI HBA consumption numbers here.
Update: Unraid friends, thanks to everyone chiming in with your rigs. We now have tons of data points for those who come in the future!
