Comment on Planning build: Power efficient headless steam machine, and later upgrade for AI tasks
rambos@lemm.ee 1 year agoJust to add my experience about PSU efficiency: for low power consumption (20-50W) you need PSU rated for minimum power your system needs. So if you are idling at 30W on 700W PSU your efficiency will be super bad because that PSU was made for higher loads and you are using <10%. No matter what PSU class you choose, efficiency will be better if your usage is at 40-70% of PSU max power. This is based on testing multiple desktop ATX PSUs for my small homelab

Definitely.
I forgot to add that it would be necessary not to overdimension the set up. Any extra power is something that needs to be powered.
But with the chosen cpu and GPU there is not a lot of room here.
