I was interested in that some time ago, as I host a datacenter^H^H^H^H^H^H the upper shelf of a cupboard is the place where I self-host.
I bought a wattmeter and plugged it between the UPS and the power socket. In addition to the UPS there is a 7 years old tower computer ("the main server" - without a GPU but without any optimisation either, and a few disks including platter ones), a PoE 8 ports switch, a RPi and a ER-4 Ubiquity router.
I was really surprised that the draw is a consistent 60 W. This is about 100 € per year in France.
