Difficult question to answer as it depends on your hardware setup. My system idles at 54-60W (8 disk drives sleeping, 2 NVMes active, 12700k). About 75-80W if 1-3 disk drives are active. It can bump up to ~140-200W if transcoding. Speaking of transcoding...
Confirming that tonemapping works on the linuxserver/plex container (currently need to be using the "latest" version). Hardware transcoding is now about 95-105W.
