That seem a bit high. Are you running a graphics heavy desktop environment?

I'm currently browsing on one monitor and having a twitch stream with GPU accelerated decoding on another, and nvidia-smi reports 49 W for my 3080. Nvidia 525 drivers & Fluxbox as window manager.

Using an AMD 5950X CPU, currently with powersave governor, my PSU reports a total power usage of 120 W.
