GPU power usage reduction


I got an rtx 2080, and the card is drawing 70W-80W during idle operations.
using nvidia proprietary blob (doh), version 51x (latest released). Power consumption
is shown by nvidia-smi command, same values are pulled by nvtop so I assume those
are accurate.

When the card is under serious load, it takes around 230W-240W, depends on power limit and the computation done.

Windows (also known as M$ SaaS, aka Spyware as a System) consumes around 18W on idle.
Without X/Xorg running - the same. Any suggestions?
