Wow, putting everything in the same units is really informative. Running my 450 watt gpu for a day is approximately equivalent to driving a car 10 miles.
My (admittedly old) gpu+CPU idles around 50-75w.
Ryzen + GPU + 1h of gaming, but 3 screens attached.
still a "desktop computer" - stuff in the browser can spike GPU wattage, but I don't think it will be meaningfully different over several hours of true idle..
My problem is more like: I could measure that, but I'd have to recable everything to have the power meter behind the power strip with just PC + screens... which I will probably do at some point, but it involves redoing 50% of the cables in this room.
