Can't speak for the most modern ones which I know are worse, but I was pretty surprised when I recently got a smart plug with power monitoring recently to find that my system with a 3080 (though, undervolted slightly), 16-core cpu, way too many peripherals, eight various drives, several small screens and dual monitors, only pulls 600-650W under full load.

I got the plugs to help me choose an appropriate UPS, and I don't need one as powerful as I'd thought I would.

I need to get one of those. I have 5 spinning disks + 1 SSD, though not much else high powered - it's a file server, CPU is at least 8 years old, and GPU (if you can even call it that) is passively cooled... I just replaced my 500W power supply because its fan had died (explains why occasionally I'd come home and find it powered off) and nothing under 650W had enough SATA power connectors, so that's what I ended up with. Curious how overkill it is...

I run Linux on an old gaming PC that I use as a file server / jellyfin server / homeassistant / probably a bunch more I'm forgetting, and that one rarely goes above 50W, lol. Haven't tested it under full load, though.
