Got a device which shows how many watts any electrical item is using by plugging it into it.

My PC under heavy load uses about 275watts with the screen off, and about 320watts with the screen on.
That also includes the speakers, mouse, keyboard etc
 
Just did a few tests, and I get 50W when idle, 80W with light load*, 180W with full CPU load (IBT), 300W when gaming, 460W under full stress test (FurMark + IBT). Measured with a basic plug-in AC power monitor.

My system consists of a 5950X, X570 motherboard, Radeon VII, 80+ Platinum PSU, two NVME drives, mouse, and keyboard. Everything stock except the GPU, which is undervolted. Monitors excluded from measurements.

* This is quite a bit worse than my old system with an 1800X, which would use only 60W under light load. The 5950X goes shooting up to 80W or more if I so much as move the mouse.
