Strange... Is the power really THAT great? I get it, there are many pixels in a 4K monitor, but holy cow! If your GPU is taking in 110 W at 10% load, then it is capable of around 1 kW - that's like having a space heater for a PC. In fact, the TUF 3080 specs state a consumption peaking at around 350 W, which I assume is 100% load. The measurement may be skewed, maybe Chrome uses some CPU power for rendering instead? Can you measure the power independently of SW utilities, using a Kill-a-Watt-like device?

10% GPU-load are in this case 110W, same 110W can be as well 70% load at 1000Mhz or 70% @1800, 850mV 260-375W etcpp. some games (War Thunder) are running below 100W maxed out @4k

110W on YT are way to much, period must be a mistake, a huge one
