Peak draw for even a current-gen graphics card is well over 500W. There are rumors that a 4090 will need as much as a 1500W power supply to run it. That's almost a complete 15A circuit just for the PC once you factor in cooling, speakers, monitor etc.
I already have issues where the breaker would pop with my current gaming PC if it fully spins up and I had to get a 20A circuit put in to handle it (mostly because there is more than one computer on the circuit).
Just realized everyone's gonna have to turn their power targets down when running a LAN party. I gave my brother my old 2080ti, something would coil whine when he played Battlefield. We turned the card's power target down until the whine went away. We found at 35%, the whine stopped, and the performance difference was not easily discernable with a basic FPS counter just flying around a MP game.
Opportunity for software that dynamically adjusts CPU and GPU power targets in the middle of various games, learns the game's power/performance profile and whether it's CPU/GPU bottlenecked, and optimizes perf/watt while maintaining a given FPS target?
