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).

There are cards like that.

But you don't have to buy those cards. I play my games in QHD on a Radeon 6700XT 12GB, which tops out at about 165W.

I can't lie, the idea of needing a 30amp dedicated CB makes me feel happy as a nerd. Makes my power company happier..
