I've been having a frustrating issue where my room's power cuts out when I try playing graphically intensive games like Cyberpunk 2077. It seems to happen only during high settings gameplay. Currently, I'm using a 1200W power supply with a GeForce 4090 RTX, Intel i9, and 64GB of RAM on Windows. Is there a way to resolve this, or am I stuck playing on lower settings?

This is more about your home's electrical layout than the PC itself. Check if you have other devices plugged into the same breaker that could be causing the outage. It might be worth moving your setup to a different circuit if possible.
A simple fix is to figure out what other high-demand devices are on the same breaker. Moving them to different outlets can prevent your PC from tripping the fuse. Also, flipping the breaker and checking what else goes off can give you clues.
It’s a common issue with high-powered systems. It shouldn’t really cut power, but if other appliances are also running on that fuse, it makes sense. Try to minimize what’s plugged in or look for other outlets for those devices.
It sounds like you're overloading the circuit breaker in your room. If too many devices are connected to the same circuit, it can trip when your PC demands a lot of power. You might be able to improve efficiency by undervolting your CPU and GPU, but ideally, check what else is on that circuit.
Have you tried adjusting settings? Download MSI Afterburner and reduce the power limit on your 4090 to around 90%. It might help in the short term until you can find a better long-term solution with your home's wiring.
True, if you're using a GFCI breaker, some power supplies can accidentally trip it. I've had issues with GFCI circuits too. If your PSU trips it regularly, consider switching to a different brand or maybe relocating to a non-GFCI circuit.
