Today I tested whether my 750 PSU (Corsair HX750i) needs urgent replacement for the combination of (undervolted) 13900 + (undervolted) 4090. Running OCCT's PSU test with a 255/253 W CPU power-limit and 418.5 W GPU power-limit says that I can keep the PSU. My CPU runs 40k in CB23 and the GPU over 36k in 3Dmark at these undervolted and power-limited settings.
I also ran Cyberpunk at a full CPU bottleneck, which never happens in practice, and its CPU power usage suggests that no game will ever come close to maxing out CPU power usage. And CP77 seems to be very well multi-threaded already, making good use of the CPU. Switching RT on/off changed fps, but not CPU load.
