I'd usually buy something like a Seasonic Gold PSU for any new PC. But today I'm helping my brother's kid upgrade his gaming PC - which is a prebuilt that has a GameMax RPG 700W Rampage PSU 80 Plus Bronze. The PC hasn't been used much at all, so the PSU is practically new. I'm wondering if it's really worth changing it. The PC spec is Radeon RX 6600 XT + i7 12700K @ no overclock.
Also the prebuilt had a Gigabyte H610M S2H V2 DDR4 motherboard, which has no radiators on the VRM. It used to run fine with an i3-12100, but I wonder how it's going to work with an i7-12700K. Is it going to just limit the amount of power the CPU gets when the VRM elements heat up to their limit? The CPU has a Noctua tower cooler, so not much air flow over the VRM.
