This is the classic pattern: at 1080p the Core i5-12600K is the limit (4%), while at 4K the RTX 4070 Super takes over (24% GPU-limited). If you play at 1080p on a high-refresh monitor, a faster CPU is the upgrade that matters; at 1440p or 4K this pair is already well matched.

Power supply

The RTX 4070 Super measured 218 W average while gaming (239 W highest 20 ms spike, TechPowerUp). With the Core i5-12600K at its maximum turbo power of 150 W and about 75 W for the rest of the system, the sustained load is about 443 W. A 650 W unit is the safe choice.
