Core i7-12700K + RTX 4070 Ti: bottleneck check

5%

Balanced at 1440p.

Well matched at 1440p. The RTX 4070 Ti is the slightly busier part, by about 5%.

This is the classic pattern: at 1080p the Core i7-12700K is the limit (3%), while at 4K the RTX 4070 Ti takes over (25% 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 Ti measured 273 W average while gaming (326 W highest 20 ms spike, TechPowerUp). With the Core i7-12700K at its maximum turbo power of 190 W and about 75 W for the rest of the system, the sustained load is about 538 W. A 750 W unit is the safe choice.
