Core i5-12400F + RX 7700 XT: bottleneck check

4%

Balanced at 1440p.

Well matched at 1440p. The RX 7700 XT is the slightly busier part, by about 4%.

This is the classic pattern: at 1080p the Core i5-12400F is the limit (5%), while at 4K the RX 7700 XT 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 RX 7700 XT measured 228 W average while gaming (285 W highest 20 ms spike, TechPowerUp). With the Core i5-12400F at its maximum turbo power of 117 W and about 75 W for the rest of the system, the sustained load is about 420 W. A 750 W unit is the safe choice; a good-quality 650 W unit also covers the measured draw. Details on the RX 7700 XT PSU page or try other pairs in the PSU calculator.
