Will the Core i7-14700K bottleneck the RX 7600?

No. At 1440p the RX 7600 is the limiting part, which is the normal state for a gaming PC. The Core i7-14700K has headroom to spare. This is a model estimate from performance indexes, not a measured FPS loss.

What power supply do I need for a Core i7-14700K and RX 7600?

Sustained gaming load is about 480 W using the RX 7600's measured draw. A 650 W unit is the safe choice.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 28% (GPU-bound (normal)). 1440p: GPU-limited 35% (GPU-bound (normal)). 4K: GPU-limited 49% (CPU overkill).

Core i7-14700K + RX 7600: bottleneck check

35%

GPU-limited at 1440p. GPU-bound (normal).

CPU GPU

The RX 7600 is the part working hardest at 1440p, which is what you want. The Core i7-14700K keeps about 35% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	28%	GPU-bound (normal)
1440p	GPU	35%	GPU-bound (normal)
4K	GPU	49%	CPU overkill

The RX 7600 is the limit at every resolution and by a wide margin at 4K (49%). The Core i7-14700K is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The RX 7600 measured 152 W average while gaming (186 W highest 20 ms spike, TechPowerUp). With the Core i7-14700K at its maximum turbo power of 253 W and about 75 W for the rest of the system, the sustained load is about 480 W. A 650 W unit is the safe choice.
