Will the Core i5-14600K bottleneck the RTX 5060?

No. At 1440p the RTX 5060 is the limiting part, which is the normal state for a gaming PC. The Core i5-14600K 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 i5-14600K and RTX 5060?

Sustained gaming load is about 391 W using the RTX 5060's measured draw. A 550 W unit is the safe choice.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 20% (balanced). 1440p: GPU-limited 27% (GPU-bound (normal)). 4K: GPU-limited 43% (CPU overkill).

Core i5-14600K + RTX 5060: bottleneck check

27%

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

CPU GPU

The RTX 5060 is the part working hardest at 1440p, which is what you want. The Core i5-14600K keeps about 27% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	20%	balanced
1440p	GPU	27%	GPU-bound (normal)
4K	GPU	43%	CPU overkill

The RTX 5060 is the limit at every resolution and by a wide margin at 4K (43%). The Core i5-14600K is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The RTX 5060 measured 135 W average while gaming (171 W highest 20 ms spike, TechPowerUp). With the Core i5-14600K at its maximum turbo power of 181 W and about 75 W for the rest of the system, the sustained load is about 391 W. A 550 W unit is the safe choice.
