Will the Core i9-14900K bottleneck the RTX 4060 Ti?

No. At 1440p the RTX 4060 Ti is the limiting part, which is the normal state for a gaming PC. The Core i9-14900K 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 i9-14900K and RTX 4060 Ti?

Sustained gaming load is about 480 W using the RTX 4060 Ti's measured draw. A 650 W unit is the safe choice.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 25% (GPU-bound (normal)). 1440p: GPU-limited 31% (GPU-bound (normal)). 4K: GPU-limited 47% (CPU overkill).

Core i9-14900K + RTX 4060 Ti: bottleneck check

31%

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

CPU GPU

The RTX 4060 Ti is the part working hardest at 1440p, which is what you want. The Core i9-14900K keeps about 31% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	25%	GPU-bound (normal)
1440p	GPU	31%	GPU-bound (normal)
4K	GPU	47%	CPU overkill

The RTX 4060 Ti is the limit at every resolution and by a wide margin at 4K (47%). The Core i9-14900K is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The RTX 4060 Ti measured 152 W average while gaming (169 W highest 20 ms spike, TechPowerUp). With the Core i9-14900K 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.
