Will the Core i5-13400F bottleneck the RTX 3060?

No. At 1440p the RTX 3060 is the limiting part, which is the normal state for a gaming PC. The Core i5-13400F 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 i5-13400F and RTX 3060?

Sustained gaming load is about 404 W using the RTX 3060's measured draw. A 550 W unit is the safe choice.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 14% (balanced). 1440p: GPU-limited 22% (GPU-bound (normal)). 4K: GPU-limited 40% (GPU-bound (normal)).

Core i5-13400F + RTX 3060: bottleneck check

22%

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

CPU GPU

The RTX 3060 is the part working hardest at 1440p, which is what you want. The Core i5-13400F keeps about 22% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	14%	balanced
1440p	GPU	22%	GPU-bound (normal)
4K	GPU	40%	GPU-bound (normal)

The RTX 3060 is the limiting part at every resolution, which is the healthy direction, and the gap is small enough that neither part is wasted. Upgrade the GPU first when you want more frames.

Power supply

The RTX 3060 measured 181 W average while gaming (198 W highest 20 ms spike, TechPowerUp). With the Core i5-13400F at its maximum turbo power of 148 W and about 75 W for the rest of the system, the sustained load is about 404 W. A 550 W unit is the safe choice.
