Will the Ryzen 7 5700X3D bottleneck the RTX 3060?

No. At 1440p the RTX 3060 is the limiting part, which is the normal state for a gaming PC. The Ryzen 7 5700X3D 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 Ryzen 7 5700X3D and RTX 3060?

Sustained gaming load is about 361 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 19% (balanced). 1440p: GPU-limited 26% (GPU-bound (normal)). 4K: GPU-limited 43% (CPU overkill).

Ryzen 7 5700X3D + RTX 3060: bottleneck check

26%

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 Ryzen 7 5700X3D keeps about 26% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	19%	balanced
1440p	GPU	26%	GPU-bound (normal)
4K	GPU	43%	CPU overkill

The RTX 3060 is the limit at every resolution and by a wide margin at 4K (43%). The Ryzen 7 5700X3D is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The RTX 3060 measured 181 W average while gaming (198 W highest 20 ms spike, TechPowerUp). With the Ryzen 7 5700X3D at a power figure of 105 W and about 75 W for the rest of the system, the sustained load is about 361 W. A 550 W unit is the safe choice.
