Will the Ryzen 7 5800X3D bottleneck the RTX 2060?

No. At 1440p the RTX 2060 is the limiting part, which is the normal state for a gaming PC. The Ryzen 7 5800X3D has headroom to spare.

What power supply do I need for a Ryzen 7 5800X3D and RTX 2060?

Estimated system load is about 365 W. A quality 550 W unit leaves roughly 30% headroom for transient spikes.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 27% (GPU-bound (normal)). 1440p: GPU-limited 34% (GPU-bound (normal)). 4K: GPU-limited 49% (CPU overkill).

Ryzen 7 5800X3D + RTX 2060: bottleneck check

34%

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

CPU GPU

The RTX 2060 is the part working hardest at 1440p, which is what you want. The Ryzen 7 5800X3D keeps about 34% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	27%	GPU-bound (normal)
1440p	GPU	34%	GPU-bound (normal)
4K	GPU	49%	CPU overkill

The RTX 2060 is the limit at every resolution and by a wide margin at 4K (49%). The Ryzen 7 5800X3D is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

CPU 105 W + GPU 160 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 365 W. We recommend a 550 W unit (80 Plus Gold or better) so transient spikes from the graphics card stay inside the PSU's comfort zone. Try other pairs in the PSU calculator.
