Will the Ryzen 9 9950X3D 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 9 9950X3D 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 9 9950X3D and RTX 2060?

Sustained gaming load is about 412 W using the RTX 2060's measured draw. A 550 W unit is the safe choice.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 43% (CPU overkill). 1440p: GPU-limited 48% (CPU overkill). 4K: GPU-limited 60% (CPU overkill).

Ryzen 9 9950X3D + RTX 2060: bottleneck check

48%

GPU-limited at 1440p. CPU overkill.

CPU GPU

The RTX 2060 is the part working hardest at 1440p, which is what you want. The Ryzen 9 9950X3D keeps about 48% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	43%	CPU overkill
1440p	GPU	48%	CPU overkill
4K	GPU	60%	CPU overkill

The RTX 2060 is the limit at every resolution and by a wide margin at 4K (60%). The Ryzen 9 9950X3D is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The RTX 2060 measured 167 W average while gaming (182 W highest 20 ms spike, TechPowerUp). With the Ryzen 9 9950X3D at its TDP of 170 W and about 75 W for the rest of the system, the sustained load is about 412 W. A 550 W unit is the safe choice.
