Will the Ryzen 9 9950X bottleneck the RTX 3060 Ti?

No. At 1440p the RTX 3060 Ti is the limiting part, which is the normal state for a gaming PC. The Ryzen 9 9950X 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 9950X and RTX 3060 Ti?

Sustained gaming load is about 450 W using the RTX 3060 Ti's measured draw. A 650 W unit is the safe choice.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 26% (GPU-bound (normal)). 1440p: GPU-limited 33% (GPU-bound (normal)). 4K: GPU-limited 48% (CPU overkill).

Ryzen 9 9950X + RTX 3060 Ti: bottleneck check

33%

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

CPU GPU

The RTX 3060 Ti is the part working hardest at 1440p, which is what you want. The Ryzen 9 9950X keeps about 33% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	26%	GPU-bound (normal)
1440p	GPU	33%	GPU-bound (normal)
4K	GPU	48%	CPU overkill

The RTX 3060 Ti is the limit at every resolution and by a wide margin at 4K (48%). The Ryzen 9 9950X is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The RTX 3060 Ti measured 205 W average while gaming (221 W highest 20 ms spike, TechPowerUp). With the Ryzen 9 9950X at its TDP of 170 W and about 75 W for the rest of the system, the sustained load is about 450 W. A 650 W unit is the safe choice.
