Will the Ryzen 9 9900X bottleneck the RTX 3050?

No. At 1440p the RTX 3050 is the limiting part, which is the normal state for a gaming PC. The Ryzen 9 9900X 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 9900X and RTX 3050?

Sustained gaming load is about 328 W using the RTX 3050's measured draw. A 550 W unit is the safe choice; a good-quality 450 W unit also covers it.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 35% (GPU-bound (normal)). 1440p: GPU-limited 42% (CPU overkill). 4K: GPU-limited 55% (CPU overkill).

Ryzen 9 9900X + RTX 3050: bottleneck check

42%

GPU-limited at 1440p. CPU overkill.

CPU GPU

The RTX 3050 is the part working hardest at 1440p, which is what you want. The Ryzen 9 9900X keeps about 42% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	35%	GPU-bound (normal)
1440p	GPU	42%	CPU overkill
4K	GPU	55%	CPU overkill

The RTX 3050 is the limit at every resolution and by a wide margin at 4K (55%). The Ryzen 9 9900X is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The RTX 3050 measured 133 W average while gaming (149 W highest 20 ms spike, TechPowerUp). With the Ryzen 9 9900X at its TDP of 120 W and about 75 W for the rest of the system, the sustained load is about 328 W. A 550 W unit is the safe choice; a good-quality 450 W unit also covers the measured draw. Details on the RTX 3050 PSU page or try other pairs in the PSU calculator.
