Will the Ryzen 7 9800X3D 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 7 9800X3D has headroom to spare.

What power supply do I need for a Ryzen 7 9800X3D and RTX 3060 Ti?

Estimated system load is about 420 W. A quality 550 W unit leaves roughly 30% headroom for transient spikes.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 36% (GPU-bound (normal)). 1440p: GPU-limited 42% (CPU overkill). 4K: GPU-limited 55% (CPU overkill).

Ryzen 7 9800X3D + RTX 3060 Ti: bottleneck check

42%

GPU-limited at 1440p. CPU overkill.

CPU GPU

The RTX 3060 Ti is the part working hardest at 1440p, which is what you want. The Ryzen 7 9800X3D keeps about 42% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	36%	GPU-bound (normal)
1440p	GPU	42%	CPU overkill
4K	GPU	55%	CPU overkill

The RTX 3060 Ti is the limit at every resolution and by a wide margin at 4K (55%). The Ryzen 7 9800X3D is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

CPU 120 W + GPU 200 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 420 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.
