Will the Ryzen 7 9700X bottleneck the RX 6900 XT?

No. At 1440p the RX 6900 XT is the limiting part, which is the normal state for a gaming PC. The Ryzen 7 9700X has headroom to spare.

What power supply do I need for a Ryzen 7 9700X and RX 6900 XT?

Estimated system load is about 465 W. A quality 650 W unit leaves roughly 30% headroom for transient spikes.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 11% (balanced). 1440p: GPU-limited 18% (balanced). 4K: GPU-limited 36% (GPU-bound (normal)).

Ryzen 7 9700X + RX 6900 XT: bottleneck check

18%

Balanced at 1440p.

CPU GPU

Well matched at 1440p. The RX 6900 XT is the slightly busier part, by about 18%.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	11%	balanced
1440p	GPU	18%	balanced
4K	GPU	36%	GPU-bound (normal)

The RX 6900 XT is the limiting part at every resolution, which is the healthy direction, and the gap is small enough that neither part is wasted. Upgrade the GPU first when you want more frames.

Power supply

CPU 65 W + GPU 300 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 465 W. We recommend a 650 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.
