Will the Ryzen 7 7700 bottleneck the RX 9070?

No. At 1440p the RX 9070 is the limiting part, which is the normal state for a gaming PC. The Ryzen 7 7700 has headroom to spare.

What power supply do I need for a Ryzen 7 7700 and RX 9070?

Estimated system load is about 385 W. A quality 550 W unit leaves roughly 30% headroom for transient spikes.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 0% (balanced). 1440p: GPU-limited 8% (balanced). 4K: GPU-limited 28% (GPU-bound (normal)).

Ryzen 7 7700 + RX 9070: bottleneck check

Balanced at 1440p.

CPU GPU

Well matched at 1440p. The RX 9070 is the slightly busier part, by about 8%.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	0%	balanced
1440p	GPU	8%	balanced
4K	GPU	28%	GPU-bound (normal)

The RX 9070 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 220 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 385 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.
