Will the Ryzen 7 7700X bottleneck the RTX 4070 Super?

No. At 1440p the RTX 4070 Super is the limiting part, which is the normal state for a gaming PC. The Ryzen 7 7700X has headroom to spare.

What power supply do I need for a Ryzen 7 7700X and RTX 4070 Super?

Estimated system load is about 425 W. A quality 650 W unit leaves roughly 30% headroom for transient spikes.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 6% (balanced). 1440p: GPU-limited 13% (balanced). 4K: GPU-limited 32% (GPU-bound (normal)).

Ryzen 7 7700X + RTX 4070 Super: bottleneck check

13%

Balanced at 1440p.

CPU GPU

Well matched at 1440p. The RTX 4070 Super is the slightly busier part, by about 13%.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	6%	balanced
1440p	GPU	13%	balanced
4K	GPU	32%	GPU-bound (normal)

The RTX 4070 Super 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 105 W + GPU 220 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 425 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.
