Will the Ryzen 7 7700X bottleneck the RTX 5080?

No. At 1440p the RTX 5080 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 5080?

Estimated system load is about 565 W. A quality 750 W unit leaves roughly 30% headroom for transient spikes.

Is this pair better at 1080p or 4K?

1080p: CPU-limited 11% (mild CPU bottleneck). 1440p: CPU-limited 4% (balanced). 4K: GPU-limited 18% (balanced).

Ryzen 7 7700X + RTX 5080: bottleneck check

Balanced at 1440p.

CPU GPU

Well matched at 1440p. The Ryzen 7 7700X is the slightly busier part, by about 4%.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	CPU	11%	mild CPU bottleneck
1440p	CPU	4%	balanced
4K	GPU	18%	balanced

This is the classic pattern: at 1080p the Ryzen 7 7700X is the limit (11%), while at 4K the RTX 5080 takes over (18% GPU-limited). If you play at 1080p on a high-refresh monitor, a faster CPU is the upgrade that matters; at 1440p or 4K this pair is already well matched.

Power supply

CPU 105 W + GPU 360 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 565 W. We recommend a 750 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.
