Will the Ryzen 7 3700X 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 3700X has headroom to spare.

What power supply do I need for a Ryzen 7 3700X and RTX 3060 Ti?

Estimated system load is about 365 W. A quality 550 W unit leaves roughly 30% headroom for transient spikes.

Is this pair better at 1080p or 4K?

1080p: CPU-limited 18% (mild CPU bottleneck). 1440p: CPU-limited 10% (balanced). 4K: GPU-limited 13% (balanced).

Ryzen 7 3700X + RTX 3060 Ti: bottleneck check

10%

Balanced at 1440p.

CPU GPU

Well matched at 1440p. The Ryzen 7 3700X is the slightly busier part, by about 10%.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	CPU	18%	mild CPU bottleneck
1440p	CPU	10%	balanced
4K	GPU	13%	balanced

This is the classic pattern: at 1080p the Ryzen 7 3700X is the limit (18%), while at 4K the RTX 3060 Ti takes over (13% 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 65 W + GPU 200 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 365 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.
