Will the Ryzen 7 5700X3D bottleneck the RX 7600?

No. At 1440p the RX 7600 is the limiting part, which is the normal state for a gaming PC. The Ryzen 7 5700X3D has headroom to spare. This is a model estimate from performance indexes, not a measured FPS loss.

What power supply do I need for a Ryzen 7 5700X3D and RX 7600?

Sustained gaming load is about 332 W using the RX 7600's measured draw. A 550 W unit is the safe choice; a good-quality 450 W unit also covers it.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 17% (balanced). 1440p: GPU-limited 24% (GPU-bound (normal)). 4K: GPU-limited 41% (CPU overkill).

Ryzen 7 5700X3D + RX 7600: bottleneck check

24%

GPU-limited at 1440p. GPU-bound (normal).

CPU GPU

The RX 7600 is the part working hardest at 1440p, which is what you want. The Ryzen 7 5700X3D keeps about 24% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	17%	balanced
1440p	GPU	24%	GPU-bound (normal)
4K	GPU	41%	CPU overkill

The RX 7600 is the limit at every resolution and by a wide margin at 4K (41%). The Ryzen 7 5700X3D is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The RX 7600 measured 152 W average while gaming (186 W highest 20 ms spike, TechPowerUp). With the Ryzen 7 5700X3D at a power figure of 105 W and about 75 W for the rest of the system, the sustained load is about 332 W. A 550 W unit is the safe choice; a good-quality 450 W unit also covers the measured draw. Details on the RX 7600 PSU page or try other pairs in the PSU calculator.
