Will the Ryzen 5 7600X bottleneck the Arc A750?

No. At 1440p the Arc A750 is the limiting part, which is the normal state for a gaming PC. The Ryzen 5 7600X 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 5 7600X and Arc A750?

Sustained gaming load is about 383 W using the Arc A750's measured draw. A 550 W unit is the safe choice.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 23% (GPU-bound (normal)). 1440p: GPU-limited 30% (GPU-bound (normal)). 4K: GPU-limited 46% (CPU overkill).

Ryzen 5 7600X + Arc A750: bottleneck check

30%

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

CPU GPU

The Arc A750 is the part working hardest at 1440p, which is what you want. The Ryzen 5 7600X keeps about 30% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	23%	GPU-bound (normal)
1440p	GPU	30%	GPU-bound (normal)
4K	GPU	46%	CPU overkill

The Arc A750 is the limit at every resolution and by a wide margin at 4K (46%). The Ryzen 5 7600X is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The Arc A750 measured 203 W average while gaming (255 W highest 20 ms spike, TechPowerUp). With the Ryzen 5 7600X at its TDP of 105 W and about 75 W for the rest of the system, the sustained load is about 383 W. A 550 W unit is the safe choice.
