Will the Core i5-13600K bottleneck the Arc A750?

No. At 1440p the Arc A750 is the limiting part, which is the normal state for a gaming PC. The Core i5-13600K has headroom to spare.

What power supply do I need for a Core i5-13600K and Arc A750?

Estimated system load is about 506 W. A quality 750 W unit leaves roughly 30% headroom for transient spikes.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 24% (GPU-bound (normal)). 1440p: GPU-limited 31% (GPU-bound (normal)). 4K: GPU-limited 47% (CPU overkill).

Core i5-13600K + Arc A750: bottleneck check

31%

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 Core i5-13600K keeps about 31% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	24%	GPU-bound (normal)
1440p	GPU	31%	GPU-bound (normal)
4K	GPU	47%	CPU overkill

The Arc A750 is the limit at every resolution and by a wide margin at 4K (47%). The Core i5-13600K is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

CPU 181 W + GPU 225 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 506 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.
