Will the Core Ultra 5 245K bottleneck the GTX 1650?

No. At 1440p the GTX 1650 is the limiting part, which is the normal state for a gaming PC. The Core Ultra 5 245K 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 Core Ultra 5 245K and GTX 1650?

Sustained gaming load is about 298 W using the GTX 1650's measured draw. A 450 W unit is the safe choice.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 33% (GPU-bound (normal)). 1440p: GPU-limited 40% (GPU-bound (normal)). 4K: GPU-limited 55% (CPU overkill).

Core Ultra 5 245K + GTX 1650: bottleneck check

40%

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

CPU GPU

The GTX 1650 is the part working hardest at 1440p, which is what you want. The Core Ultra 5 245K keeps about 40% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	33%	GPU-bound (normal)
1440p	GPU	40%	GPU-bound (normal)
4K	GPU	55%	CPU overkill

The GTX 1650 is the limit at every resolution and by a wide margin at 4K (55%). The Core Ultra 5 245K is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The GTX 1650 measured 64 W average while gaming (66 W peak, TechPowerUp). With the Core Ultra 5 245K at its maximum turbo power of 159 W and about 75 W for the rest of the system, the sustained load is about 298 W. A 450 W unit is the safe choice.
