Will the Ryzen 9 5900X bottleneck the GTX 1650?

No. At 1440p the GTX 1650 is the limiting part, which is the normal state for a gaming PC. The Ryzen 9 5900X 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 9 5900X and GTX 1650?

Sustained gaming load is about 244 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 25% (GPU-bound (normal)). 1440p: GPU-limited 32% (GPU-bound (normal)). 4K: GPU-limited 49% (CPU overkill).

Ryzen 9 5900X + GTX 1650: bottleneck check

32%

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 Ryzen 9 5900X keeps about 32% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	25%	GPU-bound (normal)
1440p	GPU	32%	GPU-bound (normal)
4K	GPU	49%	CPU overkill

The GTX 1650 is the limit at every resolution and by a wide margin at 4K (49%). The Ryzen 9 5900X 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 Ryzen 9 5900X at its TDP of 105 W and about 75 W for the rest of the system, the sustained load is about 244 W. A 450 W unit is the safe choice. Details on the GTX 1650 PSU page or try other pairs in the PSU calculator.
