Will the Ryzen 7 5800X 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 7 5800X has headroom to spare.

What power supply do I need for a Ryzen 7 5800X and GTX 1650?

Estimated system load is about 280 W. A quality 450 W unit leaves roughly 30% headroom for transient spikes.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 22% (GPU-bound (normal)). 1440p: GPU-limited 30% (GPU-bound (normal)). 4K: GPU-limited 47% (CPU overkill).

Ryzen 7 5800X + GTX 1650: bottleneck check

30%

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 7 5800X keeps about 30% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	22%	GPU-bound (normal)
1440p	GPU	30%	GPU-bound (normal)
4K	GPU	47%	CPU overkill

The GTX 1650 is the limit at every resolution and by a wide margin at 4K (47%). The Ryzen 7 5800X is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

CPU 105 W + GPU 75 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 280 W. We recommend a 450 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.
