Will the Core i9-13900K bottleneck the RTX 2070 Super?

No. At 1440p the RTX 2070 Super is the limiting part, which is the normal state for a gaming PC. The Core i9-13900K 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 i9-13900K and RTX 2070 Super?

Sustained gaming load is about 539 W using the RTX 2070 Super's measured draw. A 850 W unit is the safe choice.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 29% (GPU-bound (normal)). 1440p: GPU-limited 35% (GPU-bound (normal)). 4K: GPU-limited 50% (CPU overkill).

Core i9-13900K + RTX 2070 Super: bottleneck check

35%

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

CPU GPU

The RTX 2070 Super is the part working hardest at 1440p, which is what you want. The Core i9-13900K keeps about 35% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	29%	GPU-bound (normal)
1440p	GPU	35%	GPU-bound (normal)
4K	GPU	50%	CPU overkill

The RTX 2070 Super is the limit at every resolution and by a wide margin at 4K (50%). The Core i9-13900K is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The RTX 2070 Super measured 211 W average while gaming (220 W peak, TechPowerUp). With the Core i9-13900K at its maximum turbo power of 253 W and about 75 W for the rest of the system, the sustained load is about 539 W. A 850 W unit is the safe choice.
