Will the Core Ultra 9 285K bottleneck the RTX 5060 Ti?

No. At 1440p the RTX 5060 Ti is the limiting part, which is the normal state for a gaming PC. The Core Ultra 9 285K 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 9 285K and RTX 5060 Ti?

Sustained gaming load is about 491 W using the RTX 5060 Ti's measured draw. A 650 W unit is the safe choice.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 18% (balanced). 1440p: GPU-limited 25% (GPU-bound (normal)). 4K: GPU-limited 42% (CPU overkill).

Core Ultra 9 285K + RTX 5060 Ti: bottleneck check

25%

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

CPU GPU

The RTX 5060 Ti is the part working hardest at 1440p, which is what you want. The Core Ultra 9 285K keeps about 25% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	18%	balanced
1440p	GPU	25%	GPU-bound (normal)
4K	GPU	42%	CPU overkill

The RTX 5060 Ti is the limit at every resolution and by a wide margin at 4K (42%). The Core Ultra 9 285K is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The RTX 5060 Ti measured 166 W average while gaming (217 W highest 20 ms spike, TechPowerUp). With the Core Ultra 9 285K at its maximum turbo power of 250 W and about 75 W for the rest of the system, the sustained load is about 491 W. A 650 W unit is the safe choice.
