Core i9-14900K + GTX 1080 Ti: bottleneck check
GPU-limited at 1440p. GPU-bound (normal).
The GTX 1080 Ti is the part working hardest at 1440p, which is what you want. The Core i9-14900K keeps about 38% in reserve.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 32% | GPU-bound (normal) |
| 1440p | GPU | 38% | GPU-bound (normal) |
| 4K | GPU | 52% | CPU overkill |
The GTX 1080 Ti is the limit at every resolution and by a wide margin at 4K (52%). The Core i9-14900K is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply
CPU 253 W + GPU 250 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 603 W. We recommend a 850 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.
