Core i9-12900K + RTX 3070 Ti: bottleneck check
GPU-limited at 1440p. GPU-bound (normal).
The RTX 3070 Ti is the part working hardest at 1440p, which is what you want. The Core i9-12900K keeps about 21% in reserve.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 14% | balanced |
| 1440p | GPU | 21% | GPU-bound (normal) |
| 4K | GPU | 38% | GPU-bound (normal) |
The RTX 3070 Ti is the limiting part at every resolution, which is the healthy direction, and the gap is small enough that neither part is wasted. Upgrade the GPU first when you want more frames.

Power supply
CPU 241 W + GPU 290 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 631 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.
