Core i5-12600K + Arc A770: bottleneck check
GPU-limited at 1440p. GPU-bound (normal).
The Arc A770 is the part working hardest at 1440p, which is what you want. The Core i5-12600K keeps about 23% in reserve.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 15% | balanced |
| 1440p | GPU | 23% | GPU-bound (normal) |
| 4K | GPU | 40% | GPU-bound (normal) |
The Arc A770 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 150 W + GPU 225 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 475 W. We recommend a 650 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.
