Core i7-11700K + Arc A770: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The Arc A770 is the slightly busier part, by about 10%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 1% | balanced |
| 1440p | GPU | 10% | balanced |
| 4K | GPU | 31% | 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
The Arc A770 measured 232 W average while gaming (282 W highest 20 ms spike, TechPowerUp). With the Core i7-11700K at its TDP of 125 W and about 75 W for the rest of the system, the sustained load is about 432 W. A 550 W unit is the safe choice.
