Core i7-11700K + GTX 1660 Super: bottleneck check
GPU-limited at 1440p. GPU-bound (normal).
The GTX 1660 Super is the part working hardest at 1440p, which is what you want. The Core i7-11700K keeps about 21% in reserve.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 12% | balanced |
| 1440p | GPU | 21% | GPU-bound (normal) |
| 4K | GPU | 40% | GPU-bound (normal) |
The GTX 1660 Super 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 GTX 1660 Super measured 127 W average while gaming (140 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 327 W. A 450 W unit is the safe choice.
