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
CPU 125 W + GPU 125 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 350 W. We recommend a 550 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.
