Ryzen 5 5600 + GTX 1660 Super: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The GTX 1660 Super is the slightly busier part, by about 18%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 10% | balanced |
| 1440p | GPU | 18% | balanced |
| 4K | GPU | 38% | 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 Ryzen 5 5600 at a power figure of 65 W and about 75 W for the rest of the system, the sustained load is about 267 W. A 450 W unit is the safe choice.
