Ryzen 9 5900X + RTX 3060: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The RTX 3060 is the slightly busier part, by about 19%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 11% | balanced |
| 1440p | GPU | 19% | balanced |
| 4K | GPU | 37% | GPU-bound (normal) |
The RTX 3060 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 RTX 3060 measured 181 W average while gaming (198 W highest 20 ms spike, TechPowerUp). With the Ryzen 9 5900X at its TDP of 105 W and about 75 W for the rest of the system, the sustained load is about 361 W. A 550 W unit is the safe choice.
