Ryzen 5 7600X + RTX 4070: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The RTX 4070 is the slightly busier part, by about 15%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 8% | balanced |
| 1440p | GPU | 15% | balanced |
| 4K | GPU | 34% | GPU-bound (normal) |
The RTX 4070 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 4070 measured 201 W average while gaming (235 W highest 20 ms spike, TechPowerUp). With the Ryzen 5 7600X at its TDP of 105 W and about 75 W for the rest of the system, the sustained load is about 381 W. A 650 W unit is the safe choice; a good-quality 550 W unit also covers the measured draw. Details on the RTX 4070 PSU page or try other pairs in the PSU calculator.
