Core i7-14700K + RTX 5070: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The RTX 5070 is the slightly busier part, by about 19%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 12% | balanced |
| 1440p | GPU | 19% | balanced |
| 4K | GPU | 36% | GPU-bound (normal) |
The RTX 5070 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 5070 measured 229 W average while gaming (299 W highest 20 ms spike, TechPowerUp). With the Core i7-14700K at its maximum turbo power of 253 W and about 75 W for the rest of the system, the sustained load is about 557 W. A 750 W unit is the safe choice.
