Core i5-11400F + RTX 5070 Ti: bottleneck check
CPU-limited at 1440p. Moderate CPU bottleneck.
The Core i5-11400F cannot feed the RTX 5070 Ti fast enough at 1440p, so the card sits partly idle in CPU-heavy games.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 33% | moderate CPU bottleneck |
| 1440p | CPU | 27% | moderate CPU bottleneck |
| 4K | CPU | 8% | balanced |
The Core i5-11400F is the limiting part at every resolution, even at 4K (8%). The RTX 5070 Ti is a much stronger card than this processor can drive — plan a CPU upgrade before spending more on graphics.

Power supply
The RTX 5070 Ti measured 287 W average while gaming (348 W highest 20 ms spike, TechPowerUp). With the Core i5-11400F at its TDP of 65 W and about 75 W for the rest of the system, the sustained load is about 427 W. A 750 W unit is the safe choice; a good-quality 650 W unit also covers the measured draw. Details on the RTX 5070 Ti PSU page or try other pairs in the PSU calculator.
