Ryzen 5 5600 + RTX 5080: bottleneck check
CPU-limited at 1440p. Moderate CPU bottleneck.
The Ryzen 5 5600 cannot feed the RTX 5080 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 | 28% | moderate CPU bottleneck |
| 4K | CPU | 9% | balanced |
The Ryzen 5 5600 is the limiting part at every resolution, even at 4K (9%). The RTX 5080 is a much stronger card than this processor can drive — plan a CPU upgrade before spending more on graphics.

Power supply
The RTX 5080 measured 325 W average while gaming (417 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 465 W. A 850 W unit is the safe choice; a good-quality 750 W unit also covers the measured draw. Details on the RTX 5080 PSU page or try other pairs in the PSU calculator.
