Core i9-14900K + RTX 4080 Super: bottleneck check
Balanced at 1440p.
Well matched at 1440p. The RTX 4080 Super is the slightly busier part, by about 10%.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 3% | balanced |
| 1440p | GPU | 10% | balanced |
| 4K | GPU | 29% | GPU-bound (normal) |
The RTX 4080 Super 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
CPU 253 W + GPU 320 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 673 W. We recommend a 1000 W unit (80 Plus Gold or better) so transient spikes from the graphics card stay inside the PSU's comfort zone. Try other pairs in the PSU calculator.
