THE SHORT ANSWER
The Intel Core i5-11400F + AMD Radeon RX 6800 pairing is rated Grade B for 1440p gaming with a recommended 600W PSU. Resolution-by-resolution: 1080p: balanced, 1440p: balanced, 4K: balanced. CPU and GPU bottleneck verdicts depend on resolution — a pairing that is CPU-bound at 1080p is often perfectly balanced at 4K because the GPU does more work per frame as pixel count increases.

Plain-English breakdown.
What this pairing actually means when you sit down to play.
The Intel Core i5-11400F + AMD Radeon RX 6800 pair is well-balanced at 1440p gaming. Stays balanced at 1080p and 4K, too. As a build, it grades solid mid-range (B).
Expect around 231 FPS in League of Legends and ~60 in the more demanding Alan Wake 2 — both at 1440p with high or ultra presets. Resolution matters more than most calculators show — the same parts give different verdicts at 1080p, 1440p, and 4K because GPU work scales with pixel count while CPU work is roughly fixed per frame.
Both parts pull their weight; the highest-leverage next upgrade is to a fully higher tier rather than swapping one side. Plan on at least a 600W PSU — that includes headroom for transient spikes on the AMD Radeon RX 6800.
The same pair gives a different answer at 1080p, 1440p, and 4K.
Higher resolutions push work onto the GPU — watch the balance shift.

Common questions.
Straight answers for the Intel Core i5-11400F + AMD Radeon RX 6800.
Can the Intel Core i5-11400F run the AMD Radeon RX 6800?
Yes — the Intel Core i5-11400F runs the AMD Radeon RX 6800 very well. At 1440p the two are well-balanced (grade B), so neither part meaningfully holds the other back and you get close to the full performance both are capable of.
Will the AMD Radeon RX 6800 bottleneck the Intel Core i5-11400F?
The Intel Core i5-11400F + AMD Radeon RX 6800 pairing is rated Grade B for 1440p gaming with a recommended 600W PSU. Resolution-by-resolution: 1080p: balanced, 1440p: balanced, 4K: balanced. CPU and GPU bottleneck verdicts depend on resolution — a pairing that is CPU-bound at 1080p is often perfectly balanced at 4K because the GPU does more work per frame as pixel count increases.
What PSU do I need for a Intel Core i5-11400F + AMD Radeon RX 6800 build?
For a Intel Core i5-11400F (65W TDP) paired with a AMD Radeon RX 6800 (250W TDP), we recommend a 600W power supply at minimum. This includes 40% headroom over the parts' combined TDP plus 100W for the motherboard, RAM, fans, and storage.
