THE SHORT ANSWER
The AMD Ryzen 9 5950X + AMD Radeon RX 7900 XT pairing is rated Grade S for 1440p gaming with a recommended 700W PSU. Resolution-by-resolution: 1080p: 3% CPU-bound, 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 AMD Ryzen 9 5950X + AMD Radeon RX 7900 XT pair is well-balanced at 1440p gaming. That story changes at other resolutions — see the breakdown below. As a build, it grades elite-tier (S).
Expect around 351 FPS in League of Legends and ~95 in the more demanding Hogwarts Legacy — 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 700W PSU — that includes headroom for transient spikes on the AMD Radeon RX 7900 XT.
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 AMD Ryzen 9 5950X + AMD Radeon RX 7900 XT.
Can the AMD Ryzen 9 5950X run the AMD Radeon RX 7900 XT?
Yes — the AMD Ryzen 9 5950X runs the AMD Radeon RX 7900 XT very well. At 1440p the two are well-balanced (grade S), 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 7900 XT bottleneck the AMD Ryzen 9 5950X?
The AMD Ryzen 9 5950X + AMD Radeon RX 7900 XT pairing is rated Grade S for 1440p gaming with a recommended 700W PSU. Resolution-by-resolution: 1080p: 3% CPU-bound, 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 AMD Ryzen 9 5950X + AMD Radeon RX 7900 XT build?
For a AMD Ryzen 9 5950X (105W TDP) paired with a AMD Radeon RX 7900 XT (315W TDP), we recommend a 700W power supply at minimum. This includes 40% headroom over the parts' combined TDP plus 100W for the motherboard, RAM, fans, and storage.
