THE SHORT ANSWER
The Intel Core i5-13400F + AMD Radeon RX 7900 XT pairing is rated Grade S for 1440p gaming with a recommended 650W PSU. Resolution-by-resolution: 1080p: 4% CPU-bound, 1440p: 2% CPU-bound, 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 i5-13400F + AMD Radeon RX 7900 XT pair is 2% CPU-limited at 1440p. That story changes at other resolutions — see the breakdown below. As a build, it grades elite-tier (S).
Expect around 340 FPS in League of Legends and ~92 in the more demanding Starfield — 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.
If you upgrade the cpu, the Intel Core i5-14400F is the closest higher-tier option — see the swap recommendations below for the FPS lift. Plan on at least a 650W 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 Intel Core i5-13400F + AMD Radeon RX 7900 XT.
Can the Intel Core i5-13400F run the AMD Radeon RX 7900 XT?
Yes, the Intel Core i5-13400F will run the AMD Radeon RX 7900 XT, but it's the limiting part — at 1440p the pair is 2% CPU-bound, so the Intel Core i5-13400F can't fully feed the AMD Radeon RX 7900 XT and you'll leave some frames on the table (most noticeable at 1080p and high-refresh). The swap suggestions below list CPUs that unlock more of the AMD Radeon RX 7900 XT.
Will the AMD Radeon RX 7900 XT bottleneck the Intel Core i5-13400F?
The Intel Core i5-13400F + AMD Radeon RX 7900 XT pairing is rated Grade S for 1440p gaming with a recommended 650W PSU. Resolution-by-resolution: 1080p: 4% CPU-bound, 1440p: 2% CPU-bound, 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 i5-13400F + AMD Radeon RX 7900 XT build?
For a Intel Core i5-13400F (65W TDP) paired with a AMD Radeon RX 7900 XT (315W TDP), we recommend a 650W power supply at minimum. This includes 40% headroom over the parts' combined TDP plus 100W for the motherboard, RAM, fans, and storage.
