THE SHORT ANSWER
The Intel Core i5-14400F + Intel Arc B570 pairing is rated Grade C for 1440p gaming with a recommended 400W PSU. Resolution-by-resolution: 1080p: 20% GPU-bound, 1440p: 23% GPU-bound, 4K: 23% GPU-bound. 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 i5-14400F + Intel Arc B570 pair is 23% GPU-limited at 1440p. Same pattern at 1080p and 4K. As a build, it grades capable (C).
Expect around 226 FPS in League of Legends and ~52 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.
If you upgrade the gpu, the NVIDIA GeForce RTX 4060 is the closest higher-tier option — see the swap recommendations below for the FPS lift. Plan on at least a 400W PSU — that includes headroom for transient spikes on the Intel Arc B570.
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 i5-14400F + Intel Arc B570.
Can the Intel Core i5-14400F run the Intel Arc B570?
Yes — the Intel Core i5-14400F runs the Intel Arc B570 comfortably. At 1440p the Intel Arc B570 is the limiting part (23% GPU-bound), which is the ideal balance: the Intel Core i5-14400F has headroom to spare, so you get the GPU's full performance.
Will the Intel Arc B570 bottleneck the Intel Core i5-14400F?
The Intel Core i5-14400F + Intel Arc B570 pairing is rated Grade C for 1440p gaming with a recommended 400W PSU. Resolution-by-resolution: 1080p: 20% GPU-bound, 1440p: 23% GPU-bound, 4K: 23% GPU-bound. 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 i5-14400F + Intel Arc B570 build?
For a Intel Core i5-14400F (65W TDP) paired with a Intel Arc B570 (150W TDP), we recommend a 400W power supply at minimum. This includes 40% headroom over the parts' combined TDP plus 100W for the motherboard, RAM, fans, and storage.
