THE SHORT ANSWER
The AMD Ryzen 9 9900X + Intel Arc A750 pairing is rated Grade B for 1440p gaming with a recommended 650W PSU. Resolution-by-resolution: 1080p: 19% GPU-bound, 1440p: 25% GPU-bound, 4K: 28% 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 AMD Ryzen 9 9900X + Intel Arc A750 pair is 25% GPU-limited at 1440p. Same pattern at 1080p and 4K. As a build, it grades solid mid-range (B).
Expect around 290 FPS in League of Legends and ~66 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 AMD Radeon RX 6800 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 Intel Arc A750.
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 9900X + Intel Arc A750.
Can the AMD Ryzen 9 9900X run the Intel Arc A750?
Yes — the AMD Ryzen 9 9900X runs the Intel Arc A750 comfortably. At 1440p the Intel Arc A750 is the limiting part (25% GPU-bound), which is the ideal balance: the AMD Ryzen 9 9900X has headroom to spare, so you get the GPU's full performance.
Will the Intel Arc A750 bottleneck the AMD Ryzen 9 9900X?
The AMD Ryzen 9 9900X + Intel Arc A750 pairing is rated Grade B for 1440p gaming with a recommended 650W PSU. Resolution-by-resolution: 1080p: 19% GPU-bound, 1440p: 25% GPU-bound, 4K: 28% 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 AMD Ryzen 9 9900X + Intel Arc A750 build?
For a AMD Ryzen 9 9900X (120W TDP) paired with a Intel Arc A750 (225W 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.
