THE SHORT ANSWER
The Intel Core i5-12600K + AMD Radeon RX 6700 XT pairing is rated Grade B for 1440p gaming with a recommended 650W PSU. Resolution-by-resolution: 1080p: 19% GPU-bound, 1440p: 22% GPU-bound, 4K: 20% 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 i5-12600K + AMD Radeon RX 6700 XT pair is 22% GPU-limited at 1440p. Same pattern at 1080p and 4K. As a build, it grades solid mid-range (B).
Expect around 243 FPS in League of Legends and ~56 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 6750 XT 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 6700 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 i5-12600K + AMD Radeon RX 6700 XT.
Can the Intel Core i5-12600K run the AMD Radeon RX 6700 XT?
Yes — the Intel Core i5-12600K runs the AMD Radeon RX 6700 XT comfortably. At 1440p the AMD Radeon RX 6700 XT is the limiting part (22% GPU-bound), which is the ideal balance: the Intel Core i5-12600K has headroom to spare, so you get the GPU's full performance.
Will the AMD Radeon RX 6700 XT bottleneck the Intel Core i5-12600K?
The Intel Core i5-12600K + AMD Radeon RX 6700 XT pairing is rated Grade B for 1440p gaming with a recommended 650W PSU. Resolution-by-resolution: 1080p: 19% GPU-bound, 1440p: 22% GPU-bound, 4K: 20% 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 i5-12600K + AMD Radeon RX 6700 XT build?
For a Intel Core i5-12600K (125W TDP) paired with a AMD Radeon RX 6700 XT (230W 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.
