THE SHORT ANSWER
The Intel Core Ultra 5 245K + NVIDIA GeForce GTX 1660 Ti pairing is rated Grade C for 1440p gaming with a recommended 450W PSU. Resolution-by-resolution: 1080p: 35% GPU-bound, 1440p: 35% GPU-bound, 4K: 35% 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 Ultra 5 245K + NVIDIA GeForce GTX 1660 Ti pair is 35% GPU-limited at 1440p. Same pattern at 1080p and 4K. As a build, it grades capable (C).
Expect around 218 FPS in League of Legends and ~39 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 7700 XT is an option to consider — check the compatibility notes and historical pricing below before buying. Plan on at least a 450W PSU — that includes headroom for transient spikes on the NVIDIA GeForce GTX 1660 Ti.
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 Ultra 5 245K + NVIDIA GeForce GTX 1660 Ti.
Can the Intel Core Ultra 5 245K run the NVIDIA GeForce GTX 1660 Ti?
Yes — the Intel Core Ultra 5 245K runs the NVIDIA GeForce GTX 1660 Ti comfortably. At 1440p the NVIDIA GeForce GTX 1660 Ti is the limiting part (35% GPU-bound), which is the ideal balance: the Intel Core Ultra 5 245K has headroom to spare, so you get the GPU's full performance.
Will the NVIDIA GeForce GTX 1660 Ti bottleneck the Intel Core Ultra 5 245K?
The Intel Core Ultra 5 245K + NVIDIA GeForce GTX 1660 Ti pairing is rated Grade C for 1440p gaming with a recommended 450W PSU. Resolution-by-resolution: 1080p: 35% GPU-bound, 1440p: 35% GPU-bound, 4K: 35% 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 Ultra 5 245K + NVIDIA GeForce GTX 1660 Ti build?
For a Intel Core Ultra 5 245K (125W TDP) paired with a NVIDIA GeForce GTX 1660 Ti (120W TDP), we recommend a 450W power supply at minimum. This includes 40% headroom over the parts' combined TDP plus 100W for the motherboard, RAM, fans, and storage.
