The components you've chosen indicate that you're building a very high-performance gaming or work PC. Here's a quick rundown of the elements:
1-CPU: The Intel 13th Gen Core i9-13900KF is a powerful processor with 24 cores and a maximum turbo frequency of up to 5.8 GHz. It also features a generous cache memory of 68MB, which can significantly improve performance in multi-threaded tasks. As a 'KF' model, it doesn't have an integrated GPU but this should not be an issue with the dedicated GPU you've chosen.
2-Cooler: The Cooler Master MasterLiquid ML360L ARGB V2 is a liquid CPU cooler with a 360mm radiator. It should provide excellent cooling performance, which will be important for keeping the Core i9-13900KF cool during intensive tasks.
3-Motherboard: The ASUS Prime Z790-P is an ATX motherboard compatible with Intel's 12th and 13th Gen CPUs and supports Wi-Fi 6E and DDR5 memory. It's a good fit for your chosen processor and memory.
4-Storage: The Kingston KC3000 is a high-speed 1TB NVMe M.2 SSD. Its speed of up to 7,000MB/s will lead to fast boot times and quick loading of games or other software.
5-RAM: 16GB of Kingston FURY Beast RGB DDR5 memory will be more than sufficient for gaming and most other tasks. The 5600MHz speed is very fast, which could improve system performance.
6-GPU: The ASUS TUF Gaming GeForce RTX 4080 OC is a high-end graphics card with 16GB of GDDR6X memory. This card should be capable of running virtually any game at high settings.
7-PSU: The Seasonic FOCUS GX-850 is an 80+ Gold certified power supply, meaning it's very efficient. It provides 850W, which should be plenty to power your system. The full-modular design will also make cable management easier.
8-Case: The ASUS TUF Gaming GT501 is a mid-tower case that can accommodate EATX motherboards. It's designed with high airflow in mind, which will help keep your components cool.
Overall, this is an impressive build that will handle even the most demanding tasks smoothly. However, remember to double-check compatibility between all components before proceeding with the build.
