Intel Core Ultra 9 285K system

This desktop is built around a 24-core Intel Core Ultra 9 285K processor running at 5.7GHz on the LGA 1851 socket. It targets enthusiasts who want a high-end gaming machine that arrives fully assembled, liquid cooled and ready for Windows 11 Home. The configuration suits 4K play and heavy multitasking without component selection hassle.

240mm liquid cooler and 1000W supply

A 240mm all-in-one cooler handles the CPU thermal load while a 1000W power unit feeds the GeForce RTX 5080 and remaining components. The cooling loop and PSU headroom are chosen to sustain boost clocks during extended sessions. WiFi and RGB lighting are integrated into the Gigabyte C301 GLASS chassis.

64GB DDR5 and 4TB NVMe

Sixty-four gigabytes of DDR5 memory across four slots provides ample space for large textures, virtual machines and background apps. The 4TB NVMe SSD holds a sizeable game library and project files with fast load times. Buyers who want more storage or a second graphics card will need to add drives or upgrade the platform themselves.

Questions about this item

How often should the 240mm liquid cooler be serviced or the coolant replaced on the Core Ultra 9 285K?

The sealed 240mm liquid cooler is maintenance-free for the life of the system; no coolant changes or pump servicing are required.

Which component hits its thermal or power ceiling first during extended gaming on the RTX 5080 16GB GDDR7?

The RTX 5080 16GB GDDR7 typically reaches its thermal limit before the 1000W power supply or the Core Ultra 9 285K under sustained loads.

What are the noise and heat levels when the 1000W PSU and liquid cooler run all day?

The 240mm liquid cooler keeps CPU temperatures low with quiet pump operation, while the 1000W PSU fan spins slowly, producing minimal noise and heat during continuous use.
