System purpose

This gaming desktop is built around an Intel Core Ultra 9 285K processor and an NVIDIA GeForce RTX 5070 graphics card. It targets enthusiasts who want a pre-assembled Windows 11 machine for high-refresh gaming and heavy multitasking. The 24-core CPU runs at a 5.7GHz base frequency on the LGA 1851 platform.

Thermals and power

A 240mm liquid cooler handles the CPU heat load while the 850W power supply feeds the GPU and other components. The ASUS TUF GT301 chassis provides airflow for the graphics card and storage drives. Under typical gaming loads the system runs within expected thermal and acoustic limits for a liquid-cooled build.

Deciding specification

The 128GB DDR5 memory kit fills all four slots, so no further RAM upgrades are possible without replacing modules. Buyers who anticipate needing more than 128GB should consider a different configuration. The 12GB GDDR7 frame buffer on the RTX 5070 defines the upper texture and resolution ceiling for modern titles.

Questions about this item

How do I install the 240mm liquid cooler in the ASUS TUF GT301 case?

The cooler ships pre-filled and mounted on the CPU. Connect the pump header and fan cables to the motherboard, then secure the radiator to the case using the supplied brackets and screws.

What maintenance will the 240mm liquid cooler need later?

The sealed loop requires no refilling. Clean dust from the radiator fins and fans every few months to maintain airflow.

What limit appears first during sustained loads on the Core Ultra 9 285K?

The 240mm radiator's heat capacity caps CPU boost clocks before the 850W power supply or GPU thermal limits are reached.
