Core Ultra 9 285K Gaming Workstation

This liquid-cooled desktop pairs a 24-core Intel Core Ultra 9 285K processor with 128GB of DDR5 memory and an Nvidia GeForce RTX 5070 graphics card. It targets creators and gamers who need high multi-threaded performance and modern AI-ready hardware in a pre-built Windows 11 Pro system.

Samsung 990 PRO SSD plus 10TB hard drive

The boot drive is a 2TB PCIe 4.0 NVMe unit rated for 7450 MB/s reads and 6900 MB/s writes, while a 10TB mechanical drive with 256MB cache adds bulk storage. Together they remove the usual compromise between application speed and archive capacity.

850W Bronze power supply constraint

The Thermaltake Smart 850W 80 PLUS Bronze unit sets the ceiling for future GPU upgrades; builders planning a higher-wattage card will need to replace the PSU. The motherboard offers four memory slots with a 192GB maximum for later expansion.

Questions about this item

Will the 360 mm liquid cooler need coolant replacement or pump service?

The 360 mm Quiet Edition AIO is a sealed unit designed for the Intel Core Ultra 9 285K; no coolant replacement or pump service is required during normal use.

What thermal limit appears first when the 24-core CPU runs at 5.70 GHz for long sessions?

The liquid cooler and case fans rated at 30 dBA set the practical thermal ceiling before the processor hits its maximum junction temperature.

How loud is the system when the 850 W Bronze PSU and 140 mm fans run continuously?

Front and rear 140 mm fans operate at 1500 rpm producing 30 dBA each, while the PSU uses an ultra-quiet 140 mm fan for low overall noise.
