Core Configuration

This desktop arrives as a complete gaming workstation built around a 24-core Intel Core Ultra 9 285K processor and 32GB of DDR5 memory. The system targets creators and enthusiasts who want high single-thread speed and multi-thread throughput without assembling components themselves. Windows 11 Pro is pre-installed and the build carries a three-year warranty.

Build Integration

The tower chassis measures 447 by 215 by 469 millimetres and includes a 360mm liquid cooler for the CPU, so the only external requirements are a display, keyboard and mouse. Four memory slots are present with 192GB maximum support, two 3.5-inch and two 2.5-inch drive bays remain open, and four M.2 connectors are available on the motherboard. A 1200W 80 PLUS Gold power supply delivers headroom for the installed GeForce RTX 5090 32GB graphics card.

Included Extras

The motherboard provides rear USB4 Type-C, multiple USB 3.2 and USB 2.0 ports, Intel 2.5Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4 connectivity. Front-panel I/O adds a USB 3.2 Gen 2x2 Type-C port, two USB 3.0 ports and audio jacks. The Samsung 990 PRO 1TB NVMe SSD offers sequential reads up to 7450 MB/s and writes up to 6900 MB/s. Realtek 7.1 surround audio completes the feature set.

Questions about this item

How long can the 360 mm AIO keep the 24-core CPU at 5.70 GHz before it throttles?

The 360 mm Quiet Edition liquid cooler is built for sustained loads on the 24-core Intel Core Ultra 9 285K, but exact throttle time depends on ambient temperature and case airflow.

What noise level does the 1200 W PSU fan reach under full GPU and CPU load?

The Thermaltake Toughpower 1200 W 80 PLUS Gold unit uses an ultra-quiet 140 mm fan designed for low noise even at high output.

Does the motherboard include the Wi-Fi 7 antennas, or must I buy them separately?

The GIGABYTE Z890 EAGLE WIFI7 board ships with the external antenna kit required for 802.11be operation.
