Built for AI workloads and 4K rendering

This tower workstation pairs a 24-core Intel Core Ultra 9 285K processor with 64GB of DDR5 memory and an Nvidia GeForce RTX 5080 16GB graphics card. It ships with Windows 11 Pro and is configured for modelling, editing and AI learning tasks. The platform supports up to 192 GB of memory across four slots for future expansion.

Liquid-cooled chassis with high-speed I/O

A 360 mm quiet-edition AIO cooler handles the CPU inside a Corsair 4000D tempered-glass case. The Gigabyte Z890 UD motherboard provides rear USB4 Type-C, USB 3.2 Gen 2, four USB 3.2 Gen 1 and four USB 2.0 ports plus mid-board Type-C and Gen 1 headers. Storage combines a 1TB Samsung 990 PRO PCIe 4.0x4 NVMe drive with a 10TB HDD featuring 256MB cache. Connectivity includes Intel 2.5Gb Ethernet, Wi-Fi 6E AX211 and Bluetooth5.3.

1000W Gold PSU powers quiet thermal headroom

The Thermaltake Toughpower 1000W 80 PLUS Gold unit uses Japanese main capacitors and a 140 mm low-noise fan with over-voltage, under-voltage, over-power and short-circuit protection. Liquid CPU cooling and the case airflow keep temperatures controlled during sustained render or compute loads. Realtek 7.1 surround audio rounds out the platform.
