Built for rendering and AI learning

This desktop workstation pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5080 16GB GPU and 192GB of DDR5 memory. It targets creators and engineers who need sustained multi-threaded throughput for modelling, editing and AI learning workloads.

192GB DDR5 and 2TB NVMe headroom

The four-slot motherboard is fully populated at the 192GB maximum, removing any upgrade path for memory. The Samsung 990 PRO 2TB drive delivers up to 7450 MB/s reads and 6900 MB/s writes, leaving no internal 3.5-inch bay free unless the single 2.5-inch alternative is used.

Z890 platform with liquid cooling

A 360mm AIO cooler handles the CPU thermal load inside a Ceres 300 mid-tower case measuring 475 x 245 x 463 mm. The TUF Z890 motherboard adds Thunderbolt 4, USB 20Gbps and 10Gbps ports, Wi-Fi 7, Bluetooth5.4 and four M.2 slots, while a 1000W 80 PLUS Gold PSU powers the build.

Questions about this item

Will my older 3.5-inch hard drive fit in the Ceres 300 case alongside the 2TB Samsung 990 PRO?

The Ceres 300 mid-tower provides one bay that accepts either a single 3.5-inch drive or two 2.5-inch drives, so a legacy 3.5-inch HDD can be installed next to the existing M.2 SSD.

How can I verify the 360mm Quiet Edition liquid cooler is keeping the Core Ultra 9 285K within its thermal limits?

Monitor CPU package temperature in HWMonitor or the BIOS while under load; the 360mm AIO with three 140mm fans at 1500rpm is designed to handle the 24-core processor up to its 5.70GHz boost.

Which cables and accessories ship with the system besides the Windows 11 Pro licence?

The box includes the Ceres 300 tower with pre-installed 1000W 80 PLUS Gold PSU, 360mm AIO cooler, RTX 5080 16GB GPU, 192GB DDR5 RAM, 2TB Samsung 990 PRO SSD, motherboard I/O shield, front-panel USB 3.2 Gen 2 Type-C, two USB 3.0 and HD audio cables, plus a UK power cord.
