Ultra 9 285K workstation

This desktop pairs a 24-core Intel Core Ultra 9 285K processor with 128GB of DDR5 memory and an Nvidia GeForce RTX 5060 graphics card. It ships with Windows 11 Pro installed and is aimed at creators and engineers who need strong multi-threaded compute alongside GPU acceleration. Liquid cooling keeps the CPU stable under sustained workloads.

Tower chassis with liquid cooling

A 360mm quiet-edition AIO cooler handles the processor while 140mm case fans move air through the Ceres 300 tempered-glass mid-tower. The Thermaltake Smart 850W 80 PLUS Bronze power supply uses a Japanese main capacitor and protections for over-voltage, under-voltage, over-power and short-circuit. Front I/O includes USB 3.2 Gen 2 Type-C, two USB 3.0 ports and HD audio.

8TB NVMe plus 10TB HDD storage

Two 4TB Samsung 990 PRO PCIe 4.0x4 drives deliver up to 7450 MB/s reads and 6900 MB/s writes for active projects. A 10TB hard drive with 256MB cache adds deep capacity for archives and media libraries. Four M.2 slots and four SATA 6Gb/s ports on the TUF Gaming Z890-PLUS WiFi7 motherboard leave room for future expansion.

Questions about this item

What does the Thunderbolt 4 Type-C port on the rear I/O cap at in practice?

The rear Thunderbolt 4 Type-C port supports up to 40 Gbps data, DisplayPort video and power delivery for compatible peripherals.

What clearance and mounting points does the 360 mm liquid cooler require inside the Ceres 300 case?

The 360 mm radiator mounts to the front of the Ceres 300 mid-tower using three 140 mm fan positions; the case provides 475 mm depth and 463 mm height for clearance.

How is the 128 GB DDR5 memory installed across the Z890 motherboard, and which slot order avoids the common boot failure?

The board has four DDR5 slots; populate the two primary slots first (usually A2 and B2) with the matched 128 GB kit so the memory controller trains correctly on first boot.
