Workstation CPU and AI readiness

This desktop uses a 24-core Intel Core Ultra 9 285K processor on an LGA 1851 socket with a Z890 chipset. The system ships with 64 GB of DDR5 memory across four slots and supports up to 192 GB total. It targets SolidWorks CAD, CAM and CAE modelling workloads as well as AI-ready compute tasks. Windows 11 Pro is pre-installed.

Compatibility checks before ordering

Verify that your peripherals and monitors suit the rear I/O: one Thunderbolt 4 Type-C port, one USB 20 Gbps Type-C, three USB 10 Gbps and three USB 5 Gbps ports. Internal expansion uses four SATA 6 Gbps connectors and four M.2 slots, two of which are occupied by the supplied SSDs. Network infrastructure should support 2.5 Gbps Ethernet and Wi-Fi 7 with Bluetooth 5.4. The 850 W power supply uses an ATX form factor.

Build quality and daily implications

The Antec P20 mid-tower case measures 469 by 220 by 490 mm and includes tempered glass panels with dust filters on bottom, front and top. Front-panel I/O provides two USB 3.0 ports, one USB 3.2 Gen 2 Type-C and audio jacks. A 360 mm liquid cooler handles the CPU while a 140 mm fan cools the PSU. Storage comprises two 4 TB Samsung 990 PRO PCIe 4.0 drives and a 10 TB hard drive with 256 MB cache. The RTX PRO 4000 Blackwell GPU adds 24 GB of video memory. Realtek 7.1 surround sound completes the platform.

Questions about this item

What is included in the box and what must I buy separately?

The system ships with the Antec P20 tower, liquid-cooled 24-core Intel Core Ultra 9 285K, 64GB DDR5, two 4TB Samsung 990 PRO NVMe drives, 10TB HDD, Nvidia RTX PRO 4000 Blackwell 24GB GPU, Thermaltake 850W PSU, Windows 11 Pro, Wi-Fi 7 and Bluetooth 5.4. Only a monitor, keyboard and mouse are needed.

Should I choose a different memory or storage configuration?

The board has four DDR5 slots supporting up to 192GB, so 64GB leaves room for expansion. Two 4TB NVMe drives occupy two of four M.2 slots; two slots and two 3.5-inch bays remain free for extra NVMe or SATA storage.

What does the 5.70 GHz figure mean in daily work?

That is the maximum single-core turbo frequency of the Core Ultra 9 285K. In CAD, rendering or simulation workloads the processor will hit this speed on lightly threaded bursts, while sustained all-core speeds run lower under the 360 mm liquid cooler.
