24-Core Intel Ultra 9 Workstation

This desktop pairs a 24-core Intel Core Ultra 9 285K processor with 128GB of DDR5 memory and an Nvidia RTX PRO 4000 Blackwell graphics card. It targets engineers and creators who run SolidWorks, CAD, CAM or CAE workloads that demand high core counts and professional GPU drivers. The system ships with Windows 11 Pro and a 1TB NVMe boot drive plus a 10TB hard drive for project storage.

360mm Liquid Cooler and 850W PSU

A 360mm quiet-edition AIO handles CPU thermals while three 120mm front fans move air through the tempered-glass mid-tower. The Thermaltake Smart 850W 80 PLUS Bronze unit uses a 140mm fan and Japanese main capacitors to deliver stable power with low acoustic output. Dust filters on the bottom, front and top help maintain airflow over time.

Z890 TUF Motherboard and Front I/O

The ATX board provides four M.2 slots, four SATA ports, Thunderbolt 4, USB 20Gbps and 10Gbps Type-C ports, plus 2.5Gb Ethernet and Wi-Fi 7. The case front panel adds two USB 3.0 ports, one USB 3.2 Gen 2 Type-C and audio jacks. Internal bays include two 3.5/2.5-inch and two dedicated 2.5-inch slots for future expansion.

Questions about this item

How do I mount the 360mm liquid cooler in the Antec P20 case without blocking the front panel USB 3.2 Gen 2 Type-C cable?

Install the radiator at the top of the case with tubes entering from the right side; the top dust filter removes without tools, giving clearance for the front-panel header cable that runs along the chassis roof.

When will the 850W 80 PLUS Bronze PSU and the 360mm AIO pump need replacement under daily workstation loads?

The PSU uses Japanese main capacitors rated for long life; expect ten-plus years. The AIO pump is a sealed unit — plan on swapping the whole cooler at the five-to-seven-year mark when flow noise rises.

Which component hits its thermal or power ceiling first during extended 24-core compile and render sessions?

The Ultra 9 285K reaches its 5.70 GHz boost limit and the 360mm AIO saturates before the RTX PRO 4000 24GB or the 128GB DDR5 hit their own thermal thresholds.
