Liquid-cooled Ryzen 9 workstation

This business desktop pairs a 12-core AMD Ryzen 9 9900X processor with a 240 mm liquid cooler inside a Corsair 4000D tempered-glass chassis. It ships with 192 GB of DDR5 memory, a 2 TB Samsung 990 PRO NVMe drive and a 10 TB hard drive. Windows 11 Pro 64-bit is pre-installed and the system is described as AI Ready.

Suited for content creators needing quiet

The combination of high core-count CPU, professional Nvidia RTX A400 graphics with four Mini DisplayPort outputs and large mixed storage fits video editing, 3D rendering and CAD workflows. Buyers who require more than 4 GB of GPU memory or multiple full-size DisplayPort connectors should consider a different graphics configuration.

4 GB RTX A400 with four Mini DisplayPort outputs

The installed Nvidia RTX A400 provides 4 GB of video memory and drives up to four displays via Mini DisplayPort. This single specification determines whether the workstation can support the required monitor count and GPU memory budget for professional applications.

Questions about this item

Does the system ship with a monitor or do I need to buy one separately?

The desktop ships without a monitor, so a display must be purchased separately. The box contains the Corsair 4000D chassis with liquid-cooled Ryzen 9 9900X, 192GB DDR5, 2TB Samsung 990 PRO NVMe, 10TB HDD, RTX A400 4GB with four MiniDP outputs, 750W PSU, Windows 11 Pro and all cables.

Should I choose the 192GB DDR5 configuration or is a lower capacity available?

This unit is built with 192GB DDR5, the maximum supported by the X870 motherboard. If a smaller capacity is needed the configuration can be customised before ordering.

What does the 4.4GHz base clock mean for daily rendering workloads?

The 12-core Ryzen 9 9900X runs at 4.4GHz base and can boost to 5.20GHz with 96MB L3 cache, delivering strong multi-threaded throughput for content-creation tasks while the 240mm liquid cooler keeps temperatures controlled.
