Business desktop with 12-core Ryzen 9 9900X

This system ships as a new business desktop built around a 12-core AMD Ryzen 9 9900X processor. It includes 64GB of DDR5 memory, a 2TB NVMe SSD and a 10TB hard drive. A liquid-cooled Nvidia RTX A400 graphics card with four Mini DisplayPort outputs drives professional visual workloads. Windows 11 Pro 64-bit is pre-installed.

Professionals needing multi-display workstation

The four Mini DisplayPort connectors support up to four monitors for financial modelling, CAD or multi-stream video editing. AI-ready hardware accelerates supported creative and analytical applications. Buyers who need more than 4GB of GPU memory for large 3D scenes or GPU compute clusters should evaluate a different graphics configuration.

64GB DDR5 memory installed

The platform provides 64GB of DDR5 RAM and the motherboard supports up to 192GB total. This capacity suits most professional multitasking and virtualisation scenarios today. If the workflow demands the maximum 192GB from day one, additional modules will be required.

Questions about this item

Will the 240 mm liquid cooler keep the Ryzen 9 9900X at its 4.4 GHz base clock during long renders?

The 240 mm Quiet Edition AIO is designed for the 12-core Ryzen 9 9900X and its 4.4 GHz base frequency, with a 140 mm low-noise fan on the radiator.

How loud is the system when the RTX A400 and CPU run flat-out all day?

The 140 mm radiator fan and the Thermaltake Smart 750 W PSU both use ultra-quiet 140 mm fans rated for low noise under load.

Do I need to buy any cables or adapters to use the four Mini DisplayPort outputs on the RTX A400?

The card provides four native Mini DisplayPort connectors; you only need Mini DisplayPort-to-DisplayPort or Mini DisplayPort-to-HDMI cables for your monitors.
