Workstation-class desktop

This tower system pairs a 16-core AMD Ryzen 9 9950X3D processor with 128GB of DDR5 memory and an Nvidia RTX A2000 graphics card. It ships with Windows 11 Pro and a 360mm liquid cooler. The 8TB of NVMe solid-state storage is complemented by a 10TB hard drive.

Engineers and modellers

The CPU delivers 32 threads at up to 5.70 GHz with 128MB of L3 cache, while the GPU provides 12GB of video memory for CAD, CAM and CAE workloads. Buyers who need more than 128GB of RAM or a graphics card certified for a different ISV suite should look elsewhere.

128GB DDR5 baseline

Four memory slots are populated to reach 128GB, with the motherboard supporting a maximum of 192GB. This capacity determines whether the system can hold the large assemblies and simulation data typical of professional engineering workflows.

Questions about this item

How can I verify the liquid cooler is running after I power on the system?

The 360 mm AIO quiet edition water cooler spins up immediately; listen for pump noise and check CPU temperatures in BIOS or Windows 11 Pro — idle temps should sit well below the 4.3 GHz base clock thermal envelope.

Which drives and cables are included and what must I add for extra storage?

Two 4 TB Samsung 990 PRO M.2 SSDs and one 10 TB 3.5" HDD with 256 MB cache are installed; the case has two free 3.5" bays, two free 2.5" bays and four SATA 6 Gb/s ports on the GIGABYTE X870 AORUS board for additional SATA drives.

Should I choose the 128 GB DDR5 configuration or upgrade to the 192 GB maximum?

128 GB DDR5 fills all four slots with high-performance modules and suits most SolidWorks, CAD, CAM and CAE workloads; move to 192 GB only if you routinely exceed 128 GB in large assemblies or simulation datasets.
