Workstation for CAD and AI

This Adamant Custom business desktop pairs an eight-core AMD Ryzen 7 9800X3D processor with an Nvidia RTX PRO 4000 Blackwell graphics card. One hundred twenty-eight gigabytes of DDR5 memory and a four-terabyte NVMe SSD support large assemblies and model training. The system ships with Windows 11 Pro and liquid cooling in a tempered-glass mid-tower case.

Upgrade from older workstation CPUs

The 9800X3D delivers up to 5.20 GHz boost clocks and ninety-six megabytes of L3 cache, reducing solve times in SolidWorks and accelerating AI inference workloads. The RTX PRO 4000 adds twenty-four gigabytes of video memory for GPU-accelerated rendering and simulation. Builders moving from platforms limited to sixty-four or ninety-six gigabytes of RAM will see the biggest jump.

Check motherboard memory limit and case clearance

The PRIME X870-P board supports a maximum of one hundred ninety-two gigabytes of DDR5, so this configuration leaves room for one more kit. Verify that the 240 mm liquid cooler fits your intended workspace and that the 850 watt power supply meets any local circuit limits. The chassis measures four hundred sixty-nine by two hundred twenty by four hundred ninety millimetres.

Questions about this item

What case clearance does the 240 mm liquid cooler need in the Antec P20 chassis?

The 240 mm AIO mounts to the top or front of the 469 x 220 x 490 mm case; verify the chosen radiator position clears the motherboard VRM heatsinks and the three 120 mm front fans.

Which motherboard power connectors must be seated for the Ryzen 7 9800X3D and RTX PRO 4000?

Connect the 24-pin ATX and 8-pin EPS cables to the PRIME X870-P board, then attach the required PCIe power leads from the 850 W supply to the graphics card before first boot.

How many M.2 slots remain free after the 4 TB Samsung 990 PRO is installed?

The X870-P provides four M.2 connectors; one is occupied by the factory NVMe drive, leaving three open for future PCIe 4.0 x4 SSDs.
