Workstation for CAD and engineering

The Adamant Custom desktop pairs a 24-core Intel Core i9-14900K with an NVIDIA RTX A4000 GPU and 32GB DDR5 memory. It targets engineers and designers who need certified drivers for SolidWorks, CAM and CAE workloads. Windows 11 Pro is pre-installed and the system is described as AI Ready.

Installation notes and common issues

The 360 mm liquid cooler and 850W power supply are factory fitted inside an Antec P20 mid-tower case. Builders adding extra drives must use the two internal 3.5"/2.5" bays or the two dedicated 2.5" slots. The motherboard offers four DDR5 slots with 192 GB maximum capacity, so memory upgrades are straightforward. Front-panel USB 3.2 Gen 2 Type-C and rear 2.5Gb Ethernet are ready to use.

Capacity and headroom

The 2TB Samsung 990 PRO NVMe drive delivers up to 7450 MB/s read and 6900 MB/s write for active project files. A 10TB hard drive with 256 MB cache provides bulk storage for archives and datasets. The RTX A4000 handles complex 3D models and simulation datasets within its VRAM limit. Users running larger assemblies or multi-GPU render farms will exceed the single GPU and 32GB system memory configuration.

Questions about this item

How can I verify the 24-core i9-14900K and RTX A4000 are detected correctly in Windows 11 Pro after first boot?

Open Task Manager to confirm 24 cores and 32 threads on the CPU, check Device Manager for the NVIDIA RTX A4000 listing, and ensure the Samsung 990 PRO 2TB NVMe appears as the boot drive.

Which components come pre-installed in the Antec P20 case and what must I source separately?

The system ships fully assembled with the Z790 AORUS motherboard, liquid CPU cooler, 32GB DDR5 RAM, 2TB NVMe SSD, 10TB HDD, RTX A4000 GPU, 850W PSU, Wi-Fi 6 and BLUETOOTH 5.2; only a monitor, keyboard and mouse are needed separately.

Should I choose the 32GB DDR5 configuration or upgrade toward the 192GB maximum for large SolidWorks assemblies?

Start with the installed 32GB DDR5 across the four available slots; the board supports up to 192GB total, so add matched DDR5 modules later if assembly sizes demand more memory.
