Core specification

This Adamant Custom tower is a liquid-cooled Windows 11 Pro workstation built around a 16-core AMD Ryzen 9 9950X3D processor running at 4.3 GHz with a 5.70 GHz boost. It pairs 128GB of DDR5 memory with two 4TB Samsung 990 PRO NVMe drives and a 10TB hard drive with 256MB cache. An NVIDIA RTX A4000 graphics card with 16GB of memory handles professional visualisation tasks. The system sits in an Antec P20 mid-tower case powered by an 850W 80 PLUS Bronze supply.

Suited for

Engineers and designers running SolidWorks, CAD, CAM or CAE workloads that benefit from high core counts, large memory capacity and certified professional graphics will find this configuration ready to use. Buyers who need more than 128GB of RAM should note the motherboard supports up to 192GB across four slots. Users whose applications rely on consumer-grade GeForce features or who require a different GPU form factor should look at alternative configurations.

Deciding factor

The installed NVIDIA RTX A4000 16GB is a professional visualisation card with certified drivers for engineering ISV applications. If your workflow depends on those certifications, this GPU is the correct choice. If you need gaming-oriented features, higher compute density or a different memory configuration, this specific card will not match those requirements.

Questions about this item

Will the Prime X870-P motherboard and 850 W power supply fit into my existing ATX case?

The Antec P20 case supplied with this system is a mid-tower measuring 469 x 220 x 490 mm and accepts E-ATX motherboards. The Thermaltake Smart 850 W PSU uses a standard ATX footprint, so it will mount in any case designed for ATX power supplies.

How can I verify that the Ryzen 9 9950X3D is running at its 5.70 GHz boost and the RTX A4000 is recognised with 16 GB VRAM?

Open Windows Task Manager or HWInfo after boot. The CPU should show 16 cores and 32 threads with a maximum frequency of 5.70 GHz. The GPU entry will list Nvidia RTX A4000 and 16 GB dedicated memory.

Does the box include Wi-Fi antennas, a Windows licence and the 360 mm liquid cooler pre-installed?

The system ships fully assembled inside the Antec P20 chassis. The 360 mm Quiet Edition AIO cooler is already mounted on the CPU. Wi-Fi 7 antennas are included for the Intel 2.5 Gb Ethernet and Wi-Fi 7 2x2 card. Windows 11 Pro is pre-installed and activated.
