Purpose-Built Workstation

This Adamant Custom tower pairs a 16-core AMD Ryzen 9 9950X3D with an NVIDIA RTX A4000 16GB professional GPU. The system ships with 64GB DDR5 memory, a 1TB NVMe SSD and a 10TB HDD. Windows 11 Pro is pre-installed on the 1TB drive. Liquid cooling keeps the CPU stable under sustained engineering loads.

Professional Fit

Engineers running SolidWorks, CAD, CAM or CAE workflows benefit from the certified driver stack and 16GB of GPU memory. The 16-core CPU handles simulation and multi-threaded rendering efficiently. Buyers who need more than 64GB of system memory or a second professional graphics card should consider a different chassis. The single RTX A4000 limits multi-GPU compute scaling.

GPU Memory Decides

The RTX A4000 provides 16GB of VRAM, which determines the maximum model size that fits in GPU memory for viewport and render tasks. Assemblies and datasets larger than this capacity will spill to system RAM and lose performance. The 64GB DDR5 pool and 192GB maximum offer headroom for CPU-side data, but the 16GB GPU limit remains the hard boundary for hardware-accelerated workflows.

Questions about this item

How is the 360 mm liquid cooler installed, and what step do people get wrong?

The cooler mounts on the CPU socket using the supplied AM5 bracket; the step often missed is removing the protective film from the cold-plate before securing the pump block.

What maintenance or replacement will the 360 mm AIO and the 850 W PSU need later?

The sealed AIO requires no coolant refill; plan to clean the radiator fins and replace the three 120 mm front fans and the PSU 140 mm fan when noise or airflow drops.

What limit shows up first under sustained load on the Ryzen 9 9950X3D with this 360 mm cooler?

The CPU will hit its thermal ceiling and throttle before the 850 W PSU reaches its 80 PLUS Bronze rating limit.
