Professional Workstation Platform

This Adamant Custom tower pairs a 16-core AMD Ryzen 9 9950X3D processor with 128GB of DDR5 memory and an Nvidia RTX A4000 16GB graphics card. The system runs Windows 11 Pro on a 1TB NVMe SSD with a 10TB hard drive for bulk storage, all cooled by a 360mm liquid cooler in a Corsair 4000D chassis.

Engineers and Content Creators

The configuration suits professionals running SolidWorks, CAD, CAM or CAE workloads that benefit from high single-thread frequency and 16GB of GPU VRAM. Buyers who need more than 128GB of system memory or require multiple professional GPUs should look at a different platform.

192GB Maximum Memory Support

The TUF X870-PLUS motherboard supports up to 192GB of DDR5 across four slots, so the installed 128GB kit leaves room for future expansion if your datasets grow beyond the current capacity.

Questions about this item

What case dimensions and radiator size should I allow for when fitting this system?

The Corsair 4000D case measures 490 mm deep, 239 mm wide and 486 mm high and the 360 mm AIO radiator mounts in the top or front panel.

What is the main installation step people get wrong when adding storage to this X870 motherboard?

The board has four M.2 slots; the primary slot shares bandwidth with the top PCIe x16 slot, so install the OS drive in the CPU-attached M.2_1 slot and keep the GPU in the top slot.

Which components in this build will need periodic replacement or servicing?

The 360 mm AIO liquid cooler should have its coolant checked every two to three years, the 850 W PSU fan may need cleaning, and the 10 TB HDD is the only mechanical part likely to wear out first.
