Workstation power

This Adamant Custom desktop pairs a 16-core AMD Ryzen 9 9950X with 192GB of DDR5 memory and an Nvidia RTX A4000 graphics card. The tower chassis uses liquid cooling and runs Windows 11 Pro out of the box. It is built for engineers and creators who need sustained multi-threaded compute and professional GPU drivers.

Suited to simulation not casual play

The configuration targets CAD, CAE and SolidWorks workloads that benefit from 16 cores, 32 threads and 16GB of VRAM. Buyers who only need gaming performance or lighter office tasks will find the specification excessive. Those who require ECC memory or certified ISV drivers beyond the RTX A4000 should look at dedicated workstation lines.

Storage headroom and limits

Dual 4TB Samsung 990 PRO NVMe drives deliver up to 7450 MB/s reads and 6900 MB/s writes for active projects, while a 10TB HDD adds bulk capacity. The motherboard provides four M.2 slots in total, so two remain open for future expansion. Memory is capped at 192GB across four slots, so larger datasets must move to the NVMe array or external storage.

Questions about this item

Does the 192GB DDR5 memory fill every slot on the PRIME X870-P motherboard?

Yes, the board provides four DDR5 slots and the 192GB kit occupies all of them, leaving no free slots for further expansion.

Can the RTX A4000 16GB GPU share the same 850W PSU with the liquid-cooled Ryzen 9 9950X without exceeding the unit's rated output?

The 850W 80 PLUS Bronze supply is sized for the full build; both the 16-core CPU and the 16GB professional GPU draw well within its continuous capacity.

After first boot, how can I confirm the two 4TB Samsung 990 PRO drives are running at PCIe 4.0 x4 speeds?

Open Task Manager or a benchmark tool and verify each drive reports sequential reads near 7450 MB/sec and writes near 6900 MB/sec.
