Engineered for professional modelling

The Adamant Custom tower pairs a 16-core AMD Ryzen 9 9950X3D with an NVIDIA RTX A4000 graphics card. Thirty-two gigabytes of DDR5 memory and a 1 TB NVMe drive handle large assemblies and simulation data. A 10 TB hard drive adds bulk storage for project archives. Liquid cooling keeps the CPU stable during extended compute runs. Windows 11 Pro is pre-installed.

Replaces an older workstation when

Single-thread speed and GPU memory become bottlenecks. The 16-core processor reaches 5.70 GHz boost with 128 MB L3 cache for responsive viewport interaction. Sixteen gigabytes of video memory on the RTX A4000 supports complex scenes without swapping. The jump is worth it when current hardware limits model size or iteration time. Four memory slots allow expansion up to 192 GB later.

Fits a desk with front-panel USB 3.2 Gen 2 Type-C

The mid-tower case measures 469 by 220 by 490 millimetres and includes dust filters on three sides. An 850 W 80 PLUS Bronze power supply delivers protected power to all components. The PRIME X870-P motherboard adds 2.5 Gb Ethernet and Wi-Fi 7 2x2 connectivity. Two internal 3.5-inch bays remain free for extra drives. Rear USB4 ports at 40 Gbps support fast peripherals.

Questions about this item

What clearance does the Antec P20 case need for the 360 mm liquid cooler radiator?

The 360 mm Quiet Edition AIO mounts in the top of the Antec P20 mid-tower; the case dimensions are 469 x 220 x 490 mm so allow at least that height plus cable routing space above the motherboard tray.

Which CPU power cables must be seated on the PRIME X870-P motherboard before the first boot?

Connect both the 24-pin ATX and the 8-pin EPS cables from the Thermaltake Smart 850 W PSU to the motherboard; the EPS connector sits near the AM5 socket and is often missed during first assembly.

How many additional DDR5 modules can be added later and what is the ceiling?

Four DDR5 slots exist in total and two are already populated with the 32 GB kit; you can add two more modules up to the motherboard limit of 192 GB.
