Adamant Custom Ryzen 9 9900X3D Workstation

This Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5080 graphics card. It ships with 128GB of DDR5 memory and a 4TB Samsung 990 PRO NVMe solid-state drive. Windows 11 Pro is pre-installed on the mid-tower chassis.

Suited to modelling, rendering and AI workloads

The liquid-cooled CPU and 1000W 80 PLUS Gold power supply support sustained multi-core performance for video editing and machine learning tasks. Buyers who need more than 128GB of memory should look elsewhere, as the board maxes out at 192GB. The single graphics card limits multi-GPU configurations.

128GB DDR5 memory capacity

Four DIMM slots are populated with high-performance DDR5 modules, leaving no free slots for easy expansion. The motherboard supports up to 192GB total, so adding capacity later requires replacing existing sticks. Verify your application's memory ceiling before ordering.

この商品に関する質問

What PCI Express lane width does the RTX 5080 graphics card use in this system?

The RTX 5080 connects through a PCI Express x16 slot on the PRIME X870-P motherboard, giving the GPU full 16-lane bandwidth for gaming and compute workloads.

What case dimensions and motherboard form factor determine whether this PC fits my desk space?

The Antec P20 mid-tower measures 469 mm deep, 220 mm wide and 490 mm high, and it accepts ATX boards such as the included X870-P.

How is the 240 mm liquid cooler mounted, and what step do builders often miss?

The 240 mm radiator is pre-fitted to the case with its two 120 mm fans; the step people forget is removing the protective film from the cold-plate before seating it on the Ryzen 9 9900X3D.
