12-Core Ryzen 9 9900X3D Workstation

The Adamant Custom tower combines a 12-core AMD Ryzen 9 9900X3D processor at 4.4 GHz with 192 GB DDR5 memory and an Nvidia GeForce RTX 5070 Ti 16 GB graphics card. A 240 mm liquid cooler keeps the CPU stable under sustained modelling, rendering or AI workloads. Windows 11 Pro 64-bit is pre-installed.

192 GB DDR5 and 8 TB NVMe Storage

This system suits professionals who need large memory capacity and fast storage for video editing, 3D rendering or machine-learning datasets. The 8 TB NVMe array uses two 4 TB Samsung 990 PRO drives reaching 7450 MB/s read and 6900 MB/s write. Builders who require more than 192 GB RAM or additional drive bays should consider a different platform.

PRIME X870-P Motherboard Connectivity

The PRIME X870-P board provides rear USB4 ports at 40 Gbps, 10 Gbps and 5 Gbps USB, plus 2.5 Gb Ethernet and Wi-Fi 7 wireless. Four M.2 slots and two SATA 6 Gbps ports allow further storage expansion. The 850 W 80 PLUS Bronze PSU powers the complete build.

Questions about this item

What PCI Express generation does the RTX 5070 Ti use, and what bandwidth ceiling does that set?

The graphics card connects via a PCI Express x16 slot on the PRIME X870-P motherboard; the board's M.2 sockets are wired for PCIe 4.0 x4, giving a practical reference for the platform's high-speed lane budget.

What are the case dimensions and motherboard form factor needed to fit this build?

The Antec P20 mid-tower measures 469 mm deep, 220 mm wide and 490 mm high and accepts E-ATX boards, so the PRIME X870-P ATX motherboard and 240 mm AIO cooler fit with standard clearance.

How is the 192 GB DDR5 memory installed on the PRIME X870-P, and which step is often missed?

The board has four DIMM slots; the 192 GB kit fills all four, so each module must be seated until the retention clips click on both ends — partial seating on the outer clips is the common oversight.
