Custom workstation for modelling and AI

This Adamant Custom tower pairs a 12-core Ryzen 9 9900X3D processor with an RTX 5090 graphics card and 128GB of DDR5 memory. The system targets professionals who need high single-thread frequency and large video memory for rendering, simulation or local AI inference workloads. Windows 11 Pro is pre-installed.

Build foundation with liquid cooling

A 240mm liquid cooler handles the CPU while a 1200W 80 PLUS Gold unit powers the entire platform. The PRIME X870-P motherboard provides four memory slots populated to 128GB with headroom to 192GB, four M.2 connectors and rear USB4 ports at 40Gbps. The Antec P20 case includes front USB 3.2 Gen 2 Type-C and dust filters on three sides.

Sustained throughput from fast SSD array

Two 4TB Samsung 990 PRO drives deliver sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec for active project files. A 10TB hard drive with 256MB cache stores bulk datasets and archives without slowing the primary array. Intel 2.5Gb Ethernet and Wi-Fi 7 keep network transfers steady during long compute sessions.
