Workstation desktop for modelling and AI

This Adamant Custom gaming desktop combines an 8-core AMD Ryzen 7 9800X3D processor with 128GB DDR5 memory and a 4TB NVMe solid-state drive. The system targets professionals who need sustained compute for video editing, rendering and AI learning workloads. Windows 11 Pro is pre-installed on the mid-tower chassis.

Liquid cooling sustains 5.20 GHz boost clocks

A 240 mm quiet-edition liquid cooler keeps the CPU at its peak frequency during long rendering sessions rather than throttling after a short burst. The Thermaltake 1200W 80 PLUS Gold power supply delivers stable current to the GeForce RTX 5090 32GB graphics card under continuous load. Rear-panel USB4 ports at 40Gbps maintain throughput for high-speed peripherals.

128GB DDR5 decides multi-task capacity

Four populated slots leave no room for further memory expansion without replacing modules, so buyers who need more than 128GB must choose a different configuration. The Samsung 990 PRO drive reaches 7450 MB/s read and 6900 MB/s write speeds for rapid asset loading. Intel 2.5Gb Ethernet and Wi-Fi 7 provide wired and wireless network connectivity.

Questions about this item

How loud is the 240 mm liquid cooler and 140 mm PSU fan when the Ryzen 7 9800X3D runs all day?

The 240 mm Quiet Edition AIO and the Thermaltake 1200 W unit's 140 mm fan are both designed for low noise, so sustained workloads stay quiet.

What display cable and monitor input do I need for the RTX 5090 32 GB?

The card uses a PCI Express x16 slot internally; you will need a monitor with DisplayPort or HDMI inputs and the matching cable, which are not included.

Will my existing SATA SSDs or hard drives fit inside the Antec P20 case?

Yes, the case provides two internal 3.5"/2.5" bays and two dedicated 2.5" bays, all served by the motherboard's four SATA 6 Gb/s ports.
