12-Core Workstation Desktop

This Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card. It ships with 64GB of DDR5 memory, a 2TB NVMe SSD and a 10TB hard drive. The system targets professionals who need modelling, editing, rendering and AI learning performance in a single workstation.

AM5 Motherboard and 1200W PSU

The PRIME X870-P motherboard uses the AM5 socket and provides four memory slots with a 192GB maximum. A Thermaltake Toughpower 1200W 80 PLUS Gold unit supplies power through Japanese main capacitors. Verify that your workspace can accommodate the 490 x 239 x 486 mm Corsair 4000D case and its 240mm liquid cooler before ordering.

Sustained Load Cooling and Power

The 240mm quiet-edition liquid cooler and the PSU's 140mm ultra-quiet fan are designed to manage heat during extended rendering or training runs. Over-voltage, under-voltage, over-power and short-circuit protection help maintain stability when all 12 cores and the 32GB GPU operate continuously at up to 5.50 GHz.
