Liquid-cooled workstation desktop

This Adamant Custom gaming desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card. It runs Windows 11 Pro and includes a 240 mm liquid CPU cooler in a mid-tower case. The system is built for high-performance computing and gaming workloads.

Suits creators needing GPU memory and fast storage

The 32 GB GPU frame buffer and 4 TB NVMe SSD support large assets and rapid loading. Buyers who want more system memory than 32 GB DDR5 or who need additional M.2 slots populated should look at a different configuration. The four memory slots allow expansion up to 192 GB.

32 GB RTX 5090 frame buffer decides fit

The graphics card provides 32 GB of video memory, a capacity that determines whether the system handles your largest scenes and models. If your workflow demands more GPU memory, this card will not meet the requirement.
