Built for creators and engineers

The Adamant Custom workstation pairs a 12-core Ryzen 9 9900X3D processor with an RTX 5090 graphics card holding 32GB of video memory. Windows 11 Pro drives the system, supported by 32GB of DDR5 RAM and a 1TB NVMe boot drive. A 10TB mechanical drive adds deep bulk storage for large project archives.

Liquid-cooled chassis with modern I/O

A 240mm liquid cooler handles the CPU while the Corsair 4000D case supplies front-panel USB 3.2 Type-C and audio. The PRIME X870-P motherboard contributes rear USB4 ports at 40Gbps, Intel 2.5Gb Ethernet and Wi-Fi 7 wireless. Four M.2 slots and internal 3.5-inch bays allow future storage expansion without external enclosures.

Replaces older workstations lacking PCIe 4.0 NVMe

The Samsung 990 PRO delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s, cutting load times for massive datasets. Builders who need more than 32GB of system memory can populate the four DDR5 slots up to 192GB. Buyers who want more storage bays than the two 3.5-inch slots provide should plan external arrays.

Questions about this item

What PCI Express generation does the graphics interface use and what bandwidth does it cap at?

The RTX 5090 connects via PCI Express x16 on the X870 motherboard, delivering up to 40 Gbps through the rear USB4 ports.

What case dimensions and drive bays must the build accommodate?

The Corsair 4000D case measures 490 x 239 x 486 mm and provides two 3.5-inch and two 2.5-inch internal bays for the 10 TB HDD and 1 TB SSD.

How is the CPU cooler installed and which step is often missed?

The 240 mm AIO mounts to the AM5 socket with the supplied bracket; the step people forget is tightening the pump block in a cross pattern to ensure even contact.
