Workstation-grade gaming desktop

The Adamant Custom system pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card. It ships with 192GB of DDR5 memory and a 4TB Samsung 990 PRO NVMe drive. Windows 11 Pro is pre-installed on a mid-tower chassis cooled by a 240mm liquid loop.

Suits AI and content workflows

Builders who need 192GB of unified memory for large-language-model inference, 3D rendering or multi-camera video editing will use every slot. The four DIMM sockets are fully populated, so there is no room for further memory expansion. Buyers who only game at 1080p or who want an upgrade path beyond 192GB should consider a different configuration.

Build integration notes

The Cooler Master HAF 500 case provides front-panel USB 3.2 Gen 2 Type-C and Gen 1 ports alongside a 2.5Gb Ethernet jack and Wi-Fi 7 connectivity. The motherboard adds two USB4 ports and four M.2 sockets, one of which is occupied by the boot drive. A 1200W 80 PLUS Gold power supply delivers headroom for the 32GB GPU and liquid cooler.

Questions about this item

Does the motherboard include a USB 20Gbps header so I can add a front-panel Type-C port?

The TUF X870-PLUS board provides one USB 20Gbps connector on the mid-board for that purpose.

Will my existing PCI Express x16 graphics card fit in the second slot if I keep the RTX 5090 as primary?

The motherboard has a single PCI Express x16 slot wired for the RTX 5090; there is no second full-length slot for another discrete GPU.

How can I confirm the Samsung 990 PRO is running at PCIe 4.0 x4 after setup?

Check the drive properties in Windows or the BIOS; the NVMe SSD should report a link width of x4 and a speed of 4.0 GT/s per lane.
