12-Core Workstation Desktop

The Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card. It ships with 64 GB of DDR5 memory and a 2 TB NVMe solid-state drive. Windows 11 Pro comes pre-installed on a liquid-cooled chassis designed for sustained workloads.

Suits modelling and AI tasks; not for compact builds

This system targets professionals running modelling, video editing, rendering or AI learning workloads that benefit from 12 cores and 32 GB of GPU memory. Buyers who need a smaller footprint or quieter air cooling should consider alternative form factors. The four memory slots support expansion up to 192 GB for future growth.

ATX motherboard with extensive rear I/O

The TUF X870-PLUS motherboard provides USB4, 10 Gbps and 5 Gbps USB ports plus 2.5 Gb Ethernet and Wi-Fi 7 connectivity. Four M.2 connectors and two SATA ports allow additional storage without using the front 3.5-inch or 2.5-inch bays. A 1200 W 80 Plus Gold power supply delivers headroom for the GPU and CPU under full load.

Questions about this item

Does the AM5 socket on the Ryzen 9 9900X3D need a specific DDR5 kit to run at 64GB?

The motherboard ships with 64GB of DDR5 installed across four slots and supports up to 192GB, so no extra kit is required for the listed capacity.

Can I keep my SATA 6Gb/s drives when moving to the X870 motherboard?

Yes, the board provides two SATA 6Gb/s ports alongside four M.2 connectors, so existing SATA SSDs or HDDs will connect directly.

How do I confirm the RTX 5090 is running at PCI Express x16 after assembly?

Check the GPU-Z or BIOS PCIe link width field; it should read x16 when the card is seated in the primary slot.
