12-Core Liquid-Cooled Workstation Desktop

The Adamant Custom gaming PC ships new with a 12-core AMD Ryzen 9 9900X3D processor, 32 GB of DDR5 memory and a GeForce RTX 5090 graphics card. A 2 TB Samsung 990 PRO NVMe drive provides the primary storage. Windows 11 Pro is pre-installed for immediate workstation or gaming use.

PCI Express x16 Graphics and 192 GB Memory Ceiling

The RTX 5090 connects through a PCI Express x16 slot, defining the GPU bandwidth available to the system. Four DDR5 slots support a maximum of 192 GB, so the installed 32 GB can be expanded later. Two 3.5-inch and two 2.5-inch internal bays allow additional SATA drives if required.

32 GB RTX 5090 Frame Buffer

The graphics card carries 32 GB of video memory, the single specification that determines whether this system can hold the largest models and textures in VRAM. Buyers who need a larger frame buffer for 8K workloads or multi-GPU scaling cannot meet that need with this configuration.

Questions about this item

Should I pick the 32 GB DDR5 kit or add more sticks to reach the 192 GB maximum?

The board has four slots and ships with 32 GB DDR5; you can add three more modules later to hit the 192 GB ceiling without removing the original memory.

What does the Ryzen 9 9900X3D’s 5.50 GHz boost mean for daily workloads?

The 12-core CPU runs at 4.4 GHz base and can lift single threads to 5.50 GHz, so heavy compile jobs and gaming both see high clock speeds when thermal headroom allows.

How fast is the Samsung 990 PRO over its PCIe 4.0 x4 link?

The 2 TB drive tops out at 7450 MB/s read and 6900 MB/s write, which is the practical ceiling of the PCIe 4.0 x4 interface used by the M.2 slot.
