Adamant Custom
A liquid-cooled desktop with a 12-core Ryzen 9 9900X3D, 192 GB DDR5, 2 TB NVMe storage and integrated Radeon graphics running Windows 11 Pro
This Adamant Custom gaming desktop is built around a twelve-core AMD Ryzen 9 9900X3D processor with a 4.3 GHz base clock and 128 MB of L3 cache. It ships with 192 GB of DDR5 memory filling all four slots and a 2 TB Samsung 990 PRO NVMe drive. Integrated Radeon graphics drive the display outputs while a 360 mm liquid cooler handles the CPU thermal load.
The integrated Radeon GPU provides HDMI and two USB4 ports for display connectivity, but it shares system memory and has no dedicated video memory. Demanding 3D workloads, high-refresh-rate gaming or multi-monitor setups at high resolution will be constrained by this architecture. Buyers who need discrete GPU performance should plan to add a graphics card.
The CPU is an AM5 socket part with twelve cores and twenty-four threads, capable of reaching 5.50 GHz boost. The motherboard is a TUF X870-PLUS with four M.2 connectors and rear USB4 at 40 Gbps. If your workload needs more than 192 GB of memory or requires a discrete graphics card, this configuration will not meet that need without changes.

The system ships with all four slots populated at 192GB DDR5, matching the motherboard maximum. This leaves no empty slots for future expansion but provides ample capacity for heavy multitasking and large datasets.
The Ryzen 9 9900X3D runs at 4.3GHz base with a 5.50GHz boost across 12 cores and 24 threads. The 360mm liquid cooler is designed to maintain high clocks during extended gaming or rendering sessions.
The rear panel includes two USB4 ports rated at 40Gbps each. They support display output via the integrated Radeon graphics and high-speed peripherals, but total throughput is shared with other USB traffic on the controller.
