Adamant Custom 12-Core Liquid Cooled Gaming PC Ryzen 9 9900X3D 32GB DDR5 8TB NVMe 10TB HDD RTX 5090

12-Core Ryzen 9 Workstation

This desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 32 GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. It targets professionals who need strong multi-threaded compute and high-end GPU acceleration in a single tower. The system ships with Windows 11 Pro installed and is described as AI Ready for local inference workloads.

PCIe 4.0 Storage and I/O Limits

Two 4 TB Samsung 990 PRO drives deliver up to 7450 MB/s read and 6900 MB/s write speeds over a PCIe 4.0 x4 interface. The motherboard provides four M.2 slots in total, so two remain open for future expansion. Rear I/O includes two USB4 ports at 40 Gbps, one USB 10 Gbps port, three USB 5 Gbps ports and four USB 2.0 ports for peripheral connectivity.

Liquid-Cooled Tower with 1200 W Gold PSU

A 240 mm quiet-edition AIO cooler handles the CPU while the Antec P20 mid-tower case supplies three 120 mm front fans and dust filters on bottom, front and top panels. The Thermaltake Toughpower 1200 W 80 PLUS Gold unit uses Japanese main capacitors and a 140 mm fan with over-voltage, under-voltage, over-power and short-circuit protection. Front panel access offers two USB 3.0 ports, one USB 3.2 Gen 2 Type-C port and audio jacks.
