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

System identity

This liquid-cooled tower pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card and 32 GB of DDR5 memory. It ships with Windows 11 Pro on an 8 TB NVMe array built from two 4 TB Samsung 990 PRO drives. The platform targets professionals who need workstation-class compute and high-end graphics in a single chassis.

Sustained-load behaviour

A 240 mm quiet-edition AIO cooler handles the CPU while the Cooler Master HAF 500 case moves air through two 200 mm front fans, a rear 120 mm fan and a dedicated 120 mm GPU fan. The Thermaltake Toughpower 1200 W 80 PLUS Gold supply uses Japanese main capacitors and a 140 mm fan rated for ultra-quiet operation. Protection circuits cover over-voltage, under-voltage, over-power and short-circuit events.

Deciding specification

The 8 TB NVMe SSD delivers sequential reads up to 7 450 MB/s and writes up to 6 900 MB/s across four PCIe 4.0 lanes. Four total memory slots allow expansion to 192 GB of DDR5. Buyers who need more than 8 TB of high-speed storage or who require additional PCIe add-in cards beyond the GPU should verify slot and M.2 availability before ordering.
