Adamant Custom Ryzen 9 9900X3D 128GB DDR5 2TB NVMe gaming PC

Adamant Custom 12-Core Ryzen Workstation

This new Adamant Custom desktop ships with a 12-core AMD Ryzen 9 9900X3D processor running at 4.3 GHz with up to 5.50 GHz boost and 128 MB L3 cache. It includes 128 GB of DDR5 memory across four slots, a 2 TB Samsung 990 PRO NVMe SSD delivering up to 7450 MB/s read and 6900 MB/s write, and integrated AMD Radeon graphics with HDMI and dual USB4 outputs. Windows 11 Pro 64-bit is pre-installed.

360 mm Liquid Cooling and 850 W Bronze PSU

A 360 mm Quiet Edition AIO liquid cooler handles the CPU while two 140 mm PWM front fans move air through the tempered-glass case. The Thermaltake Smart 850 W 80 PLUS Bronze power supply uses Japanese main capacitors and a 140 mm fan rated for low noise, with over-voltage, under-voltage, over-power and short-circuit protection. Integrated 7.1-channel audio, Intel 2.5 Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4 complete the platform.

Sustained Load on Integrated Graphics

Under continuous workloads the 12-core CPU and integrated Radeon graphics share the same thermal envelope, so prolonged compute or media tasks will raise coolant temperature until the radiator and front fans reach equilibrium. The 850 W Bronze unit provides headroom for the CPU, memory, SSD and four M.2 slots, but the lack of a discrete GPU limits 3D rendering and gaming performance compared with systems that include one. Buyers needing dedicated graphics acceleration should consider a different configuration.
