Core Configuration

The Adamant Custom desktop is a liquid-cooled gaming PC built around a 12-core AMD Ryzen 9 9900X3D processor. It ships with 32GB of DDR5 memory and a 2TB NVMe SSD running Windows 11 Pro. Integrated Radeon graphics drive display outputs via HDMI and two USB4 ports.

Ideal User and Limits

This system suits creators and professionals who need strong multi-threaded CPU performance without a discrete graphics card. Buyers who want high-frame-rate 3D gaming or GPU-accelerated rendering should look at a configuration with a dedicated video card. The four memory slots allow expansion up to 192 GB for heavier workloads.

Deciding Specification

The defining component is the 12-core Ryzen 9 9900X3D CPU with 128 MB L3 cache and a 5.50 GHz maximum boost clock. This processor determines the system's capability for compilation, simulation and multi-tasking. If your workload depends on discrete GPU power, this integrated-graphics platform will not meet that need.

The CPU can boost to 5.50 GHz with 128 MB L3 cache, and the 240 mm liquid cooler is sized to keep temperatures within spec before any throttling occurs.

How loud and hot does the Thermaltake 850 W Bronze PSU get during all-day use?

The 850 W 80 PLUS Bronze unit uses a 140 mm ultra-quiet fan and Japanese main capacitors, delivering low noise and stable thermals under sustained loads.
