System summary

The Adamant Custom desktop is a liquid cooled gaming PC built around a twelve core AMD Ryzen 9 9900X3D processor. It ships with 128GB of DDR5 memory, a 2TB NVMe solid state drive and a 10TB mechanical hard drive. Windows 11 Pro is preinstalled and the integrated Radeon graphics drive HDMI and dual USB4 outputs. This configuration targets creators and enthusiasts who want high core counts and large local storage in a single chassis.

Sustained load behaviour

A 240mm quiet edition liquid cooler handles the CPU thermal output during extended sessions. The Thermaltake Smart 850W 80 PLUS Bronze power supply uses Japanese main capacitors and a 140mm fan rated for low noise. Protection circuits cover over voltage, under voltage, over power and short circuit events. The Corsair 4000D case provides internal airflow paths for the radiator and components.

Compatibility checklist

Verify that your monitors accept HDMI or USB4 video input because no discrete graphics card is installed. The motherboard offers two USB4 ports at 40Gbps, one USB 10Gbps port, three USB 5Gbps ports and four USB 2.0 ports on the rear panel. Network connectivity includes Intel 2.5Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4. Four memory slots are populated to reach 128GB with a 192GB maximum supported capacity.

Questions about this item

How quiet is the 240mm liquid cooler and 140mm PSU fan when the Ryzen 9 9900X3D runs all day?

The 240mm Quiet Edition AIO and the Thermaltake 850W unit with its 140mm fan are both described as ultra-quiet, keeping noise low under sustained load.

What display cable do I need for the integrated Radeon graphics?

The motherboard rear I/O provides one HDMI port and two USB4 ports that carry video, so a standard HDMI cable or a USB4-to-DisplayPort adapter will work.

Will my existing SATA SSDs and 3.5-inch hard drives fit inside the Corsair 4000D case?

Yes, the case has two internal 3.5-inch bays, two 2.5-inch bays and the motherboard offers four SATA 6Gb/s ports for additional drives.
