Adamant Custom 12-Core Liquid Cooled Gaming PC

This desktop combines a 12-core Ryzen 9 9900X3D processor with an RTX 5080 graphics card, 32GB DDR5 memory and a 2TB NVMe SSD. It targets enthusiasts and professionals who need high single-thread speed and large video memory for creative workloads or competitive play. The system ships with Windows 11 Pro installed.

240mm AIO installation and common issues

The closed-loop cooler arrives pre-filled and mounted to the CPU, so no tubing work or coolant handling is required. Builders only need to connect the pump and fan headers to the X870 motherboard. The most frequent oversight is leaving the protective shipping bracket on the radiator or forgetting to plug the pump header, which causes high idle temperatures.

Check case clearance and power connections

Verify that your workspace can accommodate a chassis measuring 447 mm deep, 215 mm wide and 469 mm high. The 1000W 80 PLUS Gold PSU uses standard ATX cables; confirm your mains lead matches the local plug type. The motherboard offers four DDR5 slots with a 192 GB maximum, two 3.5-inch and two 2.5-inch drive bays, plus four M.2 connectors for future storage expansion.

Questions about this item

How do I confirm the 240 mm liquid cooler is keeping the Ryzen 9 9900X3D within safe temperatures after assembly?

Enter the BIOS on first boot and watch the CPU temperature at idle; it should sit well below the 5.50 GHz boost ceiling, then run a sustained load to verify the 240 mm AIO maintains stable readings.

Which components ship inside the case and which items such as a monitor or keyboard must be sourced separately?

The desktop arrives fully assembled with the X870 motherboard, 12-core CPU, 32 GB DDR5, 2 TB Samsung 990 PRO SSD, RTX 5080 16 GB graphics card, 1000 W Gold PSU, 240 mm liquid cooler, Wi-Fi 7 and Windows 11 Pro; peripherals are not included.

Should I choose the 32 GB DDR5 configuration or plan to populate the remaining slots up to the 192 GB maximum later?

The board provides four DDR5 slots with 32 GB installed; if your workloads need more than 32 GB you can add matching modules later to reach the 192 GB limit.
