12-Core Liquid-Cooled Workstation

The Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 128GB of DDR5 memory and a 4TB NVMe SSD. A 360mm liquid cooler and 850W power supply support the high core count in a mid-tower chassis. The system ships with Windows 11 Pro and integrated Radeon graphics for immediate use.

Sustained Load Behaviour

The 360mm Quiet Edition liquid cooler is designed to dissipate heat continuously during long render or compile sessions. The 850W 80 PLUS Bronze unit with Japanese main capacitors delivers stable power without thermal throttling. Front 120mm intake fans and dust filters maintain airflow over extended periods.

Interface Practical Limits

Integrated Radeon graphics drive displays via HDMI and two USB4 ports at 40Gbps each. Rear I/O also provides USB 20Gbps, 10Gbps and 5Gbps connections alongside Intel 2.5Gb Ethernet. Wi-Fi 7 and Bluetooth 5.4 handle wireless traffic, while four M.2 slots and two SATA ports allow future storage expansion.

Questions about this item

How loud is the 360 mm liquid cooler and 850 W PSU during long sessions?

The 360 mm Quiet Edition AIO and Thermaltake Smart 850 W PSU both use low-noise fans — a 140 mm unit on the PSU and 120 mm fans on the radiator — keeping acoustic levels low under sustained load.

Which display cables do I need for the integrated Radeon graphics outputs?

The motherboard rear I/O provides one HDMI port and two USB4 Type-C ports that carry video; connect a monitor with HDMI or a USB-C/DisplayPort cable to either USB4 port.

Will my existing PCIe 3.0 NVMe drive work in the spare M.2 slots?

Yes — the X870 motherboard includes four M.2 connectors that support PCIe 4.0 and are backward compatible with PCIe 3.0 NVMe SSDs.
