12-Core Workstation with Integrated Graphics

The Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 192GB of DDR5 memory and 8TB of NVMe storage across two 4TB Samsung 990 PRO drives. Liquid cooling handles the CPU thermal load in a mid-tower chassis. The system targets professionals who need high core counts and large memory capacity without a discrete graphics card.

Sustained Load Behaviour

A 360mm quiet-edition liquid cooler and a 140mm PSU fan dissipate heat from the 12-core CPU during extended workloads. The 850W 80 PLUS Bronze power supply includes over-voltage, under-voltage, over-power and short-circuit protection. The Antec P20 case uses three 120mm front fans plus bottom, front and top dust filters to maintain airflow over long sessions.

Connectivity and Storage Limits

Rear I/O provides two USB4 ports at 40Gbps, three 10Gbps USB ports, four 5Gbps USB ports and one USB 2.0 port. Internal headers add one 20Gbps USB connector, one 5Gbps header and two USB 2.0 headers. The motherboard offers four M.2 slots and two SATA 6Gbps ports for further expansion. Networking uses Intel 2.5Gb Ethernet plus Wi-Fi 7 2x2 and Bluetooth 5.4.

Questions about this item

How loud and hot does the 360 mm liquid cooler keep the 12-core Ryzen 9 9900X3D when the system runs all day?

The 360 mm Quiet Edition AIO is designed for low-noise operation while handling the 12-core processor under sustained load.

What display cable or adapter do I need to use the integrated Radeon graphics on day one?

The motherboard provides one HDMI port and two USB4 ports that carry video, so a standard HDMI cable or a USB-C to DisplayPort adapter works immediately.

Will my existing SATA SSDs or hard drives connect to the X870 TUF motherboard inside this tower?

Yes, the board includes two SATA 6 Gb/s ports and the case has two internal 3.5"/2.5" bays for adding legacy drives.
