12-Core Ryzen 9 Workstation

This Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 128GB of DDR5 memory and a Radeon RX 9070 XT graphics card. The system ships with Windows 11 Pro installed and a 1TB Samsung 990 PRO NVMe drive. It targets professionals who need strong multi-threaded compute and GPU acceleration in a single liquid-cooled chassis.

X870 Motherboard Expansion

The TUF X870-PLUS board provides four memory slots with 192GB maximum capacity and four M.2 connectors for additional NVMe storage. Rear I/O includes two USB4 ports at 40Gbps, three 10Gbps ports and four 5Gbps ports. Internal bays accept two 3.5-inch and two 2.5-inch drives, while the 850W 80 PLUS Bronze PSU delivers protected power to all components.

240mm AIO Thermal Management

A 240mm quiet-edition liquid cooler handles the CPU under sustained workloads while front-mounted 140mm PWM fans move air through the tempered-glass case. The Thermaltake Smart power supply uses a Japanese main capacitor and a low-noise 140mm fan. This cooling arrangement keeps clock speeds stable during long rendering or compute sessions without excessive acoustic output.

Questions about this item

Will the 240 mm liquid cooler keep the 12-core Ryzen 9 9900X3D from throttling during long render jobs?

The 240 mm Quiet Edition AIO is designed for the 9900X3D's thermal output; its 140 mm PWM fans and liquid loop move heat away from the 128 MB L3 cache and 12 cores so sustained clocks stay high.

How loud is the system when the RX 9070 XT and CPU run flat-out for hours?

The 140 mm front PWM fans and the AIO's ultra-quiet 140 mm fan run at low RPM under load, while the Thermaltake Smart 850W supply's 140 mm fan stays quiet thanks to Bronze efficiency and Japanese capacitors.

What display cables must I already own to use the Radeon RX 9070 XT?

The RX 9070 XT 16GB card uses standard DisplayPort and HDMI outputs; have the matching cables for your monitor ready because none are included in the box.
