Built for SolidWorks and CAD modelling

This workstation pairs a 12-core Ryzen 9 9900X3D with an NVIDIA RTX PRO 4000 Blackwell GPU carrying 24GB of video memory. The combination targets engineers and designers who need certified driver stability for large assemblies and simulation workloads. Windows 11 Pro 64-bit is pre-installed. Buyers who need more than 192 GB of system memory or a second graphics card should look elsewhere.

Liquid-cooled CPU and 850W Bronze power supply

A 240mm quiet-edition AIO handles the processor while a 140mm fan in the Thermaltake Smart 850W unit keeps PSU noise low. The case ships with three 120mm RGB fans for chassis airflow. Power protection covers over-voltage, under-voltage, over-power and short-circuit events. The 80 PLUS Bronze rating confirms baseline efficiency.

High-speed storage, Wi-Fi 7 and extensive USB

A 1TB Samsung 990 PRO NVMe drive delivers read speeds up to 7450 MB/s and write speeds up to 6900 MB/s alongside a 10TB HDD with 256MB cache. The TUF X870-PLUS motherboard adds two USB4 40Gbps Type-C ports, three 10Gbps ports, four 5Gbps ports and one USB 2.0 port at the rear. Front-panel I/O includes two 5Gbps USB ports and a combo audio jack. Wi-Fi 7 2x2 and Intel 2.5Gb Ethernet provide wireless and wired connectivity.

Questions about this item

How is the 240 mm liquid cooler mounted on the AM5 socket?

The 240 mm Quiet Edition AIO uses the standard AM5 retention bracket; the step people miss is removing the motherboard’s plastic back-plate before tightening the four spring-loaded screws in a cross pattern.

Which components will need replacement first during the workstation’s life?

The 140 mm PSU fan and the two 120 mm front case fans are the only moving parts besides the pump; expect to swap them when noise or airflow drops.

What thermal limit appears first when the Ryzen 9 9900X3D runs sustained all-core loads?

The CPU hits its 5.50 GHz boost ceiling and the 240 mm radiator saturates, so package power throttles before the 850 W PSU or 24 GB VRAM become bottlenecks.
