Workstation CPU and memory

The system centres on a 12-core AMD Ryzen 9 9900X3D processor reaching 4.4 GHz base frequency with 128 MB L3 cache. It pairs with 128 GB of DDR5 memory on an X870 motherboard that supports up to 192 GB total capacity. This configuration targets engineers and analysts running large SolidWorks assemblies or multi-physics simulations.

Sustained thermal behaviour

A 240 mm liquid cooler handles the CPU while the Corsair 4000D chassis moves air through a 140 mm fan. The 850 W 80 PLUS Bronze power supply delivers stable output with over-voltage, under-voltage, over-power and short-circuit protection. Components stay within thermal limits during extended compute jobs without acoustic intrusion.

Storage and connectivity ceilings

Two 4 TB Samsung 990 PRO drives provide 8 TB of NVMe capacity with sequential reads up to 7450 MB/s and writes up to 6900 MB/s. A 10 TB hard drive adds bulk retention. Rear I/O includes two USB4 ports at 40 Gbps, three 10 Gbps ports, four 5 Gbps ports and one 2.0 port alongside 2.5 GbE and Wi-Fi 7 wireless.

Questions about this item

How loud is the 240mm liquid cooler and 140mm PSU fan when the Ryzen 9 9900X3D runs at full load all day?

The 240mm Quiet Edition AIO and Thermaltake 850W PSU with its 140mm ultra-quiet fan are designed for low noise during sustained workloads.

Which display cables must I already own to connect a monitor to the RTX PRO 4500 Blackwell?

The GPU provides standard DisplayPort and HDMI outputs; have the matching cable for your monitor ready.

Can I keep my existing SATA SSDs and 3.5-inch hard drives when moving to this X870 motherboard?

Yes, the board includes four SATA 6Gb/s ports and the Corsair 4000D case has two internal 3.5-inch bays for them.
