Built for intensive workloads

This business desktop combines a 12-core AMD Ryzen 9 9900X processor with 64GB of DDR5 memory and an Nvidia RTX PRO 4000 Blackwell GPU. It targets engineers, designers and AI researchers who need reliable multi-threaded compute and professional graphics certification in a single workstation.

Storage and memory layout

A 4TB Samsung 990 PRO NVMe drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s for active project files. The 10TB hard drive with 256MB cache adds bulk capacity for archives, while four M.2 slots on the motherboard allow future expansion up to 192GB of total system memory.

Connectivity and power envelope

The system relies on PCI Express x16 for the graphics card and PCIe 4.0 x4 for the primary SSD, limiting throughput to those lane counts. Rear I/O includes 2.5G Ethernet and Wi-Fi 7 wireless, while the 850W 80 PLUS Bronze power supply caps total sustained draw, constraining future GPU upgrades that exceed its headroom.

Questions about this item

Will the 240 mm liquid cooler need refilling or pump replacement down the line?

The 240 mm AIO is a sealed maintenance-free loop; no refills are required and the pump is rated for continuous operation.

Which component hits its thermal ceiling first when the Ryzen 9 9900X runs at 5.20 GHz all day?

The CPU package temperature will reach its limit before the GPU or VRM, so the liquid cooler and case airflow determine sustained boost duration.

How loud does the 140 mm PSU fan and the three 120 mm front fans get under full load?

The PSU uses an ultra-quiet 140 mm fan and the case includes sound-dampening panels, keeping overall noise low even at maximum cooling demand.
