Ryzen 9 9900X workstation for CAD and AI

This business desktop pairs a twelve-core AMD Ryzen 9 9900X processor with 128GB of DDR5 memory and an Nvidia RTX PRO 4500 Blackwell graphics card. It targets engineers and researchers who need strong single-thread speed and large GPU memory for modelling, simulation and machine-learning workloads. The system ships with Windows 11 Pro and a liquid-cooled CPU.

Sustained load on liquid cooling and 850W supply

A 240mm liquid cooler keeps the CPU near its 5.20 GHz boost clock during long renders or training runs, while the 850W 80 PLUS Bronze unit delivers stable power to the 32GB GPU and dual 4TB NVMe drives. The case moves air through three front fans and dust filters to maintain thermal headroom over extended sessions. Components stay within spec without throttling.

PCIe 4.0 NVMe and 2.5G Ethernet ceiling

The two Samsung 990 PRO SSDs run at PCIe 4.0x4, capping sequential reads at 7450 MB/s and writes at 6900 MB/s. Network traffic is limited to 2.5G Ethernet or Wi-Fi 7 wireless, so large dataset transfers depend on external infrastructure. Four M.2 slots and two SATA ports allow further storage expansion within the motherboard limits.

Questions about this item

How much heat and noise does the 240 mm liquid cooler and 850 W PSU produce when the Ryzen 9 9900X runs all day?

The 240 mm Quiet Edition AIO is designed for low-noise operation, and the Thermaltake 850 W 80 PLUS Bronze PSU uses a 140 mm ultra-quiet fan to keep acoustic levels down under sustained load.

Which display cables and monitor inputs do I need to use the RTX PRO 4500 Blackwell?

The GPU connects via PCI Express x16; you must supply a monitor with compatible DisplayPort or HDMI inputs and the matching cables, as none are included.

Can I keep my existing SATA SSDs and 3.5″ hard drives inside this case?

Yes, the motherboard provides four SATA 6 Gb/s ports and the Antec P20 case has two internal 3.5″/2.5″ bays plus two 2.5″ bays for legacy drives.
