Workstation build for CAD and AI

This business desktop combines a twelve-core AMD Ryzen 9 9900X processor with 192GB of DDR5 memory and an Nvidia RTX PRO 4500 Blackwell graphics card. It targets engineers and researchers who need strong single-thread speed and professional GPU drivers for SolidWorks modelling and AI learning workloads.

Memory capacity and storage headroom

The system ships with the maximum supported 192GB of DDR5, leaving no room for further memory upgrades. A 4TB NVMe SSD provides fast project storage while a 10TB hard drive adds deep capacity for archives; both can be expanded using the motherboard's additional M.2 and SATA connections.

Platform interface limits

The AM5 motherboard supplies two USB4 ports at 40Gbps, three USB 10Gbps ports and four USB 5Gbps ports for peripherals. Network access relies on 2.5G Ethernet and Wi-Fi 7 wireless. Four M.2 slots and two SATA 6Gbps ports set the ceiling for further NVMe or hard-drive expansion.

Questions about this item

Will the X870 motherboard's four M.2 slots accept my existing NVMe drives alongside the new 4TB Samsung 990 PRO?

Yes, the X870-PLUS TUF board provides four M.2 connectors so you can keep current NVMe drives and add the supplied 4TB Samsung 990 PRO PCIe 4.0x4 SSD.

How can I verify the 240 mm liquid cooler is keeping the Ryzen 9 9900X at its 4.4 GHz base clock under load?

Monitor CPU temperature and clock speed in Windows 11 Pro Task Manager or BIOS; the 240 mm Quiet Edition AIO is sized for the 12-core processor's thermal output.

Which cables and drives are included versus what I must supply for the 10 TB HDD and front-panel USB?

The 10 TB 256 MB cache HDD and 4 TB NVMe SSD come installed; SATA data and power cables are pre-routed. Front-panel USB 3.0 and USB 2.0 headers are connected to the case I/O.
