Built for CAD and simulation workloads
This business desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with an NVIDIA RTX PRO 5000 Blackwell GPU carrying 48GB of video memory. The system ships with 128GB of DDR5 RAM, expandable to 192GB, and runs Windows 11 Pro. It targets engineers and analysts who need certified drivers and large frame buffers for SolidWorks, CAM and CAE tasks.
Replaces older single-socket workstations
The jump is worthwhile when your current machine stalls on multi-body assemblies or runs out of GPU memory during rendering. The CPU delivers up to 5.50 GHz boost with 128MB of L3 cache, while the 4TB Samsung 990 PRO NVMe drive reads at up to 7450 MB/sec and writes at up to 6900 MB/sec. A 10TB HDD with 256MB cache provides bulk project storage.
PCI Express x16 and 2.5G Ethernet set the I/O
The graphics card occupies a single PCI Express x16 slot on the PRIME X870-P motherboard. Network traffic tops out at 2.5Gbps over Intel Ethernet, with Wi-Fi 7 available for wireless links. Rear I/O includes two USB4 ports at 40Gbps, one USB 10Gbps port, three USB 5Gbps ports and four USB 2.0 ports. Internal expansion uses four M.2 connectors and two SATA 6Gb/s headers.

Questions about this item
What case dimensions and drive bays does the Antec P20 chassis provide?
The Antec P20 mid-tower measures 469 x 220 x 490 mm and offers internal bays for two 3.5"/2.5" drives plus two dedicated 2.5" slots.
How is the 240 mm liquid cooler mounted on the AM5 socket, and what step is often missed?
Attach the AM5 retention bracket supplied with the cooler, apply thermal paste, then secure the pump block; the step often missed is removing the protective film from the cold-plate before mounting.
Which components can be upgraded later and what are their limits?
Memory can be expanded to 192 GB DDR5 across four slots, the four M.2 connectors accept additional NVMe SSDs, and two SATA ports remain free for extra hard drives.
