Built for CAD and AI workloads

This business desktop pairs a 12-core Ryzen 9 9900X with 64GB of DDR5 memory and an Nvidia RTX PRO 4000 Blackwell graphics card. The configuration targets engineers and researchers who need certified drivers for SolidWorks modelling and local AI learning tasks. Windows 11 Pro 64-bit ships pre-installed. The 8TB NVMe array and 10TB hard drive provide fast active-project space plus deep archival capacity.

Standard ATX assembly with liquid cooling

The Antec P20 mid-tower uses common ATX mounting points and includes a 240mm liquid cooler pre-fitted to the AM5 socket. Builders should verify that the 850W power supply cables reach the X870 motherboard's 12VHPWR connector for the GPU. The four M.2 slots are populated with two 4TB drives, leaving no room for additional NVMe storage without removing an existing module. Front-panel USB 3.2 Gen 2 Type-C and dual USB 3.0 ports connect to standard internal headers.

PCIe 4.0 storage ceiling and 192GB memory limit

The X870 chipset links the two Samsung 990 PRO SSDs through PCIe 4.0 x4 lanes, capping sequential throughput at the drive's rated 7450 MB/s read and 6900 MB/s write. The platform supports up to 192GB of DDR5 across four DIMM slots, so the current 64GB kit can be tripled. Network connectivity tops out at 2.5GbE wired and Wi-Fi 7 wireless. The 850W Bronze-rated PSU sets the practical power envelope for future GPU upgrades.

Questions about this item

How can I verify the liquid cooler is running correctly after first boot?

The 240 mm AIO quiet edition cooler should show pump RPM and coolant temperature in the BIOS hardware monitor or the motherboard vendor utility, and the CPU should stay near 4.4 GHz under load without thermal throttling.

Which components are included and which must be purchased separately?

The system includes the Antec P20 case, X870-PLUS TUF motherboard, 850 W 80 PLUS Bronze PSU, 64 GB DDR5, two 4 TB Samsung 990 PRO NVMe drives, 10 TB HDD, RTX PRO 4000 Blackwell 24 GB GPU, Wi-Fi 7, Windows 11 Pro 64-bit, and front-panel USB 3.0, USB 3.2 Gen 2 Type-C and audio ports. A monitor is not included.

Should I choose the 64 GB DDR5 configuration or plan for the 192 GB maximum?

The board supports up to 192 GB DDR5, so the supplied 64 GB leaves three slots free for future expansion if workloads such as large SolidWorks assemblies or AI training datasets grow beyond the current capacity.
