Built for Professional Workloads

This business desktop combines an 8-core AMD Ryzen 7 9800X3D processor with 128GB DDR5 memory and an Nvidia RTX A400 graphics card. The configuration targets workstation tasks such as CAD, rendering and multi-application workflows. A 1TB NVMe SSD and a 10TB hard drive provide fast boot and deep archival storage. Windows 11 Pro 64-bit is pre-installed.

Ready to Deploy

The system arrives fully assembled with a 240mm liquid cooler and an 850W 80 PLUS Bronze power supply. Mini DisplayPort outputs on the GPU require compatible cables or adapters for standard monitors. The motherboard includes four M.2 slots and multiple USB headers for future expansion. No component installation is required on arrival.

Verify Your Peripherals

Ensure your displays support Mini DisplayPort or budget for active adapters. The chassis measures 477 x 220 x 486 mm, so confirm desk or rack space. Network infrastructure should accommodate 2.5G Ethernet and Wi-Fi 7 for full bandwidth. The 10TB drive uses a standard 3.5-inch SATA bay already populated.

Questions about this item

How can I verify the Ryzen 7 9800X3D is running at its 4.7 GHz base clock and 96 MB L3 cache after assembly?

Open Task Manager’s Performance tab or use CPU-Z to confirm the processor shows 8 cores, 16 threads, a 4.7 GHz base frequency and 96 MB of L3 cache.

What components are included in the box and which items such as a display must be purchased separately?

The system ships complete with the Antec P10 FLUX case, 240 mm liquid cooler, PRIME X870-P motherboard, 128 GB DDR5, 1 TB Samsung 990 PRO NVMe, 10 TB HDD, RTX A400 4 GB GPU, 850 W PSU and Windows 11 Pro; a monitor is not included.

Which memory capacity should I choose between the standard 128 GB DDR5 and the maximum supported 192 GB?

The build already provides 128 GB DDR5; select 192 GB only if your workloads such as large-scale simulation or heavy virtualization regularly exceed that amount.
