System Overview

This business desktop pairs a 12-core AMD Ryzen 9 9900X processor with 64GB of DDR5 memory and an Nvidia RTX A400 graphics card. A 240mm liquid cooler handles CPU thermals inside an Antec P20 mid-tower case. Windows 11 Pro 64-bit is pre-installed for immediate deployment in professional environments.

Compatibility Check

Verify that your monitors accept Mini DisplayPort inputs or plan for adapters, as the RTX A400 provides four MiniDP outputs. The motherboard offers rear USB4, 10Gbps and 5Gbps ports plus front-panel USB 3.0 and USB 3.2 Gen 2 Type-C connections. Ensure your network infrastructure can utilise the onboard 2.5GbE and Wi-Fi 7 wireless capability.

Build Integration

Dual 4TB Samsung 990 PRO NVMe drives deliver up to 7450 MB/s read and 6900 MB/s write speeds for active workloads, while a 10TB hard drive with 256MB cache provides bulk storage. The 750W 80 PLUS Bronze power supply feeds all components, and the case includes three 120mm front fans alongside the liquid cooler. Four M.2 slots and multiple SATA ports remain available for future expansion.
