System overview

This Adamant Custom business desktop pairs a 12-core AMD Ryzen 9 9900X processor with 64 GB of DDR5 memory and a 240 mm liquid cooler. A 4 TB NVMe drive and a 10 TB hard drive provide fast boot and deep archive storage. The Nvidia RTX A400 graphics card adds four Mini DisplayPort outputs for multi-monitor work. Windows 11 Pro 64-bit is pre-installed.

Ideal fit

The machine suits professionals who need strong single-thread speed, quiet cooling and large local storage for content creation or data analysis. Buyers who require more than 4 GB of video memory or multiple full-size DisplayPort connectors should consider a different graphics configuration. The 750 W power supply and mid-tower chassis limit future high-wattage GPU upgrades.

Deciding specification

The RTX A400 includes 4 GB of GPU memory and four Mini DisplayPort outputs. This capacity drives up to four 4K displays but restricts heavy 3D rendering or large-model AI workloads. Confirm that your software fits within this video-memory budget before ordering.

Questions sur cet article

What bandwidth does the PCI Express x16 slot provide for the RTX A400 GPU?

The graphics interface is PCI Express x16, so the RTX A400 runs at full x16 lane width for its 4 GB frame buffer and four Mini DisplayPort outputs.

Which physical bays and clearances does the Antec P10 FLUX case require for the 10 TB hard drive and 240 mm liquid cooler?

The case offers three internal 3.5" bays for the 10 TB drive and a front mount sized for a 240 mm radiator with three 120 mm fans already installed.

How is the 240 mm AIO cooler mounted on the AM5 socket, and what step is often missed?

The cooler uses the standard AM5 retention frame; the step people miss is removing the protective film from the cold-plate before securing the pump block.
