Workstation for compute-heavy tasks

This Adamant Custom business desktop pairs a 12-core AMD Ryzen 9 9900X processor with 128GB of DDR5 memory and an Nvidia RTX A400 graphics card. The system ships with Windows 11 Pro and targets professionals who need strong multi-threaded performance for rendering, simulation or data-analysis workloads.

Sustained load with liquid cooling

A 240mm liquid cooler keeps the CPU at stable clocks during long compile jobs or overnight batches, while the 750W power supply delivers consistent power without thermal throttling. The Samsung 990 PRO NVMe drive maintains sequential reads up to 7450 MB/s and writes up to 6900 MB/s, so large project files stay responsive throughout extended sessions.

Check your display and peripheral needs

The RTX A400 provides four Mini DisplayPort outputs, so verify that your monitors accept this connector or budget for adapters. The motherboard offers USB4, 20Gbps, 10Gbps and 5Gbps ports plus 2.5G Ethernet and Wi-Fi 7; confirm your existing docks, storage enclosures and network gear can use these interfaces.

Perguntas sobre este artigo

How loud does the 240 mm liquid cooler and the 140 mm PSU fan get under sustained load?

The CPU uses a 240 mm quiet-edition liquid cooler and the 750 W PSU has a 140 mm ultra-quiet fan, both designed for low noise during long workstation sessions.

Which display cables must I already own to connect monitors to the four Mini DisplayPort outputs on the RTX A400?

The RTX A400 provides four Mini DisplayPort connectors, so you need Mini DisplayPort cables or Mini DisplayPort-to-DisplayPort/HDMI adapters for each monitor you plan to attach.

Can the X870 motherboard still run my older SATA SSDs and 3.5-inch hard drives alongside the new NVMe boot drive?

Yes, the board includes two SATA 6 Gb/s ports and the case has two internal 3.5-inch bays, so legacy SATA drives install directly beside the 1 TB NVMe SSD.
