Workstation CPU and memory

The Adamant Custom desktop pairs a twelve-core Ryzen 9 9900X processor with 128GB of DDR5 memory, reaching up to 5.20 GHz and 96 MB of L3 cache. It targets engineers, modellers and AI researchers who need high single-thread speed and large memory capacity for SolidWorks assemblies or local model training. The system ships with Windows 11 Pro and a 240mm liquid cooler. Buyers who need more than 192GB of RAM or a second GPU should look elsewhere.

Storage upgrade path

A 4TB Samsung 990 PRO NVMe drive delivers sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec for active projects, while a 10TB hard drive with 256MB cache provides bulk capacity for archives and datasets. The X870 motherboard adds four M.2 connectors and two SATA 6Gb/s ports for further expansion. Users who require faster-than-PCIe-4.0 throughput or enterprise-grade endurance are not served by this configuration.

Sustained thermal behaviour

The Antec P10 FLUX case uses sound-dampening panels and a 140mm PSU fan alongside front and rear 120mm fans to move air over the RTX PRO 5000 Blackwell 48GB card and CPU radiator. An 850W 80 PLUS Bronze supply with Japanese main capacitors powers the build under continuous compute loads. Workloads that exceed the single 850W rail or demand dual-GPU cooling fall outside the thermal envelope.

Questions about this item

What case dimensions and drive bays does the Antec P10 FLUX chassis provide for this workstation?

The Antec P10 FLUX mid-tower measures 477 mm deep, 220 mm wide and 486 mm high. It offers one external 5.25-inch bay, three internal 3.5-inch bays and three 2.5-inch bays for storage expansion.

How is the 240 mm AIO liquid cooler mounted on the X870-PLUS TUF motherboard, and what step is often missed?

The cooler uses the standard AM5 retention frame on the X870-PLUS TUF board. The step people miss is removing the protective film from the cold-plate before securing the pump block.

Which components in this build may need replacement first, and what are their rated limits?

The Thermaltake Smart 850 W PSU carries an 80 PLUS Bronze rating and Japanese main capacitors. The Samsung 990 PRO 4 TB NVMe SSD is rated for up to 7450 MB/s read and 6900 MB/s write. The 10 TB HDD includes a 256 MB cache.
