Workstation Core

The Adamant Custom business desktop centres on a 24-core Intel Core i9-14900K processor paired with 128GB of DDR5 memory. A liquid-cooled tower chassis houses an NVIDIA RTX A4000 graphics card, 1TB NVMe storage and a 10TB hard drive. Windows 11 Pro ships pre-installed for immediate deployment in engineering and modelling workflows.

Upgrade Path

This configuration replaces older multi-threaded workstations that struggle with large assemblies or simulation datasets. The jump is worth it when CPU core count, GPU memory bandwidth and fast local storage become simultaneous bottlenecks. Builders who need a second graphics card or more than four memory slots should evaluate alternative platforms.

Capacity Headroom

The 128GB DDR5 kit occupies four slots with a 192GB ceiling for future expansion. The 1TB NVMe drive delivers read speeds up to 7450 MB/sec and write speeds up to 6900 MB/sec for active project files. The 10TB hard drive provides deep archival capacity for completed models and datasets.

Questions about this item

Will the 469 mm deep Antec P20 mid-tower fit on my desk shelf?

The case measures 469 mm deep, 220 mm wide and 490 mm high, so check your shelf depth against 469 mm before ordering.

Does the 360 mm AIO liquid cooler need any extra mounting steps on the Z790 AORUS board?

The cooler uses the standard LGA 1700 bracket included with the motherboard; the step often missed is tightening the four corner screws in a cross pattern to seat the cold plate evenly.

When will the 850 W Thermaltake Smart PSU likely need replacement?

Quality 80 PLUS Bronze units typically run 5–7 years before capacitor aging warrants a swap; watch for coil whine or random shutdowns under load.
