Business Desktop Workstation

The Adamant Custom tower is a liquid-cooled workstation built around a 24-core Intel Core i9-14900K processor and 32GB of DDR5 memory. It ships with Windows 11 Pro installed and includes a 1TB NVMe SSD alongside a 10TB hard drive for high-capacity storage. The system is designed for professional workloads requiring multi-threaded compute performance.

Nvidia RTX A400 4GB GPU

The graphics card provides four Mini DisplayPort outputs to drive multiple professional displays from a single slot. It is a workstation-class GPU intended for CAD, visualisation and multi-monitor productivity rather than gaming or real-time ray-tracing acceleration. Buyers needing certified drivers for ISV applications or more video memory should verify compatibility with their specific software stack.

850W Bronze PSU and Connectivity

The Thermaltake 850W 80 PLUS Bronze power supply delivers stable power with Japanese main capacitors and a 140mm low-noise fan. The Gigabyte Z790 AORUS motherboard adds Intel 2.5Gb Ethernet, Wi-Fi 6 and Bluetooth alongside extensive USB 3.2 Gen 2 and Type-C ports front and rear. Four M.2 slots and six SATA ports remain available for future storage expansion.

Questions about this item

What does the i9-14900K’s 6.00 GHz boost mean for everyday workloads?

The 24-core CPU can reach 6.00 GHz on active cores, accelerating single-threaded tasks such as compilation or large spreadsheet recalculation while the 36-thread design keeps background services responsive.

How does the PCIe 4.0 x4 link affect the Samsung 990 PRO’s 7450 MB/s read speed?

The motherboard’s M.2 slot runs at PCIe 4.0 x4, so the SSD can deliver its quoted 7450 MB/s sequential read and 6900 MB/s write without bottleneck.

Will the 360 mm liquid cooler fit in the Antec P20 case?

Yes, the 469 mm deep chassis supports a 360 mm radiator in the front, and the build already includes the 360 mm Quiet Edition AIO mounted there.
