Ready-to-run AI workstation

The Adamant Custom desktop ships with Windows 11 Pro installed on a 2 TB Samsung 990 PRO NVMe drive and 192 GB of DDR5 memory. A 24-core Intel Core i9-14900K and an Nvidia GeForce RTX 5090 with 32 GB of video memory handle rendering, modelling and AI learning workloads out of the box. Liquid cooling and a 1200 W 80 PLUS Gold power supply keep the system stable under sustained load.

Who this suits and who should look elsewhere

Content creators, engineers and researchers who need maximum CPU threads, GPU memory and system RAM in a single pre-built chassis will benefit from this configuration. Buyers who only need 1080p gaming performance, a smaller memory footprint or a compact form factor should consider a different system.

The specification that decides fit

The 192 GB DDR5 capacity is the limiting factor; if your datasets or virtual machines require more system memory than this, the workstation cannot be expanded beyond the installed amount.

Questions about this item

How does the 24-core i9-14900K behave once it is inside this liquid-cooled chassis?

The 24-core Intel Core i9-14900K runs at a 3.2 GHz base clock and can boost up to 6.00 GHz. A 360 mm liquid cooler keeps temperatures in check during sustained rendering or AI workloads.

What does the Z790 chipset and PCIe 4.0 x4 link mean for the Samsung 990 PRO SSD in daily use?

The Z790 motherboard provides a PCIe 4.0 x4 connection to the M.2 slot, letting the 2 TB Samsung 990 PRO reach up to 7450 MB/s read and 6900 MB/s write speeds.

Will the Corsair 4000D case and 1200 W power supply physically accommodate the RTX 5090 and 360 mm radiator?

The Corsair 4000D measures 490 x 239 x 486 mm and supports a 360 mm radiator up front. The Thermaltake 1200 W 80 PLUS Gold unit supplies ample power for the RTX 5090 and full system.
