Ready-to-Go 24-Core Workstation

The Adamant Custom desktop arrives fully assembled with a 24-core Intel Core Ultra 9 285K processor, 32GB of DDR5 memory and an 8TB NVMe array built from two Samsung 990 PRO drives. Windows 11 Pro is pre-installed and the system is liquid-cooled by a 360mm AIO, so creators and gamers can start working immediately without building or configuring components.

Installation Is Plug-and-Play

Because the CPU, GPU, memory and storage are already mounted inside the tempered-glass tower, the only physical steps are connecting a display, keyboard, mouse and power cable. The 1200W 80 PLUS Gold supply handles the RTX 5090 and CPU without extra cables, and the motherboard’s rear I/O includes USB4, 2.5Gbps LAN and Wi-Fi 7 antennas. No driver hunting is required — the OS ships with current Nvidia and Intel drivers installed.

Check Power, Space and Expansion Needs

Verify your wall outlet can deliver sufficient current for a 1200W supply and that the 447 x 215 x 469 mm tower fits your desk or floor area. The Z890M AORUS board offers two free DDR5 slots for future upgrades up to 192GB, one spare M.2 connector and internal 3.5-inch bays for additional hard drives. If you need more than the two front USB 3.0 ports or the single front USB 3.2 Gen 2x2 Type-C, plan for a powered hub or rear-panel routing.

Questions about this item

How do I verify the liquid cooler is running after first boot?

Enter the BIOS and confirm the CPU fan header reports RPM for the 360 mm AIO; then watch the coolant temperature settle under load in the supplied monitoring utility.

What ships inside the case and what must I add?

The tower arrives fully assembled with the Core Ultra 9 285K, 32 GB DDR5, dual 4 TB Samsung 990 PRO SSDs, RTX 5090 32 GB, 1200 W Gold PSU, Wi-Fi 7 and Windows 11 Pro; only a display, keyboard and mouse are needed.

Which SSD capacity matches the listed 8 TB total?

The configuration uses two 4 TB Samsung 990 PRO PCIe 4.0 drives in the M.2 slots, giving the 8 TB NVMe total shown in the specification.
