Core and cooling

This Adamant Custom gaming desktop pairs a 24-core Intel Core Ultra 9 285K with a 360 mm liquid cooler. The processor reaches up to 5.70 GHz and is mounted on a Gigabyte Z890 Eagle motherboard with LGA 1851 socket. A 1200 W 80 PLUS Gold power supply feeds every component.

Storage scale and AI readiness

The system ships with 32 GB of DDR5 memory, expandable to 192 GB across four slots. Dual 4 TB Samsung 990 PRO NVMe drives provide 8 TB of fast solid-state space, while a 10 TB hard drive with 256 MB cache adds bulk capacity. Windows 11 Pro and the RTX 5090 make it AI-ready for local inference workloads. Buyers who need more than 8 TB of NVMe storage or multiple graphics cards should look elsewhere.

Connectivity and build fit

Rear I/O includes USB4 Type-C, multiple USB 3.2 and 2.0 ports, 2.5 Gbps Ethernet and Wi-Fi 7 with Bluetooth 5.4. The tower case measures 447 x 215 x 469 mm and offers front USB 3.2 Gen 2x2 Type-C, two USB 3.0 and audio jacks. Internal bays accept two 3.5 inch and two 2.5 inch drives, while four M.2 connectors and four SATA ports remain available for future expansion.

Questions about this item

What DDR5 memory capacity is already installed, and how many total slots does the board provide for future upgrades?

The system ships with 32 GB of DDR5 installed across four total slots, leaving room to expand up to the 192 GB maximum supported by the Z890 EAGLE motherboard.

Will my existing SATA 6 Gb/s hard drives and 2.5 Gbps Ethernet cable work with this desktop?

Yes — the motherboard includes four SATA 6 Gb/s ports and an Intel 2.5 Gb Ethernet controller, so current drives and wired network cables connect directly without adapters.

How can I confirm the liquid cooler and RTX 5090 are running correctly after first boot?

Enter the UEFI to verify the 360 mm AIO pump speed and CPU temperature, then open GPU-Z or Task Manager to see the RTX 5090 detected with its 32 GB VRAM and driver version.
