Adamant Custom
A 24-core Intel Core Ultra 9 285K desktop with 32GB DDR5, 4TB NVMe storage and liquid-cooled RTX 5090 graphics for 4K gaming and AI workloads
This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with an Nvidia GeForce RTX 5090 graphics card. It ships with 32GB of DDR5 memory and a 4TB NVMe SSD running Windows 11 Pro. A 360mm liquid cooler and 1200W 80 PLUS Gold power supply support the high-wattage components inside a mid-tower chassis.
The configuration suits users who need maximum single-thread speed and 32GB of video memory for rendering, simulation or high-refresh 4K play. Buyers who want more than 32GB of system memory or additional internal drive bays should look at something else. The four memory slots allow expansion up to 192GB if workloads grow.
The system arrives fully assembled so installation is limited to plugging in power, display and peripherals. Front-panel USB 3.2 Gen 2x2 Type-C and rear USB4 Type-C ports handle modern devices. The 2.5Gbps LAN and Wi-Fi 7 wireless provide network flexibility. Ensure the 447mm case depth fits the intended workspace before ordering.

Yes, the board uses DDR5 only and ships with 32 GB installed across four slots. You can add up to 192 GB total using DDR5 kits.
The Z890M AORUS board provides four SATA 6 Gb/s ports supporting RAID 0, 1, 5 and 10, so existing SATA drives connect directly.
Check that the 360 mm radiator fans spin, feel warm exhaust air from the top vent, and confirm CPU temperatures stay low in the BIOS or monitoring software.
