Adamant Custom
A 24-core Intel Core Ultra 9 285K desktop with 64GB DDR5, 1TB NVMe SSD, liquid cooling, Wi-Fi 7 and Bluetooth 5.4 running Windows 11 Pro
The Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K with a 360 mm liquid cooler in a tower chassis. Sixty-four gigabytes of DDR5 and a 1 TB NVMe drive provide a responsive platform for content creation and multitasking. Integrated graphics handle display output through USB4 and DisplayPort connections.
Four memory slots support up to 192 GB of DDR5, so the installed 64 GB leaves three slots open for future expansion. The Z890 motherboard supplies three M.2 connectors and four SATA ports for additional storage. Rear I/O includes USB4, USB 3.2 Gen 2, USB 3.2 Gen 1 and USB 2.0 ports alongside 2.5 Gb Ethernet and Wi-Fi 7.
The 1 TB Samsung 990 PRO delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s for fast project loading. An 850 W 80 PLUS Bronze power supply with Japanese main capacitors powers the CPU at up to 5.70 GHz and all integrated components. Internal bays accept two 3.5-inch and two 2.5-inch drives for further capacity growth.
