Adamant Custom
A 24-core liquid-cooled gaming desktop with 32 GB DDR5, 8 TB NVMe storage, WIFI7 and Bluetooth 5.4
This desktop PC is built around a 24-core Intel Core Ultra 9 285K processor running at 3.7 GHz with a 5.70 GHz boost. It ships with 32 GB of DDR5 memory and 8 TB of NVMe storage across two Samsung 990 PRO drives. The system targets professionals and enthusiasts who need high multi-threaded performance in a liquid-cooled tower.
The Gigabyte Z890M AORUS motherboard provides four DDR5 slots supporting up to 192 GB total, three M.2 connectors and four SATA ports for additional drives. Rear I/O includes USB4 Type-C, USB 3.2 Gen 2, multiple USB 3.2 Gen 1 and USB 2.0 ports, 2.5 Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4. Internal bays offer two 3.5-inch and two 2.5-inch slots. Integrated graphics handle display output via USB4 and DisplayPort, leaving PCIe lanes free for add-in cards.
A 360 mm quiet-edition AIO liquid cooler manages CPU heat while front-mounted 140 mm PWM fans move air through the tempered-glass case. The Thermaltake Smart 850 W 80 PLUS Bronze power supply uses Japanese main capacitors and a low-noise 140 mm fan with over-voltage, under-voltage, over-power and short-circuit protection. This combination keeps temperatures controlled and acoustic output low under typical workloads.
