Adamant Custom
Liquid-cooled tower with a 24-core Intel Core Ultra 9 285K, 32 GB DDR5, 8 TB NVMe storage and an RTX 5090 GPU for high-end gaming and AI workloads
The Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with an Nvidia GeForce RTX 5090 graphics card. Thirty-two gigabytes of DDR5 memory and an 8 TB NVMe array handle large media projects and modern games. Windows 11 Pro ships pre-installed on the tower system.
A TUF Gaming Z890 motherboard provides the LGA 1851 socket, four DDR5 slots supporting up to 192 GB, and four M.2 connectors for future storage expansion. Rear I/O includes Thunderbolt 4, 20 Gbps and 10 Gbps USB, plus 2.5 Gbps Ethernet. Wi-Fi 7 and Bluetooth 5.4 handle wireless connectivity without extra cards.
A 360 mm quiet-edition liquid cooler dissipates CPU heat during long render or compile sessions. The Thermaltake Toughpower 1200 W 80 PLUS Gold unit delivers stable power with Japanese capacitors and protections against over-voltage, under-voltage, over-power and short-circuit events. Case airflow uses 140 mm fans rated at 30 dBA for consistent cooling.
