Adamant Custom 24-Core Ultra 9 285K 128GB DDR5 2TB NVMe 10TB HDD RTX 5090 32GB gaming PC

24-Core Ultra 9 Workstation

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with 128GB of DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. It targets professionals who need high parallel throughput for rendering, modelling and AI learning workloads. The system ships with Windows 11 Pro installed and includes a 2TB NVMe SSD plus a 10TB hard drive for large project libraries.

Build Integration

The Gigabyte Z890M AORUS motherboard provides four memory slots with a 192GB ceiling, leaving headroom for future expansion. A 1200W 80 PLUS Gold power supply delivers power to the CPU and GPU through a single unit, while the case offers two 3.5-inch and two 2.5-inch internal bays for additional storage. Rear I/O includes USB4 Type-C, 2.5Gbps Ethernet and Wi-Fi 7 connectivity, reducing the need for extra add-in cards.

Thermals and Power

A 360mm quiet-edition liquid cooler handles the CPU, supported by two 140mm PWM front fans that move air through the tempered-glass chassis. The power supply uses a Japanese main capacitor and a low-noise 140mm fan, with protection against over-voltage, under-voltage, over-power and short-circuit events. In typical operation the cooling solution keeps acoustic output low while maintaining thermal headroom for sustained compute tasks.
