Adamant Custom 24-Core Ultra 9 285K 192GB DDR5 RTX 5090 32GB Gaming PC

24-Core Ultra 9 285K Workstation

This desktop pairs a 24-core Intel Core Ultra 9 285K processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card carrying 32GB of video memory. It is built for professionals who run rendering, modelling or AI-learning workloads that demand both high thread counts and large GPU frame buffers. The system ships with Windows 11 Pro and a 1TB Samsung 990 PRO NVMe drive alongside a 10TB hard drive. Buyers who need more internal drive bays than the two 3.5-inch and two 2.5-inch slots provided should look elsewhere.

Sustained Load Behaviour

The CPU operates at a 3.7GHz base frequency and can reach 5.70GHz under load while the 360mm liquid cooler keeps temperatures in check during long compile or training runs. A 1200W 80 PLUS Gold power supply delivers stable current to the GPU and CPU without throttling. The Z890 motherboard provides three M.2 connectors and four SATA ports for additional high-speed storage if the project grows. Users who rely on multi-GPU configurations will not find a second card slot on this platform.

Thermals Noise and Power

Liquid cooling for the processor and a 140mm ultra-quiet fan in the power supply limit acoustic output while the tower case moves air through two front 140mm PWM fans. The 1200W unit includes over-voltage, under-voltage, over-power and short-circuit protection. Front-panel I/O offers USB 3.2 Gen 2x2 Type-C, two USB 3.0 ports and audio jacks; the rear adds USB4 Type-C, USB 3.2 Gen 2, four USB 3.2 Gen 1 and four USB 2.0 connections. Networking uses Intel 2.5Gb Ethernet and Wi-Fi 7 with Bluetooth 5.4.
