24-Core Ultra 9 Workstation

The Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with an Nvidia GeForce RTX 5090 32GB graphics card. It ships with 192GB of DDR5 memory, a 2TB Samsung 990 PRO NVMe SSD and a 10TB hard drive. Windows 11 Pro is pre-installed for immediate AI, rendering and modelling workloads.

Compatibility Checklist

Verify that your workspace can accommodate a tower measuring 447mm deep, 215mm wide and 469mm high. The system draws power from a 1200W 80 PLUS Gold supply with standard IEC input. Network infrastructure should support 2.5Gbps Ethernet or Wi-Fi 7 for full throughput. Ensure monitor cables match the GPU outputs available on the RTX 5090.

Build Integration

A 360mm liquid cooler handles the CPU thermal load while the case provides front 140mm PWM fans for chassis airflow. Four memory slots are fully populated at the 192GB maximum supported by the Gigabyte Z890 Eagle motherboard. Two 3.5-inch and two 2.5-inch internal bays remain free for additional storage expansion. Rear I/O includes USB4 Type-C, multiple USB 3.2 and USB 2.0 ports, 2.5Gbps LAN and Wi-Fi 7 with Bluetooth 5.4.

Questions about this item

Does the PC ship with keyboard, mouse or monitor, or must I buy them separately?

The system includes the tower, a 1200 W power supply, liquid CPU cooler, Windows 11 Pro licence and all internal components. Keyboard, mouse and monitor are not included.

Should I pick the 192 GB DDR5 option or a smaller capacity for AI training workloads?

The board supports a maximum of 192 GB across four slots and this build already populates that limit, so no smaller option is offered for this configuration.

What does the 5.70 GHz boost clock on the 24-core Ultra 9 285K mean for sustained rendering?

The processor can reach 5.70 GHz on active cores while the 360 mm liquid cooler manages thermals, allowing high frequencies to hold longer during multi-threaded renders.
