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.

Questions about this item

How does the 360 mm liquid cooler handle the 24-core Ultra 9 285K under sustained all-core load?

The 360 mm quiet-edition AIO is designed to dissipate the heat from the 24-core processor running at up to 5.70 GHz boost, keeping thermals controlled during extended rendering or AI workloads.

What is the typical noise level from the 1200 W 80 PLUS Gold PSU and 140 mm case fans during all-day operation?

The Thermaltake Toughpower 1200 W Gold unit uses a ultra-quiet 140 mm fan and Japanese capacitors, while the front Aspect 140 mm PWM fans run at low RPM, resulting in minimal audible noise under continuous load.

Which display cables and monitor inputs are needed to use the RTX 5090 32 GB out of the box?

The RTX 5090 requires a monitor with DisplayPort or HDMI inputs and the matching cables; the system ships with Windows 11 Pro installed so the GPU is ready once a compatible display is connected.
