Built for 24-core rendering and AI workloads

This desktop pairs a 24-core Intel Core Ultra 9 285K with 128GB of DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. It targets creators and engineers who need sustained multi-threaded performance for modelling, editing and AI learning tasks. The system ships with Windows 11 Pro installed and includes a 4TB NVMe SSD plus a 10TB hard drive for high-capacity storage.

360mm liquid cooler keeps the 24-core CPU quiet

A 360mm Quiet Edition AIO handles the Ultra 9 285K under load while front-mounted 140mm PWM fans move air through the tempered-glass mid-tower. The 1200W 80 PLUS Gold power supply delivers stable power with Japanese capacitors and protections for over-voltage, under-voltage, over-power and short-circuit events. Noise stays low even during extended rendering sessions.

Questions about this item

How is the 360 mm liquid cooler mounted inside the mid-tower case?

The 360 mm AIO radiator fits in the front of the Design North chassis using the two included 140 mm PWM fans, with tubing routed to the LGA 1851 cold plate on the Intel Core Ultra 9 285K.

What maintenance or replacement will the 1200 W 80 PLUS Gold PSU need later?

The PSU uses a high-quality Japanese main capacitor and an ultra-quiet 140 mm fan; under normal loads the fan bearings are the only part that may eventually require replacement.

Which limit appears first when the RTX 5090 32 GB runs sustained heavy workloads?

The GPU's 32 GB VRAM capacity is reached before the 1200 W PSU or the CPU liquid cooler hit their thermal or power ceilings.
