24-core Intel Core Ultra 9 285K workstation

This desktop pairs a 24-core Intel Core Ultra 9 285K processor with 128GB of DDR5 memory and a GeForce RTX 5090 graphics card. It is built for professionals who need heavy multi-threaded compute for rendering, modelling and AI learning workloads. The system ships with Windows 11 Pro and a 2TB NVMe SSD for fast project storage.

360mm liquid cooling and front USB 3.2 Gen 2x2

A 360mm quiet-edition AIO cooler handles the CPU thermal load while the tempered-glass case uses two 140mm PWM fans for airflow. The front panel provides a USB 3.2 Gen 2x2 Type-C port, two USB 3.0 ports and dual audio jacks for everyday peripheral access. Internal bays include two 3.5-inch and two 2.5-inch slots for future storage expansion.

Upgrade from 64GB memory and mid-range GPU systems

Moving from a 64GB DDR5 platform and a lower-tier graphics card to this 128GB configuration with an RTX 5090 32GB GPU unlocks larger scene rendering and faster AI inference. The jump is worth it when project complexity exceeds the VRAM or system memory limits of the previous build.

Questions about this item

What USB standard does the rear USB4 Type-C port use, and what throughput does it cap at?

The rear USB4 Type-C port runs at the USB4 specification and is limited to 40 Gbps in practice.

What are the case dimensions and motherboard form factor needed for this build?

The case measures 447 mm deep, 215 mm wide and 469 mm high and fits a micro-ATX Z890 motherboard.

How is the 360 mm liquid cooler mounted, and which step is often missed?

The 360 mm radiator screws to the front of the case with the supplied fans; the step many miss is connecting the pump header to the CPU_FAN socket on the Z890 board.
