Core Ultra 9 285K workstation

This 24-core desktop targets professionals running rendering, editing, modelling and AI learning workloads. Windows 11 Pro ships pre-installed on an 8TB NVMe array built from two 4TB Samsung 990 PRO drives. Liquid cooling keeps the 3.7GHz processor stable under sustained load.

Build integration and expandability

The Z890M AORUS motherboard provides four DDR5 slots populated with 64GB and supporting up to 192GB total. Front-panel I/O includes USB 3.2 Gen 2x2 Type-C, two USB 3.0 ports and audio. Rear I/O adds USB4 Type-C, multiple USB 3.2 and 2.0 ports, 2.5Gbps LAN and Wi-Fi 7 with Bluetooth5.4. Internal bays accept two 3.5-inch and two 2.5-inch drives for extra storage.

Upgrade context

Buyers moving from systems limited to 32GB memory or single-GPU configurations gain 64GB DDR5 and an RTX 5090 with 32GB VRAM. The 1200W 80 PLUS Gold supply covers the current GPU and CPU headroom. The platform suits users who need PCIe 4.0 storage speed and Wi-Fi 7 connectivity today; builders who require more than 192GB RAM or additional full-length cards should verify chassis clearance.

Questions about this item

How does the 24-core Core Ultra 9 285K handle heat during sustained all-core loads?

The 360 mm quiet-edition liquid cooler is designed to keep the 24-core CPU at stable temperatures while the 1200 W 80 PLUS Gold PSU supplies clean power under continuous load.

What noise level can I expect from the cooling system when the RTX 5090 and CPU run all day?

The 360 mm AIO uses a low-noise 140 mm fan and the PSU has its own ultra-quiet 140 mm fan, so acoustic output stays low even during extended rendering or AI sessions.

Which display cables must I already own to connect a monitor to the RTX 5090?

The RTX 5090 provides standard DisplayPort and HDMI outputs, so have the matching cable for your monitor's input ready before the system arrives.
