Built for rendering and AI workloads

This desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU, 64GB DDR5 memory and a 2TB Samsung 990 PRO NVMe drive. It targets creators and developers who need sustained multi-threaded compute and large video-memory capacity for modelling, editing or AI learning tasks. The Gigabyte Z890 UD motherboard provides Wi-Fi 6E and 2.5Gbps LAN for fast networked storage or cluster work.

Liquid cooling keeps clocks steady under load

A 360mm quiet-edition AIO cooler handles the CPU so frequencies stay near the 5.70 GHz boost during long renders or training runs without thermal throttling. The Thermaltake Toughpower 1200W 80 PLUS Gold PSU delivers stable power to both the 285K and the RTX 5090 through extended sessions. Corsair 4000D airflow and the 140mm PSU fan keep case temperatures controlled when every core and the GPU are saturated.

Pre-assembled with standard ATX parts

The system arrives fully built in a Corsair 4000D tempered-glass case with Windows 11 Pro installed and validated. Internal bays include two 3.5-inch and two 2.5-inch slots, while the board offers four M.2 connectors and four SATA ports for later storage expansion. Builders who need a second GPU should verify dual-slot spacing and power-cable clearance before ordering, as the 5090 occupies significant length and the 1200W unit has fixed cable routing.

Questions about this item

How loud does the 360 mm liquid cooler and 140 mm PSU fan run when the Ultra 9 285K and RTX 5090 are under sustained load?

The CPU uses a 360 mm Quiet Edition AIO while the 1200 W Gold PSU has a 140 mm ultra-quiet fan; together they keep noise low even during long rendering or AI sessions.

What display cables or monitor inputs are needed for the RTX 5090 32 GB to work out of the box?

The RTX 5090 provides standard DisplayPort and HDMI outputs so any monitor with those inputs will connect directly without adapters.

Will my existing SATA SSDs or 3.5-inch hard drives fit inside the Corsair 4000D case alongside the 10 TB drive?

The case has two 3.5-inch and two 2.5-inch internal bays plus four SATA 6 Gb/s ports on the Z890 UD motherboard, leaving room for additional drives.
