Purpose-built workstation

This liquid-cooled desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU for creators and gamers who need sustained compute and graphics throughput. Thirty-two gigabytes of DDR5 memory and a four-terabyte NVMe SSD provide capacity for large media projects and modern game libraries. The system ships with Windows 11 Pro on a mid-tower chassis.

Graphics memory decides fit

The RTX 5090 ships with 32GB of video memory, the single specification that determines whether the card can hold massive textures, high-resolution frame buffers or large AI models without swapping. Buyers who need more VRAM for 8K workflows or multi-GPU scaling cannot expand this allocation on this platform.

Sustained load behaviour

A 360mm quiet-edition liquid cooler and a 1200W 80 PLUS Gold power supply keep the CPU and GPU at stable clocks during long rendering or training sessions. Case airflow uses four 140mm fans rated at 1500rpm and 30dBA to move heat without audible distraction.

Questions about this item

What does the 24-core Intel Core Ultra 9 285K deliver in actual workloads?

The 24-core CPU reaches 5.70 GHz boost and includes 36 MB L3 cache, giving strong multi-thread throughput for gaming, rendering and AI-ready tasks.

How does the Thunderbolt 4 Type-C port on the Z890 motherboard limit external devices?

The single rear Thunderbolt 4 Type-C runs at 40 Gbps and shares bandwidth with the chipset, so daisy-chained storage or docks will hit that ceiling.

Will the 360 mm AIO and Ceres 300 case clear tall RAM or a second radiator?

The 360 mm Quiet Edition AIO mounts in the roof of the 475 x 245 x 463 mm mid-tower; front 140 mm fans leave standard DDR5 clearance but a second 360 mm radiator will not fit.
