Core Ultra 9 285K workstation

This system pairs a 24-core Intel Core Ultra 9 285K processor with 192GB DDR5 memory and an Nvidia RTX 5090 32GB graphics card. It runs Windows 11 Pro on dual 4TB Samsung 990 PRO NVMe drives totalling 8TB. A 360mm liquid cooler and 1200W Gold PSU support sustained heavy workloads.

Suited for rendering and AI training

The 24 cores and 192GB DDR5 capacity serve 3D modelling, video editing and local AI inference. Buyers who need more storage bays than the two 3.5-inch and two 2.5-inch internal slots provide should look elsewhere. The fixed 1200W power supply also limits future GPU upgrades beyond the installed card.

192GB DDR5 maximum memory

The Gigabyte Z890 Eagle motherboard supports a maximum of 192GB across four slots, and this build already populates that limit. Any future memory increase would require a different platform. Verify that your dataset size fits within this ceiling before purchasing.

Questions about this item

Should I pick the 192GB DDR5 configuration or would a smaller kit be enough for rendering and AI workloads?

The system ships with 192GB DDR5 across four slots, matching the board's maximum supported capacity, so heavy rendering, modelling and AI learning tasks have the full memory headroom without needing an upgrade.

What does the 5.70 GHz boost clock on the 24-core Intel Core Ultra 9 285K actually deliver inside this liquid-cooled tower?

With the 360 mm quiet-edition AIO the 24-core CPU can sustain its 5.70 GHz max turbo across multiple cores, keeping 3D rendering, video editing and large-model inference running at peak frequency without thermal throttling.

How fast are the Samsung 990 PRO drives over the PCIe 4.0 x4 link in real use?

Each 4 TB drive is rated at 7450 MB/s read and 6900 MB/s write over PCIe 4.0 x4, and the Z890 board provides two such M.2 slots, so the 8 TB RAID array hits those sequential speeds for project loads and cache-heavy workflows.
