Liquid-cooled desktop with 24-core Intel Core Ultra 9 285K, 192GB DDR5, 2TB NVMe SSD, 10TB HDD and RTX 5070 graphics
This desktop pairs a 24-core Intel Core Ultra 9 285K with 192GB of DDR5 memory and a 360mm liquid cooler. The Z890 TUF motherboard provides Thunderbolt 4 and Wi-Fi 7 connectivity. It ships with Windows 11 Pro installed on a 2TB Samsung 990 PRO NVMe drive. A 12GB RTX 5070 handles graphics duties in the Ceres 300 tempered-glass case.
Creators running large datasets, virtual machines or complex timelines will use the full 192GB capacity and fast NVMe storage. The single 12GB RTX 5070 and motherboard layout limit multi-GPU scaling. Buyers who need more graphics memory or a second card should look at a different platform. The 850W PSU supports this configuration only.
The Z890 TUF board offers four slots with a 192GB maximum, matched by the Ultra 9 285K memory controller. All slots are populated at purchase, so no further RAM upgrades are possible. Confirm your applications need this capacity before ordering.

The 24-core CPU reaches up to 5.70 GHz boost clocks while the 360 mm liquid cooler keeps temperatures controlled inside the mid-tower case.
The board runs PCIe 4.0 lanes, so the graphics card and the 2 TB NVMe drive both operate at Gen 4 speeds.
The case measures 475 x 245 x 463 mm and includes bays for one 3.5-inch or two 2.5-inch drives, fitting the 10 TB HDD alongside the AIO.
