24-Core Liquid-Cooled Workstation

This desktop combines a 24-core Intel Core Ultra 9 285K processor with a 360 mm liquid cooler and an Nvidia GeForce RTX 5090 graphics card. It ships with 32 GB of DDR5 memory and 8 TB of NVMe storage across two Samsung 990 PRO drives. The system targets creators and gamers who need high single-thread speed and massive parallel throughput in a single tower.

Z890 Platform Connectivity Limits

The Gigabyte Z890 UD motherboard provides one USB4 Type-C port, one USB 3.2 Gen 2 port and four USB 3.2 Gen 1 ports at the rear, plus a front-panel USB 3.2 Type-C connector. Networking tops out at Intel 2.5 Gb Ethernet and Wi-Fi 6E with Bluetooth 5.3. Four SATA 6 Gb/s ports and four M.2 slots set the ceiling for additional internal drives.

32 GB DDR5 and 8 TB NVMe Headroom

The 32 GB DDR5 kit occupies two of four slots, leaving room to reach the 192 GB maximum supported by the platform. The paired 4 TB NVMe drives deliver up to 7450 MB/s reads and 6900 MB/s writes, covering large project libraries and game installs. Builds that outgrow 8 TB or 32 GB can expand within the case’s four M.2 slots and four DIMM sockets.
