Liquid-cooled 24-core Intel Core Ultra 9 desktop with 32GB DDR5, 8TB NVMe storage and GeForce RTX 5090 graphics for 4K gaming and AI workloads
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.
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.
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.

The system ships with 32GB DDR5 across four slots; the Z890 motherboard supports up to 192GB total if your workloads need more capacity later.
The 24-core CPU can reach 5.70 GHz on lightly threaded tasks while the 360mm liquid cooler keeps thermals in check during sustained multi-core loads.
Each M.2 SSD delivers up to 7450 MB/s read and 6900 MB/s write over PCIe 4.0x4, giving the 8TB NVMe array high sequential throughput.
