24-Core Intel Core Ultra 9 285K Workstation

This system pairs a 24-core Intel Core Ultra 9 285K processor with an Nvidia GeForce RTX 5080 16GB graphics card. It ships with 64GB of DDR5 memory and a combined 18TB of storage across an 8TB NVMe array and a 10TB hard drive. The tower chassis uses a 360mm liquid cooler and a 1000W 80 PLUS Gold power supply. It targets professionals running rendering, modelling and AI learning workloads.

PCIe 4.0 NVMe and 2.5Gb Ethernet Limits

The two Samsung 990 PRO SSDs operate over a PCIe 4.0 x4 interface, delivering sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec. Network connectivity tops out at 2.5Gb Ethernet alongside Wi-Fi 6E and Bluetooth 5.3. Rear I/O includes one USB4 Type-C port, one USB 3.2 Gen 2 port and four USB 3.2 Gen 1 ports. The motherboard provides four SATA 6Gb/s ports with RAID 0, 1, 5 and 10 support.

64GB DDR5 With 192GB Ceiling

The board populates two of four DDR5 slots with 64GB total, leaving room to expand to the 192GB maximum supported by the platform. The 8TB NVMe array handles active project files and operating system duties, while the 10TB hard drive with 256MB cache serves bulk storage. Builds that outgrow the current memory capacity can add modules without replacing the existing kit. Storage expansion beyond the installed drives would require using the remaining M.2 connectors or SATA ports.

Questions about this item

Should I pick the 64 GB DDR5 option or upgrade to the 192 GB maximum?

The system ships with 64 GB DDR5 across four slots. If you run large AI models, heavy rendering or virtual machines, the board supports up to 192 GB; otherwise the factory 64 GB is already strong for gaming and creative work.

What does the 5.70 GHz boost clock on the Core Ultra 9 285K actually deliver in daily use?

The 24-core CPU hits 5.70 GHz on light threads for snappy app launches and game logic, while the 360 mm liquid cooler keeps sustained all-core speeds high during long renders or compiles.

How fast are the two 4 TB Samsung 990 PRO drives over the PCIe 4.0 x4 link?

Each drive is rated for 7450 MB/s read and 6900 MB/s write on the motherboard's M.2 slots, so large project files and game assets load at near-peak PCIe 4.0 throughput.
