Core Ultra 9 285K Workstation

This desktop ships with a 24-core Intel Core Ultra 9 285K processor, 128GB of DDR5 memory and a 4TB Samsung 990 PRO NVMe drive. It targets creators and engineers who need high multi-thread throughput and fast local storage in a single mid-tower chassis.

Z890 platform limits

The Gigabyte Z890M AORUS motherboard caps total DDR5 capacity at 192GB across four slots and provides three M.2 connectors for additional NVMe drives. Rear I/O includes USB4 Type-C, 2.5Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4, while front-panel ports stop at USB 3.2 Gen 2x2 Type-C.

Liquid-cooled mid-tower

A 360mm quiet-edition AIO handles the CPU, fed by two 140mm PWM front fans behind a tempered-glass side panel. The Thermaltake 850W 80 PLUS Bronze unit uses a Japanese main capacitor and a 140mm fan, leaving two 3.5-inch and two 2.5-inch bays free for future expansion.

Questions about this item

Should I pick the 128GB DDR5 configuration or the 192GB maximum?

The system ships with 128GB DDR5 installed across four slots. The motherboard supports up to 192GB total, so you would need to replace modules to reach that limit.

What does the 5.70 GHz figure mean for daily workloads?

That is the maximum turbo frequency of the 24-core Intel Core Ultra 9 285K. Sustained speeds depend on the 360mm liquid cooler and the workload; single-thread bursts can hit 5.70 GHz while all-core loads run lower.

How fast is the Samsung 990 PRO 4TB over PCIe 4.0x4?

Sequential reads reach 7450 MB/s and writes reach 6900 MB/s. The Z890 chipset provides three M.2 slots, so this drive uses four lanes of PCIe 4.0 bandwidth.
