Core specification

This desktop is built around a 24-core Intel Core Ultra 9 285K processor that reaches up to 5.70 GHz and provides 36 MB of L3 cache. It targets creators and engineers who need high single-thread speed alongside heavy multi-thread throughput for rendering, modelling and AI learning workloads.

Memory and storage capacity

The system ships with 192 GB of DDR5 memory filling all four slots on the Z890 TUF motherboard, matching the board's maximum supported capacity. A 4 TB Samsung 990 PRO NVMe drive delivers up to 7450 MB/s reads and 6900 MB/s writes, while a 10 TB hard drive with 256 MB cache adds bulk storage for project archives.

Sustained-load behaviour

A 360 mm quiet-edition liquid cooler keeps the CPU at stable temperatures during extended render or compute sessions. The Thermaltake Toughpower 1000W 80 PLUS Gold supply with Japanese main capacitors provides steady power, and the case moves air through front and rear 140 mm fans rated at 1500 rpm and 30 dBA each.
