Core Specification

This system centres on a 24-core Intel Core Ultra 9 285K processor running at 3.7 GHz with a 5.70 GHz boost and 36 MB L3 cache. It ships with 64 GB of DDR5 memory across four slots, expandable to 192 GB, and dual 4 TB Samsung 990 PRO NVMe drives delivering up to 7450 MB/s read and 6900 MB/s write speeds.

Target Builder

The integrated graphics and USB4 plus DisplayPort outputs suit content creators, developers or AI workloads that rely on CPU compute rather than a discrete GPU. Buyers who need dedicated graphics performance for gaming or GPU-accelerated rendering should look at a configuration with a separate video card.

Platform Extras

A 360 mm quiet-edition liquid cooler and an 850 W 80 PLUS Bronze power supply with Japanese main capacitors keep the high-core-count CPU stable under load. The Gigabyte Z890 UD motherboard adds Wi-Fi 6E, Bluetooth 5.3, 2.5 Gb Ethernet, four M.2 slots and extensive USB 3.2 and USB4 rear connectivity inside a Corsair 4000D tempered-glass chassis.

Questions about this item

Does the motherboard have a free DDR5 slot so I can add more memory later?

Yes — the Gigabyte Z890 UD board has four DDR5 slots and only 64 GB is installed, leaving room for up to 192 GB total.

Will my existing SATA SSDs and hard drives work with the four SATA 6 Gb/s ports on this board?

Absolutely — the Z890 UD provides four SATA 6 Gb/s connectors that support RAID 0, 1, 5 and 10 for legacy drives.

How can I confirm the 360 mm liquid cooler is keeping the Core Ultra 9 285K at its 5.70 GHz boost under load?

Watch the CPU temperature in Windows Task Manager or HWMonitor while running a heavy workload; it should stay well below the thermal limit while the clock hits 5.70 GHz.
