Built for AI workloads and content creation

This desktop workstation ships with a 24-core Intel Core Ultra 9 285K processor and 128 GB of DDR5 memory. A 360 mm liquid cooler keeps the CPU stable under sustained multi-threaded loads. Integrated graphics provide display output through USB4 and DisplayPort connections. The system targets professionals who need high core counts and large memory capacity without a discrete GPU.

Replaces older workstations limited to eight

The jump to twenty-four cores and 128 GB DDR5 is worth it when render queues, virtual machines or large datasets exceed the memory or thread budget of previous machines. A 2 TB Samsung 990 PRO NVMe drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s. Four M.2 slots and four SATA ports remain available for additional storage expansion.

Networking uses Intel 2.5 Gb Ethernet plus Wi-Fi 7 and Bluetooth 5.4. The 850 W 80 PLUS Bronze power supply supports the configured components; check any planned add-in cards against the remaining capacity.

Questions about this item

Will the 447 mm deep case with its 360 mm radiator fit on my desk?

The case measures 447 mm deep, 215 mm wide and 469 mm high; the 360 mm AIO radiator mounts inside, so allow at least that depth plus cable clearance.

How do I install the 128 GB DDR5 kit into the four slots on the Z890 Eagle motherboard?

Populate all four DDR5 slots with the matched 128 GB kit; the board runs quad-channel, so use the same bank order shown in the manual to avoid a no-post boot.

When should I plan to service the 360 mm liquid cooler and the 850 W PSU?

Check the AIO for pump noise or coolant loss every 12–24 months; the Thermaltake Smart 850 W unit’s 140 mm fan should be dusted annually and the PSU replaced if voltages drift.
