Core Ultra 9 285K Workstation

This liquid cooled desktop pairs a 24 core Intel Core Ultra 9 285K with 192GB of DDR5 memory and a 4TB Samsung 990 PRO NVMe drive. It targets creators and engineers who need high thread counts and fast storage for rendering, compilation or large dataset work. The GeForce RTX 5070 adds GPU acceleration for supported pipelines. Buyers who need more than 192GB of RAM or multiple graphics cards should look elsewhere.

360mm AIO and 850W Bronze PSU

A 360mm quiet edition liquid cooler handles the CPU while the Thermaltake Smart 850W 80 PLUS Bronze unit supplies power with over voltage, under voltage, over power and short circuit protection. The case moves air through two front 140mm PWM fans and a 140mm PSU fan. Noise stays low during typical workloads. The 850W rating defines the total power budget for this build.

Z890 Eagle Connectivity and Expansion

The Gigabyte Z890 Eagle motherboard provides rear USB4 Type-C, USB 3.2 Gen 2 and Gen 1 ports plus four USB 2.0 connections. Internal headers add a front USB 3.2 Gen 2x2 Type-C, two USB 3.0 and audio. Four M.2 slots and four SATA 6Gb/s ports with RAID 0, 1, 5, 10 support remain for extra drives. The mid tower case fits two 3.5 inch and two 2.5 inch bays. Builders needing more than four M.2 devices or a different form factor cannot use this chassis.

Questions about this item

How is the 360 mm liquid CPU cooler mounted in this mid-tower case, and what step do builders often miss?

The 360 mm AIO radiator fits at the front of the 447 × 215 × 469 mm chassis with the two 140 mm PWM fans already installed; the step many miss is connecting the pump header to the CPU_FAN connector on the GIGABYTE Z890 EAGLE board so the firmware can control pump speed.

What components will need attention or replacement after extended use?

The 140 mm front case fans and the AIO pump are the only moving parts; expect to clean dust from the radiator fins and replace the fans if bearing noise appears, while the Thermaltake 850 W Bronze PSU capacitors and the Samsung 990 PRO 4 TB SSD have no user-serviceable wear items.

Which limit appears first when the RTX 5070 12 GB and Core Ultra 9 285K run sustained workloads?

The GPU 12 GB VRAM buffer fills before the 192 GB DDR5 system memory or the 4 TB NVMe SSD become bottlenecks, so texture-heavy 4K workloads will hit the graphics memory ceiling first.
