24-Core Liquid-Cooled Workstation

This desktop pairs a 24-core Intel Core Ultra 9 285K processor with 32GB of DDR5 memory and a 2TB NVMe SSD. A GeForce RTX 5080 graphics card with 16GB of video memory handles rendering and gaming workloads. The system ships with Windows 11 Pro installed and includes Wi-Fi 6E and Bluetooth5.3 connectivity.

360mm AIO Sustained Thermal Performance

A 360mm quiet-edition liquid cooler keeps the CPU near its 5.70 GHz boost clock during extended compile or render sessions. The Thermaltake Toughpower 1000W 80 PLUS Gold power supply delivers stable output with Japanese main capacitors and a 140mm low-noise fan. The Corsair 4000D chassis provides direct airflow paths for the radiator and GPU.

Upgrade From Air-Cooled Mid-Range Builds

Builders moving from an air-cooled platform with a smaller power supply gain headroom for overclocking and longer boost duration. The four M.2 slots and four SATA ports on the Z890 UD motherboard allow storage expansion beyond the included Samsung 990 PRO drive. Users needing more than 32GB of memory can populate the remaining two DDR5 slots up to 192GB total.

Questions about this item

How loud is the 360 mm liquid cooler and 140 mm PSU fan when the system runs all day?

The 360 mm Quiet Edition AIO and the Thermaltake 1000W PSU with its 140 mm ultra-quiet fan are both designed for low noise under sustained load.

What must I already own to start using this desktop?

You need a display with HDMI or DisplayPort input, plus a keyboard and mouse; the PC ships with Windows 11 Pro installed and ready to boot.

Will my existing SATA drives and USB 2.0 peripherals work with the Z890 motherboard?

Yes — the board provides four SATA 6 Gb/s ports and four rear USB 2.0 ports, so older drives and devices connect directly.
