Workstation CPU and 128 GB DDR5

This desktop pairs a 24-core Intel Core Ultra 9 285K with 128 GB of DDR5 memory across four slots. The platform supports up to 192 GB total for larger datasets. It targets rendering, modelling and AI learning workloads that benefit from high thread counts and large memory capacity.

Sustained load with 360 mm liquid cooling

A 360 mm quiet-edition AIO cooler handles the CPU under prolonged compute tasks. Front and rear 140 mm case fans run at 1500 rpm and 30 dBA each, moving air through the Ceres 300 mid-tower. The 1000 W 80 PLUS Gold PSU with Japanese main capacitors delivers stable power during extended sessions.

Connectivity and storage layout

The Z890 TUF motherboard provides rear Thunderbolt 4 Type-C, USB 20 Gbps Type-C, three USB 10 Gbps and three USB 5 Gbps ports. Internal headers add another USB 20 Gbps Type-C, USB 5 Gbps and two USB 2.0 connections. Storage uses a 2 TB Samsung 990 PRO PCIe 4.0x4 NVMe drive rated at 7450 MB/s read and 6900 MB/s write, plus a 10 TB HDD with 256 MB cache. Networking includes Intel 2.5 Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4.

Questions about this item

How loud are the 140mm case fans at 1500rpm and 30dBA when the system runs all day?

The front and rear 140mm fans spin at 1500rpm and are rated at 30dBA each, while the 360mm liquid CPU cooler uses a quiet-edition pump and radiator fans designed for low noise under sustained load.

Does the 1000W 80 PLUS Gold PSU include all cables needed for the RTX 5080 16GB and the 2TB Samsung 990 PRO plus 10TB HDD?

Yes, the Thermaltake Toughpower 1000W unit ships with the necessary PCIe power connectors for the graphics card and SATA cables for the hard drive; the M.2 SSD draws power directly from the motherboard.

Will my older SATA 6Gb/s SSDs and USB 5Gbps peripherals work with the Z890 motherboard's four SATA ports and rear USB 5Gbps ports?

The board provides four SATA 6Gb/s ports and three rear USB 5Gbps Type-A ports, so existing SATA drives and USB 5Gbps devices connect natively without adapters.
