20-Core Ultra 7 Workstation

This desktop combines a 20-core Intel Core Ultra 7 265K processor with 64GB DDR5 memory and an Nvidia GeForce RTX 5070 graphics card. It targets professionals who need rendering, modelling and AI learning performance alongside gaming capability. Windows 11 Pro is pre-installed.

Liquid-cooled Z890 platform

A 240mm quiet-edition AIO cooler handles the CPU while the Ceres 300 case provides front and rear 140mm fans rated at 1500rpm and 30dBA. The Z890 TUF motherboard adds rear Thunderbolt 4, USB 20Gbps and 10Gbps ports, plus Wi-Fi 7 and Bluetooth5.4 connectivity. Four M.2 slots and four SATA ports remain available for future storage expansion.

Dual 4TB NVMe replaces smaller boot drives

Two Samsung 990 PRO 4TB SSDs deliver up to 7450 MB/s read and 6900 MB/s write, removing the need for a separate high-speed scratch disk. The 750W 80 PLUS Bronze PSU supports the current GPU; builders planning a higher-tier graphics card will need a larger power supply.

Questions about this item

What Thunderbolt 4 bandwidth does the rear port provide and what does that cap in practice?

The rear Thunderbolt 4 Type-C port runs at up to 40 Gbps, limiting external storage or dock throughput to that ceiling regardless of the device.

What motherboard form factor and case clearance does the 240 mm liquid cooler require to fit?

The Z890 ATX board and Ceres 300 mid-tower accept a 240 mm radiator; the case interior measures 475 mm deep by 245 mm wide by 463 mm high.

How is the 64 GB DDR5 kit installed on the four-slot Z890 board, and which slot pair is the common mistake?

Populate the two modules in the primary channel slots (usually DIMM A2 and B2) first; using the secondary pair alone prevents dual-channel operation.
