20-Core Workstation for Rendering and AI

This desktop pairs a 20-core Intel Core Ultra 7 265K processor with an Nvidia GeForce RTX 5080 graphics card. The system ships with 128GB of DDR5 memory and a 1TB Samsung 990 PRO NVMe drive alongside a 10TB hard drive. Windows 11 Pro comes pre-installed on a liquid-cooled platform built for heavy compute workloads.

Suited for Multi-App Production Pipelines

Editors, 3D artists and machine-learning developers who keep large asset libraries local will benefit from the combined solid-state and mechanical storage. The four memory slots support up to 192GB total, so the current 128GB can grow. Buyers who need more than two 3.5-inch drive bays or a second graphics card should look at a larger chassis.

Accessories That Extend Connectivity

The Corsair 4000D case provides a front USB 3.2 Type-C port and an audio combo jack for quick peripheral access. The Z890 TUF motherboard adds rear Thunderbolt 4, multiple 10Gbps and 5Gbps USB ports, Intel 2.5Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4. A 1000W 80 PLUS Gold power supply with a 140mm fan delivers stable power to every component.

Questions about this item

Will my current DDR5 modules fit the four slots on this Z890 board?

The motherboard provides four DDR5 slots; 128 GB is installed and the platform supports up to 192 GB total.

Can the 1000 W Gold PSU and 240 mm liquid cooler handle the 20-core Ultra 7 265K alongside my older PCIe 3.0 add-in cards?

The 1000 W 80 PLUS Gold unit and 240 mm AIO are sized for the 20-core CPU; PCIe 3.0 cards will operate normally in the available slots.

How do I confirm the Samsung 990 PRO is running at PCIe 4.0 x4 speeds after first boot?

Check the drive properties in Windows or run a benchmark; sequential reads up to 7450 MB/s and writes up to 6900 MB/s indicate full PCIe 4.0 x4 operation.
