20-Core Intel Core Ultra 7 265K Workstation

This business desktop pairs a 20-core Intel Core Ultra 7 265K processor with 64GB of DDR5 memory and an Nvidia RTX PRO 4500 Blackwell graphics card holding 32GB of video memory. The system targets engineers and designers who run SolidWorks CAD modelling workloads and AI-accelerated applications on Windows 11 Pro. A 240mm liquid cooler keeps the CPU at stable clocks during long sessions.

Sustained Load Behaviour

The 240mm liquid cooler and 850W power supply support continuous operation at the CPU’s 5.50 GHz maximum turbo across all 20 cores without thermal throttling. The RTX PRO 4500 Blackwell maintains full 32GB frame-buffer availability for extended rendering or simulation jobs. System memory can be expanded to 192 GB if datasets grow beyond the installed 64GB.

PCIe 4.0 Storage and Connectivity Limits

The Samsung 990 PRO NVMe drive delivers sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec on the platform’s PCIe 4.0 lanes. Four M.2 slots and four SATA 6Gb/s ports provide additional expansion headroom. Rear I/O includes Thunderbolt 4, USB 20Gbps and 10Gbps ports, while Intel 2.5Gb Ethernet and Wi-Fi 7 handle network traffic.

Questions about this item

How loud is the 240mm AIO Quiet Edition liquid cooler when the Core Ultra 7 265K runs at 5.50 GHz all day?

The 240mm Quiet Edition AIO uses a 140mm low-noise fan and liquid cooling to keep the 20-core CPU at 5.50 GHz boost without excessive noise during sustained workloads.

Does the Z890-PLUS TUF motherboard need a separate Wi-Fi 7 antenna or is it built into the rear I/O?

Wi-Fi 7 2x2 and Bluetooth5.4 are integrated on the motherboard; the rear panel includes the antenna connectors so no extra card is required.

Can I keep my existing SATA SSDs and 3.5-inch hard drives when moving to this desktop?

Yes, the motherboard provides four SATA 6Gb/s ports and the Corsair 4000D case has two internal 3.5-inch bays for your current drives.
