Core specification

This business desktop pairs a 20-core Intel Core Ultra 7 265K processor with 32 GB of DDR5 memory and an Nvidia RTX PRO 4500 Blackwell graphics card carrying 32 GB of video memory. The platform targets professional CAD modelling and AI workloads that demand both high thread counts and certified driver stability. Windows 11 Pro 64-bit is pre-installed.

Build integration

The system arrives assembled in an Antec P20 mid-tower case with a 240 mm liquid cooler already mounted on the LGA 1851 socket. A Thermaltake 850 W 80 PLUS Bronze supply powers the components while the Z890-PLUS TUF motherboard provides four M.2 slots and four SATA ports for additional drives. Front-panel I/O includes USB 3.2 Gen 2 Type-C, two USB 3.0 ports and audio jacks.

Sustained operation

Liquid cooling and the case’s three 120 mm front fans with dust filters keep the CPU near its 5.50 GHz boost clock during extended render or simulation runs. The 2 TB Samsung 990 PRO NVMe drive delivers sequential reads up to 7 450 MB/s and writes up to 6 900 MB/s without throttling. The 10 TB hard drive adds 256 MB cache for high-capacity project storage.

Questions about this item

Does the 20-core Intel Core Ultra 7 265K throttle under sustained all-core workloads with the 240 mm liquid cooler?

The 240 mm Quiet Edition AIO cooler is designed for the 20-core CPU; sustained performance depends on case airflow and ambient temperature.

How loud is the 240 mm liquid cooler and the three 120 mm front fans when the system runs all day?

The cooler is a Quiet Edition model and the PSU uses an ultra-quiet 140 mm fan; overall noise stays low under typical workstation loads.

What must I already own to start working because the monitor is not included?

You need a display with HDMI or DisplayPort input, plus a keyboard and mouse; the desktop provides Thunderbolt 4, USB 20 Gbps and 2.5 Gb Ethernet for peripherals.
