20-Core Intel Core Ultra 7 265K Workstation

This desktop combines a 20-core Intel Core Ultra 7 265K processor with an Nvidia GeForce RTX 5070 graphics card. It ships with 64GB of DDR5 memory and a 1TB Samsung 990 PRO NVMe SSD. The system targets professionals who need strong multi-threaded compute for rendering, modelling and AI learning alongside gaming capability.

64GB DDR5 with 192GB ceiling and 1TB NVMe speed

Four memory slots hold 64GB today and support up to 192GB total, giving headroom for larger datasets. The PCIe 4.0 NVMe drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s, so project loads and asset streaming stay fast. Storage expansion uses the board's four M.2 connectors and two 3.5-inch bays.

Z890 platform upgrade with Thunderbolt 4 and Wi-Fi 7

The Z890 motherboard adds Thunderbolt 4, USB 20Gbps ports and Wi-Fi 7 connectivity over older chipsets. Builders moving from a platform without 2.5Gb Ethernet or Bluetooth 5.4 gain wired and wireless bandwidth for modern peripherals. The 750W 80 PLUS Bronze PSU and 240mm liquid cooler support the installed parts; buyers who want more storage or a second GPU should verify power and clearance before ordering.

Questions about this item

Will my existing DDR5 memory modules work alongside the 64GB already installed?

The board has four DDR5 slots and supports up to 192GB total, so you can add more DDR5 modules to the two free slots.

How can I verify the liquid cooler is running correctly after I power on?

The 240mm AIO uses a 140mm fan; you should hear low fan noise and see CPU temperatures stay low under load in Windows 11 Pro.

What peripherals or cables do I need to buy separately to start using the system?

The box contains the desktop, power cord, and Windows 11 Pro licence; you must supply your own monitor, keyboard, mouse and display cable.
