20-Core Ultra 7 Workstation

This desktop pairs a 20-core Intel Core Ultra 7 265K processor with 128GB of DDR5 memory and a GeForce RTX 5090 graphics card. A 1TB NVMe SSD and liquid cooling complete the build for professional rendering, modelling and AI workloads. Windows 11 Pro is pre-installed on the Z890 platform.

Suits AI developers not casual gamers

The configuration targets users who need 32GB of GPU memory and 128GB of system memory for large dataset training or complex 3D scenes. Buyers who only require 1080p gaming performance or standard office productivity should look at a system with lower memory capacity and a smaller graphics card.

128GB DDR5 capacity drives the decision

Four memory slots are populated to reach 128GB with a maximum supported limit of 192GB. If your workload fits within 64GB or demands the full 192GB ceiling, a different memory configuration will be more appropriate.

Questions about this item

How do I confirm the liquid CPU cooler is running after I power on the system?

The 240mm Quiet Edition water cooler spins its 140mm fan at low noise; you should hear gentle airflow and see coolant temperature stabilise in the motherboard monitoring utility within the first minute.

Which components are already installed and which must I source myself?

The chassis arrives with the Core Ultra 7 265K, 128GB DDR5, 1TB Samsung 990 PRO NVMe, RTX 5090 32GB, 1000W 80 PLUS Gold PSU, Z890 TUF motherboard, Wi-Fi 7 and Windows 11 Pro pre-installed; only peripherals and extra storage are optional.

Should I choose the 128GB DDR5 configuration or the 192GB maximum supported option?

The system ships with 128GB DDR5 across four slots; the Z890 board supports up to 192GB, so select 128GB now and add matching DDR5 modules later if workloads demand more capacity.
