20-Core Ultra 7 265K Workstation

This desktop pairs a 20-core Intel Core Ultra 7 265K processor with 192GB of DDR5 memory and a 4TB Samsung 990 PRO NVMe drive. A GeForce RTX 5070 12GB graphics card handles visual workloads. Windows 11 Pro runs on a Z890 TUF motherboard inside an Antec P20 tempered-glass case cooled by a 240mm liquid cooler and a 750W 80 PLUS Bronze power supply.

Ideal for AI Development and 3D Rendering

The 192GB memory ceiling and 20-core CPU suit machine-learning training, video editing and complex 3D modelling. Builders who need more than 192GB of RAM, additional GPU power for larger models, or a chassis with greater drive-bay capacity should consider other configurations.

192GB DDR5 Maximum Memory Supported

The motherboard supports a maximum of 192GB of DDR5 across four slots, and this system arrives fully populated. If your workflow demands higher memory capacity, this platform cannot accommodate it.

Questions about this item

Will the 240 mm AIO liquid cooler need coolant replacement or pump service during the life of this PC?

The 240 mm Quiet Edition AIO is a sealed unit; no coolant top-up or pump maintenance is required, though dust should be cleared from the radiator fins periodically.

Which component hits its limit first when the 20-core Ultra 7 265K and RTX 5070 run sustained heavy loads?

The 750 W 80 PLUS Bronze PSU sets the overall power ceiling, so total system draw cannot exceed that rating under continuous load.

How loud and hot does the system get when the 140 mm PSU fan and three 120 mm case fans run all day?

The PSU uses an ultra-quiet 140 mm fan and the front 120 mm fans move air through dust filters, keeping noise low while the liquid cooler handles CPU heat.
