20-Core Intel Core Ultra 7 Workstation

This business desktop is built around a 20-core Intel Core Ultra 7 265K processor running at 3.9 GHz with up to 5.50 GHz boost. It targets engineers and designers who need certified GPU performance for SolidWorks modelling and AI-accelerated workflows in a ready-to-use Windows 11 Pro system.

128GB DDR5 and Dual-Storage Change Daily Work

The 128GB DDR5 memory kit fills four slots on the Z890 motherboard, leaving room to reach the 192 GB maximum later. A 1TB Samsung 990 PRO NVMe drive handles active projects at up to 7450 MB/s read, while a 10TB HDD with 256MB cache stores archives and bulk datasets without needing external arrays.

Pre-Assembled Liquid Cooling Simplifies Deployment

The 240mm quiet-edition AIO cooler and Thermaltake 850W 80 PLUS Bronze PSU are installed and cable-managed inside the Antec P10 FLUX case. Builders only need to connect peripherals and network; the main risk is forgetting to seat the RTX PRO 4000 Blackwell 24GB card fully in the PCI Express x16 slot after transit vibration.

Questions about this item

When will the 240 mm AIO liquid cooler need its coolant refreshed or the pump replaced?

The 240 mm AIO is a sealed maintenance-free loop; no coolant refresh or pump service is scheduled during normal use.

Which component hits its thermal ceiling first when all 20 cores run at 5.50 GHz for hours?

The CPU package power limit throttles before the 240 mm AIO saturates, capping sustained clocks under heavy all-core loads.

How loud does the 140 mm PSU fan and the case fans get when the system renders overnight?

The Antec P10 FLUX case uses sound-dampening panels and a fan-control button; the 140 mm PSU fan and four 120 mm case fans run at low RPM, keeping idle noise near ambient and load noise a quiet hum.
