20-Core Ultra 7 Workstation

This business desktop targets engineers and creators who need a 20-core Intel Core Ultra 7 265K processor, 32GB DDR5 memory and an Nvidia RTX PRO 4000 Blackwell GPU with 24GB VRAM for CAD modelling and AI workloads. The system ships with Windows 11 Pro 64-bit and is VR ready.

Liquid Cooling Thermals

A 240mm quiet-edition AIO liquid cooler handles the CPU while three 120mm front fans and a 140mm PSU fan move air through the Antec P20 case with bottom, front and top dust filters. The 850W 80 PLUS Bronze power supply includes over-voltage, under-voltage, over-power and short-circuit protection.

Samsung 990 PRO SSD Speed

The bundled 2TB Samsung 990 PRO PCIe 4.0x4 NVMe drive delivers sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec, accelerating project load times compared with a standard SATA SSD. A 10TB HDD with 256MB cache adds bulk storage for archives.

Questions about this item

How do I install the 240 mm liquid cooler on the LGA 1851 socket, and what step is often missed?

Mount the back-plate, apply thermal paste, secure the cold-plate with the four spring screws in a cross pattern, then plug the pump header into the CPU_FAN connector — forgetting that header leaves the pump unpowered.

Which components will need replacement first, and what are the limits?

The 850 W PSU and 240 mm AIO pump are the likeliest wear items; the motherboard supports up to 192 GB DDR5 and four M.2 slots for future SSD upgrades.

What thermal or power limit appears first during a long SolidWorks render on the RTX PRO 4000 Blackwell?

The GPU 24 GB VRAM fills before the 20-core Ultra 7 265K hits its 5.50 GHz boost ceiling, so texture-heavy scenes throttle the graphics card first.
