Workstation for CAD and AI

This business desktop pairs a 20-core Intel Core Ultra 7 265K processor with 64GB of DDR5 memory and an Nvidia RTX PRO 4000 Blackwell graphics card. It targets engineers and designers who run SolidWorks modelling workloads and AI-accelerated applications. The system ships with Windows 11 Pro and includes a 4TB NVMe SSD plus a 10TB hard drive for project storage. Buyers who need more than 192GB of memory or multiple GPU slots should look elsewhere.

Liquid cooling with 240mm radiator

A 240mm quiet-edition AIO cooler handles the CPU thermal load while a 140mm power-supply fan keeps overall noise low. The 850W 80 PLUS Bronze unit delivers power with over-voltage, under-voltage, over-power and short-circuit protection. Liquid cooling and the high-efficiency PSU combine to sustain performance during extended render or simulation sessions. Builders who require a higher-wattage supply or passive cooling will not find those options here.

Customisable configuration and connectivity

The Z890 TUF motherboard provides Thunderbolt 4, USB 20Gbps and 10Gbps ports, Wi-Fi 7, Bluetooth5.4 and 2.5G Ethernet for fast peripheral and network links. Four M.2 slots and four SATA ports allow storage expansion beyond the factory 4TB NVMe and 10TB HDD. The Corsair 4000D case offers two 3.5-inch and two 2.5-inch internal bays for additional drives. Users who need ECC memory support or a different chassis layout cannot select those changes.

Questions about this item

How is the 240 mm liquid cooler mounted on the LGA 1851 socket?

The closed-loop cooler attaches to the motherboard's LGA 1851 retention bracket; the step people miss is tightening the four corner screws in a cross pattern so the cold plate makes even contact with the CPU heat spreader.

Which components will need replacement first during the system's life?

The 140 mm PSU fan and the 240 mm AIO pump are the only moving parts rated for wear; both are user-replaceable without removing the motherboard.

What thermal limit appears first when the 20-core CPU runs at 5.50 GHz continuously?

The 240 mm radiator's heat-dissipation capacity becomes the bottleneck before the CPU hits its own thermal ceiling, so sustained all-core loads will throttle at the cooler first.
