Workstation for CAD and Engineering

This business desktop pairs a 24-core Intel Core i9-14900K with an NVIDIA RTX A4000 GPU, 128GB DDR5 memory and 8TB NVMe plus 10TB HDD storage. It ships with Windows 11 Pro and liquid CPU cooling in a tower chassis.

Buyers needing certified professional graphics

Engineers and modellers using SolidWorks, CAD, CAM or CAE workflows gain from the RTX A4000 and high core count. Users who only need office productivity or entry-level 3D work should consider a lower-specification system.

RTX A4000 professional GPU

The installed NVIDIA RTX A4000 provides certified drivers for engineering applications. If your software requires a different GPU class or consumer GeForce features, this configuration will not match that requirement.

Questions about this item

At what clock speed does the i9-14900K hit its thermal ceiling during long renders?

The 24-core i9-14900K boosts to 6.00 GHz with 36 MB L3 cache; the 360 mm quiet-edition liquid cooler is sized to sustain that frequency under continuous multi-threaded load.

How loud and hot does the 850 W Bronze PSU and AIO get after hours of SolidWorks simulation?

The Thermaltake Smart 850 W unit uses a 140 mm low-noise fan and Japanese capacitors, while the 360 mm AIO runs a quiet-edition pump; together they keep chassis temperatures low without audible ramp-up.

Which display cables and monitor inputs do I need to drive the RTX A4000?

The RTX A4000 provides four DisplayPort outputs; connect each monitor via DisplayPort cable — no adapters or extra hardware are required for standard DP panels.
