Built for CAD and engineering workloads

This business desktop pairs a 24-core Intel Core i9-14900K with an Nvidia RTX A4000 GPU and 32GB of DDR5 memory. A 1TB NVMe SSD and 10TB HDD provide fast primary storage plus high-capacity secondary space. Windows 11 Pro ships pre-installed on the Z790 TUF platform.

Replaces ageing single-socket workstations

Moving from a system limited to eight or twelve threads and a mid-range professional GPU yields measurable gains in multi-threaded simulation and large assembly handling. The jump is worth it when current render or solve times block project deadlines and memory pressure forces constant swapping.

Verify power and chassis clearance first

The 850W PSU and 360mm liquid cooler demand a case with sufficient radiator mounting space and cable routing depth. Confirm your mains circuit can sustain the load and that the 490mm chassis depth fits the intended location before ordering.

Questions about this item

Will the 490 mm deep Corsair 4000D case fit on my desk shelf?

The tower measures 490 mm deep, 239 mm wide and 486 mm high, so check your shelf clearance against those dimensions.

Which motherboard power connectors must be seated for the i9-14900K and RTX A4000?

Connect the 24-pin ATX cable, the 8-pin EPS cable for the 24-core CPU, and the PCIe power cables required by the RTX A4000; the 850 W PSU includes all necessary leads.

How do I expand the 32 GB DDR5 memory up to the 192 GB maximum?

The Z790 board has four DDR5 slots; add matching DDR5 modules in the empty slots to reach up to 192 GB total capacity.
