Built for CAD and CAE workloads

This business desktop pairs a 24-core Intel Core i9-14900K with an Nvidia RTX A4000 GPU to handle SolidWorks modelling and engineering simulation. One hundred twenty-eight gigabytes of DDR5 memory and a 1 TB NVMe drive keep large assemblies responsive. A 10 TB hard drive adds bulk storage for project archives.

Ready to run out of the box

The tower arrives with Windows 11 Pro installed and a 360 mm liquid cooler mounted on the CPU. Only the GPU may need its power cables checked after transit. No driver installation is required for the RTX A4000, but a BIOS update on the Z790 motherboard could be necessary if new processor microcode has been released.

Verify power and space before ordering

The 850 W power supply uses standard ATX connectors; confirm your mains voltage matches the unit rating. The case measures 477 mm deep by 220 mm wide by 486 mm high, so measure the intended desk or rack space. Four memory slots are populated, leaving no free DIMM sockets for future expansion beyond the 192 GB maximum.

Questions about this item

How do I confirm the Intel Core i9-14900K is hitting its 6.00 GHz boost clock after setup?

Use a monitoring utility such as HWMonitor or Intel XTU to observe the CPU frequency under load; the 24-core processor should reach 6.00 GHz on active cores when thermal headroom allows.

Which drives and cables are included, and what must I add for extra storage?

The system ships with a 1TB Samsung 990 PRO NVMe SSD installed in an M.2 slot and a 10TB 3.5" HDD mounted in a drive bay; the motherboard provides three M.2 connectors and four SATA 6Gb/s ports for additional drives, which are not supplied.

Should I choose the 128GB DDR5 configuration or plan for the 192GB maximum?

The workstation arrives with 128GB DDR5 across four slots; if your SolidWorks assemblies or CAE simulations regularly exceed that capacity, the board supports up to 192GB total, otherwise the factory amount is sufficient.
