Built for SolidWorks and heavy CAD

This business desktop pairs a 24-core Intel Core i9-14900K with 128 GB of DDR5 memory and an Nvidia RTX PRO 4000 Blackwell graphics card carrying 24 GB of VRAM. The combination targets engineers and designers who run large assemblies, simulation studies or multi-application workflows that demand sustained single-thread speed and professional driver stability. Windows 11 Pro is pre-installed and ready for domain integration.

Liquid cooling keeps the 24-core CPU quiet

A 360 mm quiet-edition AIO handles the i9-14900K under load while three 120 mm front fans and a 140 mm PSU fan move air through the Antec P20 mid-tower. The Thermaltake Smart 850 W 80 PLUS Bronze unit supplies power with Japanese main capacitors and protections for over-voltage, under-voltage, over-power and short-circuit. Dust filters on bottom, front and top panels reduce internal buildup during long render queues.

Connectivity and expansion for a professional desk

The Gigabyte Z790 AORUS motherboard provides rear I/O with one USB Type-C, two USB 3.2 Gen 2, three USB 3.2 Gen 1 and four USB 2.0 ports, plus front-panel USB 3.2 Gen 2 Type-C and two USB 3.0. Storage uses a 4 TB Samsung 990 PRO PCIe 4.0x4 NVMe drive and a 10 TB HDD with 256 MB cache across four M.2 slots and six SATA 6 Gb/s ports supporting RAID 0, 1, 5, 10. Networking includes Intel 2.5 Gb Ethernet and Wi-Fi 6, while Realtek 7.1 surround audio serves conferencing and media review.

Questions about this item

How do I install the 360 mm liquid cooler on the LGA 1700 socket without bending the mounting brackets?

Fasten the supplied LGA 1700 back-plate, apply paste, then tighten the four spring-loaded screws in a cross pattern until each spring is fully compressed — stopping early leaves uneven contact.

Which components will need replacement first during long-term CAD workloads?

The 850 W Bronze PSU and the 140 mm PSU fan are the only moving parts rated for continuous load; plan to swap the PSU after several years of daily rendering.

What thermal limit appears first when the 24-core CPU sustains 6.00 GHz across all cores?

The 360 mm Quiet Edition AIO reaches its heat-dissipation ceiling before the CPU hits its throttle point, so coolant temperature becomes the governing factor.
