24-Core Intel Core i9-14900K Workstation
This business desktop pairs a 24-core Intel Core i9-14900K processor with 128GB of DDR5 memory and an Nvidia RTX A4000 graphics card. It targets engineers and designers running SolidWorks, CAD, CAM or CAE workloads that demand high single-thread frequency and professional GPU drivers. The system ships with Windows 11 Pro installed and a 360mm liquid cooler for sustained thermal performance.
PCIe 4.0 NVMe and SATA 6Gb/s storage limits
The 4TB Samsung 990 PRO operates over a PCIe 4.0 x4 link, delivering sequential reads up to 7450 MB/s and writes up to 6900 MB/s. Additional capacity comes from a 10TB hard drive connected via SATA 6Gb/s, which caps sustained throughput well below the NVMe drive. Four M.2 connectors and four SATA ports on the Z790 motherboard allow further expansion, though only the primary M.2 slot runs at full PCIe 4.0 speed.
128GB DDR5 with 192GB ceiling
The platform supports a maximum of 192GB of DDR5 across four slots, leaving 64GB of headroom above the factory 128GB configuration. This capacity comfortably handles large assemblies, simulation datasets and multi-application workflows. Workloads that exceed 192GB — such as massive in-memory databases or extreme rendering queues — would require a different architecture.

Questions about this item
Should I pick the 128 GB DDR5 configuration or upgrade to the 192 GB maximum this board supports?
The system ships with 128 GB DDR5 across four slots; the Z790 TUF motherboard can accept up to 192 GB if your workloads need more headroom.
What does the i9-14900K's 6.00 GHz boost clock mean for daily CAD work?
The 24-core, 32-thread CPU can hit 6.00 GHz on light threads for snappy viewport interaction, while the 360 mm liquid cooler keeps sustained multi-core speeds stable.
How fast is the Samsung 990 PRO 4 TB NVMe drive over the PCIe 4.0 x4 link?
Sequential reads reach 7450 MB/s and writes 6900 MB/s, so large assemblies load in seconds rather than minutes.
