24-Core i9-14900K Workstation

This Adamant Custom business desktop is built around a 24-core Intel Core i9-14900K processor with 32 threads and a 360 mm liquid cooler. It ships with 128 GB of DDR5 memory, a 4 TB NVMe SSD, a 10 TB hard drive and an Nvidia RTX A400 graphics card. Windows 11 Pro is pre-installed on the mid-tower chassis.

Suits AI-ready professionals.

The specification targets users who need high single-thread frequency up to 6.00 GHz, large memory capacity and fast NVMe throughput for local AI workloads or content creation. The four MiniDP outputs drive multiple displays from one card. Buyers who require a second graphics card or more than four display connections should consider a different platform.

128 GB DDR5 with 192 GB ceiling

The system includes 128 GB of DDR5 across four slots and the motherboard supports a maximum of 192 GB. This ceiling determines whether future memory expansion can meet your workload without replacing modules. Verify your application’s memory ceiling against this limit before ordering.

Questions about this item

Should I choose the 4TB NVMe SSD or the 10TB HDD for my primary workspace?

Use the 4TB NVMe Samsung 990 PRO for the operating system and active project files; its sequential read reaches 7450 MB/s and write 6900 MB/s. Reserve the 10TB HDD with 256MB cache for bulk archives and backups.

What does the i9-14900K's 6.00 GHz boost mean for daily workstation tasks?

The 24-core, 32-thread CPU can hit 6.00 GHz on thermal headroom, so single-threaded CAD or compile bursts finish faster while the 360mm liquid cooler sustains multi-core loads without throttling.

How does the PCIe 4.0 x4 link cap the 4TB NVMe drive in practice?

The Samsung 990 PRO runs on a PCIe 4.0 x4 interface, limiting peak throughput to the quoted 7450 MB/s read and 6900 MB/s write; real-world sustained speeds stay slightly below those ceilings.
