Workstation CPU and Memory

The Intel Core i9-14900K provides 24 cores and 32 threads with a base frequency of 3.2 GHz and a maximum turbo of 6.00 GHz. 192 GB of DDR5 memory fills all four slots and matches the motherboard limit. This configuration targets professionals who need high core counts and large memory capacity for simulation, rendering or data analysis. Buyers who require ECC memory or more than 192 GB should consider a platform that supports registered DIMMs.

Storage Layout and Headroom

A 2 TB Samsung 990 PRO NVMe drive delivers read speeds up to 7450 MB/s and write speeds up to 6900 MB/s for the operating system and active projects. A 10 TB hard drive with 256 MB cache provides bulk capacity for archives and media libraries. The motherboard offers three M.2 connectors and four SATA ports, so additional drives can be added. Users who need all-flash storage or RAID redundancy will need to populate the remaining slots themselves.

GPU Interface and Display Limits

The Nvidia RTX A400 includes 4 GB of video memory and four Mini DisplayPort outputs. It is suited for multi-monitor business setups and light GPU-accelerated workloads. The card occupies a single slot and draws modest power from the 850 W supply. Workloads that require larger frame buffers, multiple full-size DisplayPort or HDMI connectors, or higher compute performance will exceed what this GPU can provide.

Questions about this item

Will the 2TB Samsung 990 PRO NVMe drive work with my existing SATA SSDs on the Z790 PRIME board?

Yes, the motherboard provides four SATA 6Gb/s ports and three M.2 connectors so the NVMe boot drive and any 2.5-inch SATA drives can run together.

How can I verify the RTX A400 is recognised and running at full x4 Mini DisplayPort output after assembly?

Open Device Manager in Windows 11 Pro, confirm the GPU appears without warning icons, then connect up to four displays to the MiniDP ports and check each shows a signal at native resolution.

Which items ship inside the Antec P10 FLUX case and what must I source separately?

The system arrives fully assembled with CPU, 192GB DDR5, 2TB NVMe, 10TB HDD, RTX A400, 360mm liquid cooler, 850W PSU, Wi-Fi 6 and BLUETOOTH 5.2; only a monitor, keyboard and mouse are needed to start.
