Workstation for AI and content creation

This desktop pairs a 24-core Intel Core i9-14900K with 128 GB of DDR5 memory and an Nvidia RTX A400 GPU. The liquid-cooled CPU and 850 W power supply support sustained workloads in rendering, simulation and machine-learning tasks. It ships with Windows 11 Pro installed and is aimed at professionals who need a ready-to-run platform for GPU-accelerated applications.

Storage capacity and headroom

A 2 TB NVMe drive provides fast boot and project-file access with read speeds up to 7450 MB/s and write speeds up to 6900 MB/s. A 10 TB hard drive adds deep archival space for large media libraries or datasets. Four memory slots are populated to 128 GB with a 192 GB ceiling, so memory-intensive sessions have room to grow before a module swap is required.

Bundled connectivity and expandability

The motherboard rear I/O includes 2.5 Gb Ethernet, Wi-Fi 6 and Bluetooth alongside multiple USB 3.2 Gen 2 and Gen 1 ports plus a USB Type-C connection. The GPU offers four Mini DisplayPort outputs for multi-monitor arrays. Internal bays support two additional 3.5-inch or 2.5-inch drives and two more 2.5-inch units, while four M.2 slots remain available for future NVMe expansion.

Questions about this item

Will my existing SATA SSDs and 3.5" hard drives fit inside the case alongside the installed 10TB drive?

The Antec P20 case provides two internal 3.5"/2.5" bays and two additional 2.5" bays, so your current SATA drives can be mounted beside the factory 10TB HDD.

How can I confirm the liquid cooler is running correctly after I power on the workstation?

Check that the 360mm AIO pump reports a stable RPM in BIOS or monitoring software and that CPU temperatures stay near idle levels under the 24-core i9-14900K.

Which display cables are included for the RTX A400's four Mini DisplayPort outputs?

The GPU ships with four MiniDP ports; MiniDP-to-DisplayPort or MiniDP-to-HDMI cables are not supplied and must be purchased separately.
