Workstation for AI and compute

This business desktop combines a 24-core Intel Core i9-14900K processor with 128GB of DDR5 memory and an Nvidia RTX A400 graphics card. Liquid cooling keeps the CPU stable under sustained loads. The system ships with Windows 11 Pro and includes Wi-Fi 6 and 2.5Gbps Ethernet connectivity.

Suits creators needing multi-display output

Professionals who require four Mini DisplayPort outputs for multi-monitor setups will benefit from the RTX A400 configuration. Buyers who need more than 4GB of GPU memory or who rely on consumer GeForce features should consider a different graphics solution. The mid-tower chassis limits expansion compared with full-tower workstations.

Storage and power ready for heavy workloads

A 4TB NVMe SSD provides fast primary storage while a 10TB hard drive adds high-capacity secondary space. The 850W 80 PLUS Bronze power supply delivers reliable power to all components. Pre-installed Windows 11 Pro eliminates setup time and includes no bloatware.

Questions about this item

Will the four Mini DisplayPort outputs on the RTX A400 drive my existing DisplayPort monitors without adapters?

Yes, the RTX A400 provides four native Mini DisplayPort connectors so each monitor with a standard DisplayPort input can be connected using a Mini DisplayPort-to-DisplayPort cable.

Does the 360 mm liquid cooler leave enough clearance for tall DDR5 modules in the four DIMM slots?

The 360 mm Quiet Edition AIO mounts to the front radiator bracket, keeping the CPU block low-profile and leaving all four DDR5 slots free for high-performance modules.

After assembly, how can I confirm the Samsung 990 PRO NVMe SSD is running at PCIe 4.0 speeds?

Open Task Manager, select the Performance tab, choose the 4 TB drive and verify the link speed reads PCIe 4.0 with sequential reads near 7450 MB/s.
