24-Core Liquid Cooled Workstation

This business desktop combines a 24-core Intel Core i9-14900K processor with a 360 mm liquid cooler and 64 GB of DDR5 memory. It ships with Windows 11 Pro on a 1 TB NVMe SSD plus a 10 TB hard drive for bulk storage. The Nvidia RTX A400 GPU provides four Mini DisplayPort outputs for multi-monitor productivity.

Suited for multi-threaded workloads

The 24 cores and 32 threads handle rendering, simulation and heavy multitasking while the four Mini DisplayPort connectors drive several screens from a single card. Buyers who need more graphics memory or additional display outputs should look at a different graphics configuration. The 850 W Bronze power supply and Z790 motherboard leave headroom for future storage or memory upgrades.

RTX A400 with four Mini DisplayPort outputs

The installed GPU is an Nvidia RTX A400 equipped with 4 GB of video memory and four Mini DisplayPort connectors. This specific output arrangement decides whether the system can drive your required monitor count without adapters or a second card.

Questions about this item

Does the Intel Core i9-14900K need a separate LGA 1700 cooler or is one already fitted?

A 360 mm liquid cooler is pre-installed on the CPU, so no separate cooler is required.

Can I keep my older SATA SSDs and 3.5-inch hard drives when moving to this Z790 TUF motherboard?

Yes, the board provides four SATA 6 Gb/s ports and the case includes two 3.5-inch drive bays for legacy drives.

How do I confirm the RTX A400 is recognised and driving all four Mini DisplayPort outputs?

Open Windows Device Manager and verify the Nvidia RTX A400 appears without errors, then check that each connected monitor shows a signal in Display Settings.
