24-Core Liquid-Cooled Workstation

This business desktop pairs a 24-core Intel Core i9-14900K processor with 192GB of DDR5 memory and a 360mm liquid cooler in a Corsair 4000D tower. It targets professionals who need sustained multi-threaded performance for rendering, simulation or large dataset analysis. The Z790 TUF motherboard provides 2.5Gbps LAN, Wi-Fi 6 and BLUETOOTH 5.2 connectivity out of the box. Windows 11 Pro 64-bit is pre-installed and ready for immediate deployment.

Verify Power And Display Connections

The system draws power from an 850W 80 PLUS Bronze PSU with a standard IEC inlet, so confirm your mains lead and UPS capacity before ordering. Graphics output relies on four Mini DisplayPort connectors on the RTX A400 card; ensure your monitors have matching inputs or that you have suitable adapters. The motherboard occupies a standard ATX footprint, so the chassis will fit typical rack or floor placements without special brackets. Front-panel I/O includes one USB 3.2 Type-C and two USB 3.2 Gen 1 ports alongside a combo audio jack.

Dual 4TB NVMe Plus 10TB HDD Storage

Two Samsung 990 PRO 4TB drives deliver up to 7450 MB/s read and 6900 MB/s write speeds over PCIe 4.0x4, giving fast scratch space for active projects. A 10TB hard drive with 256MB cache adds high-capacity archival storage on a SATA 6Gb/s link. Four M.2 slots and four SATA ports remain on the board, allowing future expansion without removing the factory drives. The build ships with no bloatware and carries a three-year assembly warranty.

Questions about this item

Does the box include the 8 TB NVMe SSD and 10 TB HDD already installed, or must I buy drives separately?

Both the 8 TB NVMe SSD (two 4 TB Samsung 990 PRO modules) and the 10 TB HDD are pre-installed in the Corsair 4000D chassis, so no additional storage purchases are required.

The system lists 192 GB DDR5 across four slots — is that the maximum the motherboard can take?

Yes, the Z790 TUF board has four DDR5 slots and the 192 GB kit (4 × 48 GB) already reaches the platform’s 192 GB limit, leaving no free slots for further expansion.

With the RTX A400 showing four Mini DisplayPort outputs, can I drive four 4K monitors at once?

The RTX A400 provides four Mini DisplayPort 1.4a connectors and supports up to four simultaneous displays at 4K resolution, making it suitable for multi-monitor workstations.
