Workstation with 24-Core i9-14900K

This liquid-cooled business desktop pairs an Intel Core i9-14900K running at 3.2 GHz with 128 GB of DDR5 memory and an Nvidia RTX A400 graphics card. Storage combines 8 TB of NVMe SSD space across two Samsung 990 PRO drives with a 10 TB hard drive. Windows 11 Pro is pre-installed.

Suits multi-threaded workloads

The 24 cores and 32 threads handle rendering, simulation and heavy multitasking while the A400 drives up to four displays through its MiniDP outputs. Buyers who need certified drivers for a broader range of ISV applications or who require more than 4 GB of GPU memory should evaluate other configurations.

Deciding spec: 128 GB DDR5 with 192 GB ceiling

Four populated slots deliver 128 GB today and the Z790 TUF motherboard supports a maximum of 192 GB. If your workflow already saturates 128 GB and you cannot add modules later, this platform will not meet the requirement.

Questions about this item

What are the case dimensions and drive-bay layout for the Corsair 4000D chassis?

The tower measures 490 mm deep, 239 mm wide and 486 mm high and provides two internal 3.5-inch bays plus two 2.5-inch bays.

How is the 360 mm liquid cooler mounted and what step is often missed?

The 360 mm AIO radiator installs in the top of the Corsair 4000D case; the step people forget is connecting the pump header and RGB cable to the Z790 TUF motherboard before closing the panel.

When will the 128 GB DDR5 memory or 850 W power supply need replacement?

DDR5 modules and the 80 PLUS Bronze 850 W PSU typically last the system's lifetime; only a failed DIMM or a fan-bearing noise on the PSU would require a swap.
