24-Core Liquid-Cooled Workstation

This business desktop pairs a 24-core Intel Core i9-14900K with a 360 mm liquid cooler and 64 GB of DDR5 memory. An Nvidia RTX A400 provides four Mini DisplayPort outputs for multi-monitor workflows. The system ships with Windows 11 Pro and fits in a Corsair 4000D tower case.

Sustained Load Behaviour

The 360 mm Quiet Edition AIO keeps the CPU near its 6.00 GHz turbo across 24 cores and 32 threads during long render or compile jobs. An 850 W 80 PLUS Bronze PSU with Japanese main capacitors delivers stable power without audible fan ramp. Thermal headroom stays consistent thanks to the 140 mm radiator fan.

Storage and Connectivity Limits

Dual 4 TB Samsung 990 PRO drives on PCIe 4.0 x4 M.2 slots reach 7450 MB/s read and 6900 MB/s write. A 10 TB hard drive adds 256 MB cache for bulk archives. Rear I/O includes 2.5 Gbps Ethernet, Wi-Fi 6 and Bluetooth 5.2, while four SATA ports and four M.2 connectors remain for future expansion.

Questions about this item

How loud and hot does the 360 mm liquid cooler keep the i9-14900K when the workstation runs all day?

The 360 mm Quiet Edition AIO uses a 140 mm low-noise fan and is designed to handle the 24-core CPU under sustained load without excessive noise or heat.

What display cables or adapters must I already own to use the RTX A400's four Mini DisplayPort outputs?

The GPU provides four Mini DisplayPort connectors, so you need monitors with Mini DisplayPort inputs or suitable adapters for standard DisplayPort, HDMI or USB-C displays.

Will the Z790 TUF motherboard's four SATA ports and four M.2 slots let me keep my older 2.5-inch SATA SSDs and mechanical drives?

Yes, the board includes four SATA 6 Gb/s ports and four M.2 connectors, so existing SATA SSDs and hard drives can be installed alongside the new NVMe storage.
