Built for heavy workloads

This business desktop pairs a 24-core Intel Core i9-14900K with 192GB of DDR5 memory and a 4TB NVMe drive. The Nvidia RTX A400 provides four Mini DisplayPort outputs for multi-monitor setups. It suits professionals running virtualisation, large datasets or parallel compute tasks that demand high thread counts and fast storage.

Liquid cooling and 850W supply

A 360mm quiet-edition liquid cooler handles the CPU thermal load while a 140mm PSU fan keeps the 850W 80 PLUS Bronze unit running at low noise. The system draws power through Japanese main capacitors with over-voltage, under-voltage, over-power and short-circuit protection. Wi-Fi 6 and 2.5Gbps Ethernet share the rear I/O without adding audible fan speed.

Windows 11 Pro and expandable bays

The OS arrives pre-installed with no bloatware, leaving the full 192GB memory ceiling and four M.2 slots available for future upgrades. Two internal 3.5-inch and two 2.5-inch bays sit behind the tempered-glass panel alongside the existing 10TB hard drive. Rear and mid-board USB Type-C, Gen 2 and Gen 1 ports plus Bluetooth 5.2 cover current peripheral needs.

Questions about this item

How is the 360mm AIO liquid cooler mounted in the Corsair 4000D case, and what step do builders often miss?

The radiator screws to the top of the case with fans pushing air out; the step people miss is removing the protective film from the cold-plate before seating it on the i9-14900K.

Which component will need replacement first, and what capacity should the new part match?

The 850W 80 PLUS Bronze PSU is the likeliest candidate after several years; any replacement must deliver at least 850W with the same 140mm fan clearance.

What thermal limit appears first when the i9-14900K runs at 6.00 GHz on all 24 cores under sustained load?

The 360mm AIO reaches its heat‑dissipation ceiling, causing the CPU to throttle below its 6.00 GHz turbo to keep temperatures in check.
