24-Core i9-14900K Workstation

This new tower desktop targets professionals who need high multi-threaded throughput for rendering, compilation or simulation workloads. The Intel Core i9-14900K delivers 24 cores and 32 threads with a maximum turbo frequency of 6.00 GHz. Sixty-four gigabytes of DDR5 memory and a 1 TB Samsung 990 PRO NVMe drive provide ample capacity for large datasets. Integrated Intel graphics drive display output via HDMI and DisplayPort.

Liquid Cooling and Z790 Connectivity

A 360 mm quiet-edition AIO cooler handles the CPU thermal load inside a Corsair 4000D tempered-glass chassis. The Z790 PRIME motherboard supplies rear I/O with one USB Type-C, one USB 3.2 Gen 2, two USB 3.2 Gen 1 and four USB 2.0 ports, plus mid-board headers for one USB Type-C, two USB 3.2 Gen 1 and two USB 2.0. Networking includes Intel 2.5Gb Ethernet, Wi-Fi 6 and BLUETOOTH 5.2. Internal expansion offers three M.2 slots and four SATA 6Gb/s connectors alongside two 3.5-inch and two 2.5-inch drive bays.

Thermals, Noise and Power Draw

The 360 mm liquid loop and a 140 mm low-noise chassis fan keep the 24-core processor within operating limits during sustained workloads. A Thermaltake Smart 850W 80 PLUS Bronze unit with Japanese main capacitors delivers power with over-voltage, under-voltage, over-power and short-circuit protection. Windows 11 Pro 64-bit ships pre-installed without bloatware. The system is assembled and tested with a three-year parts and labour warranty.

Questions about this item

What PCIe standard does the Samsung 990 PRO SSD use, and what practical read speed does that cap it at?

The 1TB Samsung 990 PRO runs on a PCIe 4.0 x4 link, giving a rated sequential read speed of up to 7450 MB/sec.

What case clearance is required for the 360 mm liquid cooler, and which chassis is used?

The system ships in a Corsair 4000D tower measuring 490 x 239 x 486 mm; the 360 mm radiator fits in the front or top mounts of this case.

How is the 64 GB DDR5 memory installed, and which mistake should be avoided?

Four DIMM slots are provided on the Z790 PRIME board; populate the two primary slots first for dual-channel operation rather than filling all four at once.
