14-Core Liquid-Cooled Workstation

This desktop pairs a 14-core Intel Core Ultra 5 245K processor with 128GB DDR5 memory and an Nvidia GeForce RTX 5070 graphics card. It ships with Windows 11 Pro installed on a 1TB Samsung 990 PRO NVMe SSD. The system targets professionals who need strong multi-threaded compute and GPU acceleration in a single pre-built chassis.

Standard ATX Build With AIO Cooler

The motherboard follows the ATX form factor and mounts inside a Corsair 4000D case, so component access is straightforward. A 240mm all-in-one liquid cooler arrives pre-installed on the CPU, removing the need for manual paste application or bracket alignment. Builders should verify that the 12VHPWR connector on the 750W power supply seats fully, as a loose seat can cause instability under load.

DDR5 Platform With PCIe 4.0 Storage

Four DDR5 slots populate the Z890 board, with 128GB installed and a 192GB ceiling for future expansion. The primary SSD operates over a PCIe 4.0 x4 link, capping sequential throughput at the drive's rated 7450 MB/s read and 6900 MB/s write. Rear I/O includes Thunderbolt 4, 20Gbps and 10Gbps USB, 2.5Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4, while internal headers add another 20Gbps Type-C and 5Gbps ports.

Questions about this item

How can I verify the 240mm liquid cooler is running after first boot?

Enter the motherboard BIOS or use the supplied monitoring software to confirm the pump RPM is reported and the CPU temperature sits near idle levels under the 240mm Quiet Edition water cooler.

Which components ship inside the Corsair 4000D case and what must I provide myself?

The system arrives fully assembled with the 14-Core Intel Core Ultra 5 245K, 128GB DDR5, 1TB Samsung 990 PRO SSD, RTX 5070 12GB GPU, 750W 80 PLUS Bronze PSU, Windows 11 Pro, Wi-Fi 7 and Bluetooth5.4; only a display, keyboard and mouse are needed separately.

Should I choose the 128GB DDR5 configuration or upgrade toward the 192GB maximum supported by the Z890 motherboard?

The 128GB DDR5 High Performance Memory fills four slots and suits most gaming and media workloads; select the 192GB maximum only if your professional applications explicitly require capacity beyond 128GB.
