Liquid-Cooled Workstation

This liquid-cooled desktop pairs an eight-core Ryzen 7 9800X3D with 64GB DDR5 and an Nvidia RTX A400 to deliver a ready-to-run workstation for professional visualisation and AI-assisted workflows. Windows 11 Pro is pre-installed.

Quiet Build with Front I/O

A 240mm quiet-edition AIO cooler keeps the CPU at low noise while the Corsair 4000D chassis supplies front-panel USB 3.2 Type-C and audio. Rear connectivity adds 2.5G Ethernet, Wi-Fi 7 and multiple high-speed USB lanes including two USB4 ports.

Storage Density Upgrade

Dual 4TB NVMe drives and a 10TB hard drive replace smaller single-drive setups for large datasets and local model weights. The jump is worth it when projects exceed a few terabytes and simultaneous read and write streams are required.

Questions about this item

Does the PCI Express x16 slot on the RTX A400 limit its bandwidth to 4.0 speeds?

The GPU uses a PCI Express x16 interface; the installed Samsung 990 PRO SSDs run at PCIe 4.0x4 with reads up to 7450 MB/sec and writes up to 6900 MB/sec.

What case clearance is needed for the 240 mm liquid cooler and Corsair 4000D chassis?

The system fits in a Corsair 4000D measuring 490 x 239 x 486 mm and includes a 240 mm AIO cooler with a 140 mm fan; internal bays provide two 3.5 inch and two 2.5 inch slots.

How do I enable the 2.5G Ethernet and Wi-Fi 7 on the TUF X870-PLUS motherboard?

Windows 11 Pro 64-bit installs the Intel 2.5Gb Ethernet and Wi-Fi 7 2x2 (802.11be) / Bluetooth v5.4 drivers automatically; connect the RJ-45 cable or select the Wi-Fi network to activate.
