Liquid-Cooled Workstation Desktop

This pre-built desktop pairs a twelve-core Ryzen 9 9900X3D processor with an Nvidia RTX 5090 graphics card. It ships with 32GB of DDR5 memory and a 1TB NVMe solid-state drive. The system targets creators and engineers who need high single-thread speed and large video-memory capacity in a ready-to-run Windows 11 Pro machine.

Factory-Installed Cooler and Power Supply

A 240mm liquid cooler keeps the CPU at stable temperatures under sustained multi-core loads. The Thermaltake 1200W Gold-rated power supply delivers overhead for the graphics card and future component upgrades. Both parts are assembled inside a Corsair 4000D chassis with tempered-glass side panels.

PCIe 4.0 Storage and Connectivity Limits

The Samsung 990 PRO drive operates on a PCIe 4.0 x4 link, capping sequential throughput at the rated 7450 MB/s read and 6900 MB/s write. The motherboard provides four M.2 slots, but only the primary slot runs at full x4 bandwidth from the CPU. Rear I/O includes two USB4 ports at 40Gbps and Intel 2.5Gb Ethernet alongside Wi-Fi 7 wireless.
