16-core Ryzen 9 9950X3D workstation

The system pairs a 16-core AMD Ryzen 9 9950X3D processor with an Nvidia GeForce RTX 5090 graphics card and 128GB of DDR5 memory. It targets professionals who need heavy multi-threaded compute for modelling, video editing, rendering and AI workloads in a single mid-tower chassis.

Tool-less access and liquid CPU cooling

The Corsair 4000D case opens without tools, exposing a 360 mm AIO liquid cooler mounted on the AM5 socket and four DDR5 slots already populated. The motherboard provides four M.2 connectors, but all are occupied by the factory SSD, so adding further NVMe storage requires removing an existing drive.

4 TB Samsung 990 PRO and 128 GB DDR5 headroom

The PCIe 4.0 x4 SSD delivers up to 7450 MB/s read and 6900 MB/s write, while the memory kit leaves 64 GB of headroom against the 192 GB board limit. The 1200 W 80 PLUS Gold PSU powers the RTX 5090 32 GB and CPU combination, but the four 3.5-inch and two 2.5-inch bays remain empty for future hard-drive expansion.

Questions about this item

How can I confirm the liquid CPU cooler is running correctly after first boot?

The 360 mm AIO quiet-edition cooler should spin its 140 mm fan and show coolant temperature in the motherboard BIOS or monitoring software once Windows 11 Pro loads.

Which components are already installed and which must be purchased separately?

The system ships with the Corsair 4000D case, PRIME X870-P motherboard, Ryzen 9 9950X3D CPU, 128 GB DDR5 RAM, 4 TB Samsung 990 PRO SSD, RTX 5090 32 GB GPU, 1200 W 80 PLUS Gold PSU, liquid cooler, Windows 11 Pro and Wi-Fi 7; only a monitor, keyboard and mouse are needed.

Which memory capacity should I choose if I want the maximum supported by this motherboard?

The board supports up to 192 GB across four slots, so the 128 GB kit leaves two slots free for a future upgrade to the full 192 GB limit.
