Ryzen 9 9900X3D liquid-cooled workstation

This desktop pairs a twelve-core Ryzen 9 9900X3D running at 4.4 GHz with a 240 mm liquid cooler on an X870 motherboard. It targets professionals who need sustained multi-threaded throughput for rendering, simulation or compilation workloads. The 1200 W gold-rated supply and Windows 11 Pro complete a turnkey platform.

32 GB DDR5 with 192 GB headroom

Four slots hold 32 GB of DDR5 today and accept up to 192 GB when projects outgrow the factory fit. The 1 TB Samsung 990 Pro delivers 7450 MB/s reads and 6900 MB/s writes for active datasets. Internal bays add two 3.5-inch and two 2.5-inch positions for bulk storage expansion.

RTX 5090 32 GB decides the build

The graphics card brings 32 GB of video memory on a PCI Express x16 link, setting the ceiling for model size, texture resolution and GPU compute queues. Buyers who need more VRAM or a second accelerator cannot add either inside this chassis. Connectivity includes USB4 at 40 Gbps, 2.5 Gb Ethernet and Wi-Fi 7.

Questions about this item

Can I add more DDR5 memory to the four slots on the X870 motherboard later?

The board provides four DDR5 slots with a maximum supported capacity of 192GB, so the installed 32GB kit leaves room for expansion up to that limit.

How do I confirm the liquid cooler and RTX 5090 are running correctly after first boot?

Enter the BIOS to verify the CPU temperature under idle load and check that the GPU appears at PCIe x16 with 32GB VRAM in Windows Device Manager.

What accessories come in the box and what must I supply myself?

The system ships fully assembled with Windows 11 Pro, the 240mm AIO cooler, 1200W PSU, Wi-Fi 7 antenna and front-panel USB-C cable; you only need a monitor, keyboard and mouse.
