Built for intensive creative workloads

This desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 128GB of DDR5 memory and a 1TB NVMe SSD. The GeForce RTX 5060 Ti graphics card handles rendering and real-time preview tasks. Windows 11 Pro is pre-installed on a platform designed for workstation reliability.

Straightforward component access

The Corsair 4000D case uses a standard ATX layout with a side panel that removes without tools. The 240mm liquid cooler arrives pre-filled and mounted to the CPU. Four memory slots are populated, so future upgrades require replacing modules rather than adding them. Internal drive bays include two 3.5-inch and two 2.5-inch positions for extra storage.

Verify your workspace and peripherals

The system measures 490mm deep, 239mm wide and 486mm high, so confirm desk clearance before ordering. Rear connectivity includes USB4, 2.5Gb Ethernet and Wi-Fi 7 for high-speed networking. The 850W power supply uses a standard ATX pinout; ensure your mains cable matches local plug standards. No optical drive is fitted.

Questions about this item

How can I confirm the 12-core Ryzen 9 9900X3D is running at up to 5.50 GHz after assembly?

Open Task Manager or Ryzen Master and watch the CPU frequency climb to 5.50 GHz under load; the 240 mm liquid cooler keeps thermals in check so the 128 MB L3 cache can sustain boost.

Which components are pre-installed and which must I source myself for this 128 GB DDR5 workstation?

The case, 850 W PSU, X870 motherboard, 12-core CPU, 128 GB DDR5, 1 TB Samsung 990 PRO NVMe, RTX 5060 Ti 8 GB, Windows 11 Pro and Wi-Fi 7 are all fitted; only peripherals and extra storage are optional.

Should I choose the 128 GB DDR5 configuration or the 192 GB maximum supported by the X870 board?

The system ships with 128 GB DDR5 across four slots; if your workloads need more than 128 GB you can add modules later up to the 192 GB limit.
