12-Core Ryzen 9 Workstation

This desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 64GB of DDR5 memory and a 1TB NVMe SSD. The configuration targets content creators and engineers who need strong multi-threaded throughput alongside a GeForce RTX 5070 graphics card. Windows 11 Pro is pre-installed on the system drive.

240mm AIO Cooler Installation

The CPU ships with a pre-filled 240mm liquid cooler mounted to the motherboard inside the Corsair 4000D chassis. No user assembly of the loop is required. Builders adding storage should note the board provides four M.2 connectors and two internal 3.5-inch bays for expansion.

Sustained Load Thermal Behaviour

Under continuous workloads the 240mm radiator and 140mm fan dissipate heat from the 12-core CPU while the 850W 80 PLUS Bronze power supply delivers stable current. The liquid loop keeps core temperatures steadier than air cooling during long render or compile sessions.

Questions about this item

How can I confirm the liquid cooler is running correctly after assembly?

The 240 mm Quiet Edition AIO should show pump RPM and coolant temperature in BIOS or monitoring software while the Ryzen 9 9900X3D stays near its 4.4 GHz base clock under load.

Which components are included in the box and what must I purchase separately?

The system ships fully assembled with the Corsair 4000D case, PRIME X870-P motherboard, 64 GB DDR5, 1 TB Samsung 990 PRO SSD, RTX 5070 12 GB GPU, 850 W PSU and Windows 11 Pro; only a monitor, keyboard and mouse are needed.

Which memory capacity should I choose for this workstation build?

The board offers four DDR5 slots with 64 GB installed and supports up to 192 GB, so the current kit suits most workflows and leaves room for future expansion.
