12-Core Workstation for Modelling and AI

This desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card. It ships with 128GB of DDR5 memory and a 1TB NVMe SSD alongside a 10TB hard drive. The system targets professionals who need local compute for rendering, simulation and AI learning workloads.

Sustained Load with Liquid Cooling

A 240mm quiet-edition liquid cooler handles the CPU while the case supplies two 140mm front fans for airflow. The 1200W 80 PLUS Gold power supply includes over-voltage, under-voltage, over-power and short-circuit protection. This thermal and power envelope keeps clocks stable during extended modelling or training sessions.

Connectivity and Expandability

The X870 motherboard rear panel provides two USB4 40Gbps Type-C ports, three 10Gbps ports, four 5Gbps ports and one USB 2.0 port. Internal headers add a 20Gbps connector, a 5Gbps header and two USB 2.0 headers. Four M.2 slots and two SATA 6Gbps ports remain open for additional NVMe or SATA storage.

Questions about this item

How loud and hot does the 240mm liquid cooler keep the Ryzen 9 9900X3D during all-day workloads?

The 240mm Quiet Edition AIO is designed for low-noise operation while handling the 12-core processor; the case adds two front 140mm PWM fans and a 140mm PSU fan to move heat out of the 447 x 215 x 469 mm chassis.

Which display cables and monitor inputs do I need to use the RTX 5090 32GB straight away?

The graphics card uses a PCI Express x16 slot internally; you will need a monitor with a compatible modern display input such as DisplayPort or HDMI and the matching cable, which are not included with the system.

Can I keep my existing SATA SSDs or hard drives and install them inside this PC?

Yes, the motherboard provides four SATA 6Gb/s ports and the case includes two internal 3.5-inch and two 2.5-inch bays, so current SATA drives can be added alongside the 1TB NVMe and 10TB HDD already fitted.
