Built for 12-core compute and 16 GB GPU memory

This desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5080 graphics card carrying 16 GB of video memory. The system ships with 128 GB of DDR5 RAM and a 2 TB Samsung 990 PRO NVMe drive. A 240 mm liquid cooler and a 1000 W 80 PLUS Gold power supply support sustained workloads in modelling, rendering and AI learning.

Suits professionals who need high thread count

The 12-core CPU and 16 GB GPU memory help with heavy multitasking, large scene rendering and training jobs that benefit from parallel throughput. Buyers who only need casual gaming performance or who require more than 128 GB of system memory should look at other configurations. The four memory slots allow expansion up to 192 GB if future projects demand it.

Verify AM5 motherboard clearance

The TUF X870-PLUS motherboard uses the AM5 socket and fits the supplied mid-tower case measuring 447 x 215 x 469 mm. Check that your workspace accommodates those dimensions and that the 240 mm radiator mounting points align with your planned airflow. The front panel offers one USB 3.2 Gen 2x2 Type-C port, two USB 3.0 ports and audio jacks; the rear I/O includes two USB4 40 Gbps Type-C ports, three 10 Gbps ports, four 5 Gbps ports and one USB 2.0 port.

Questions about this item

Will the motherboard's USB4 ports work with my existing USB 3.2 devices?

Yes, the two USB4 ports on the rear I/O are backward compatible with USB 3.2, USB 3.0 and USB 2.0 devices using the Type-C connector.

Can I add more DDR5 memory later without removing the current 128 GB kit?

The TUF X870-PLUS motherboard has four DIMM slots; the 128 GB kit typically occupies two slots, leaving two free for expansion up to the 192 GB maximum.

How can I verify the Samsung 990 PRO SSD is running at its rated PCIe 4.0 x4 speed?

Open Task Manager or a tool like CrystalDiskMark; sequential reads near 7450 MB/s and writes near 6900 MB/s confirm the drive is operating at full PCIe 4.0 x4 throughput.
