12-Core Ryzen Workstation

This desktop combines a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5080 graphics card. It ships with 64GB of DDR5 memory and 8TB of NVMe storage across two 4TB Samsung 990 PRO drives. The system targets professionals who need high single-thread speed and GPU acceleration for modelling, rendering and AI workloads.

Upgrade From Thread-Capped Systems

Moving from an 8-core or 10-core platform unlocks 24 threads and 128MB of L3 cache for parallel compile, simulation and training tasks. The 16GB GPU frame buffer and PCI Express x16 link remove VRAM bottlenecks in large scenes. The jump is worth it when current render times exceed acceptable limits or when dataset size exceeds 12GB VRAM.

Check Motherboard And Power Headroom

The TUF X870-PLUS board occupies a standard ATX footprint and requires a 24-pin plus dual 8-pin CPU power connection. Verify your chassis can fit a 240mm radiator and a triple-slot graphics card up to the case length limit. The 1000W 80 PLUS Gold unit supplies dual 12V-2x6 connectors for the RTX 5080; confirm your regional mains cable matches the IEC C14 inlet.

Questions about this item

What case clearance and radiator length does the 240 mm liquid cooler need?

The CoolerMaster HAF 500 tower measures 508 mm deep by 203 mm wide by 508 mm high and ships with a 240 mm radiator mounted to the front 200 mm fan positions, so the case already provides the required clearance.

Which motherboard power connectors must be seated for the Ryzen 9 9900X3D and RTX 5080, and which one do builders often miss?

Connect the 24-pin ATX cable, the 8-pin EPS CPU cable near the socket, and the 12VHPWR cable to the graphics card; the EPS cable is the one most frequently left unplugged.

What is the maximum DDR5 capacity the board supports and how many slots remain free after the 64 GB kit?

The TUF X870-PLUS supports up to 192 GB across four slots; the 64 GB kit occupies two slots, leaving two slots available for future upgrades.
