AMD TRX40 ATX motherboard for Threadripper 3rd Gen

This AMD TRX40 ATX motherboard uses the sTRX4 socket and is built for 3rd Gen Ryzen Threadripper processors. It targets workstation users who need many cores for rendering, simulation or heavy multitasking. The board delivers four-channel DDR4 memory support and three PCIe 4.0 NVMe M.2 slots for fast storage. It suits builders assembling a high-core-count system on a standard ATX form factor.

Ideal for multi-threaded workloads.

This motherboard suits professionals running CPU-heavy tasks that scale across many Threadripper cores. Its four-channel memory architecture and triple M.2 layout benefit video editing, 3D rendering and scientific compute. Builders who need a small-form-factor board or who plan to use mainstream Ryzen desktop processors should look elsewhere because the sTRX4 socket and ATX dimensions are incompatible with those requirements.

Sustained power delivery with active chipset cooling

Under continuous load the 16 Infineon TDA21462 power stages and ProCool II connectors maintain stable voltage to the CPU. VRM, M.2 and SoC heatsinks combine with an active chipset heatsink and hybrid fan headers to dissipate heat during long rendering or compute sessions. The 5-Way Optimization software and UEFI BIOS allow tuning of fan curves and power limits so the platform remains stable over extended workloads.

Questions about this item

Which Threadripper generation is required for the sTRX4 socket on this board?

The sTRX4 socket is built for 3rd Gen AMD Ryzen Threadripper processors.

Will the three PCIe 4.0 M.2 slots share bandwidth with an older PCIe 3.0 graphics card installed in the top x16 slot?

Each M.2 slot runs at PCIe 4.0 independently; a PCIe 3.0 card in the primary x16 slot does not reduce their throughput.

How can I confirm the 16 Infineon TDA21462 power stages are active after assembly?

Enter the UEFI BIOS hardware monitor and verify VRM current and temperature readings under load.
