ASUS Prime TRX40-Pro is expertly engineered to unleash the full potential of AMD's latest high-core-count processors for content creators, designers and professional use. Combining a robust power design, comprehensive cooling solutions, ultrafast PCIe 4.0 connectivity and intelligent tuning options, the high-end desktop motherboard delivers the performance and stability needed to turn every creative vision into reality.
AMD's HEDT platform raises the stakes with the latest AMD 3rd Gen Ryzen™ Threadripper™ processors that boast more cores and higher bandwidth than ever before. Prime TRX40-Pro is ready for the additional processing power that plows through intensive tasks such as 3D rendering and video editing, and the extra bandwidth allows you to add multiple graphics cards and NVMe SSDs to accelerate your productivity.
The new AMD Socket sTRX4 is compatible with 3rd Gen AMD Ryzen Threadripper CPUs with up to 32 cores, up to 64 PCIe 4.0 lanes, and 280-watt thermal design power (TDP). Such specifications require serious power, so Prime TRX40-Pro is equipped with an enhanced power solution that includes 16 power stages to ensure your processor keeps up with your creativity.
ProCool II connectors ensure a snug and reliable connection to the EPS 12V power lines. The second-generation features upgrades of metal amour and solid pins for better heat dissipation, as well as a warning LED-display with a Bioses POST message to indicate improper connections.
Prime TRX40-Pro's VRM is comprised of 16 power stages, delivering the power and efficiency that the latest AMD processors demand.
Superior chokes and durable caps are engineered to resist extreme temperatures and provide better performance.

Fully loaded takes on a new meaning when you have up to 64 PCIe 4.0 lanes stemming from the CPU. These lanes can be split in an x16/x16/x16 configuration spanning the board's trio of PCIe x16 slots, allowing you to load up on GPUs to supercharge your work efficiency – whether you're a CAD professional, 3D artist or other content creation experts.
Each PCI Express slot is bolstered with reinforced walls and a stronger connection to the PCB, which helps it withstand the weight of heavier graphics coolers and protects your investment.
Professional content creation applications require fast solid-state storage, which is why Prime TRX40-Pro is equipped with three PCIe 4.0 M.2 slots that are compatible with the latest NVMe SSDs. All slots support up to 110 mm drives, and they can be configured into bootable RAID arrays for ultrafast data-transfer speeds.
Plenty of USB ports are provided to support high-end rigs loaded with peripherals, including a front-panel Type-C™ connector with faster USB 3.2 Gen 2 connectivity for compatible cases.
The latest Intel® I211-AT Ethernet has the advantage of reducing CPU overhead and offering exceptionally high TCP and UDP throughput for faster, smoother data transfer.

A massive VRM heatsink and high-quality thermal pads enhance heat transfer from the MOSFETs and chokes for better cooling performance. A fan holder is bundled for additional cooling options.
Prime TRX40-Pro features an SoC VRM heatsink, positioned in the pathway of the chipset fan's airflow, to enable the SoC VRM to stay cool during memory overclocking.
PCIe 4.0 provides twice the bandwidth for data flowing through the chipset, which creates more heat than the previous generation. Prime TRX40-Pro features an actively cooled heatsink to prevent throttling during sustained transfers, designed with the screws on top for easy access and maintenance.
* L10 bearing life is a standard metric that specifies the number of hours that 90% of the bearing are expected to continue successfully operating, as a minimum.
Prime TRX40-Pro features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI Bioses.
Each header can dynamically reference three thermal sensors, and via Fan Xpert 4 you can even map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks.
A dedicated header that supplies over 3A for high-performance PWM or DC water pumps, plus a second dedicated header for Aioses.
A dedicated integrated circuit that protects each fan header from overheating and overcurrent.
Each onboard header supports auto-detection of PWM or DC fans.
