MSI reveals the World’s First ATX 3.1 Ready Motherboards

MSI preps for power-hungry future GPUs with ATX 3.1 AMD X870 and X870E motherboards

MSI has enhanced many of its new AMD X870 and X870E motherboard designs with a new feature that makes them ready for the most powerful and power-hungry next-gen graphics cards. With Supplemental PCIe Power, MSI has created the world’s first ATX 3.1-compliant motherboard. That means that its PCIe slots can handle 2.5x power excursions and have more than enough power to keep even the largest RGB and fan configurations powered.

How was this achieved? MSI added a supplemental 12V power input to their motherboard designs. This added input is an 8-pin PCIe power connector. Typically, motherboards have access to  168W of power through its 24-pin motherboard connector. With their new motherboard designs, MSI’s new motherboards now have access to up to 420 watts of power.

What is Supplemental PCIe Power?
Think of it as an extra battery pack for your motherboard. The system’s 12 V power on the 24-pin power connector from the motherboard basically handles all the PCIe interface, fans and RGB extensions. Still, the supplemental PCIe power ensures everything runs smoothly when your PC is pushed to the limit—like when running very intensive graphical games or maximizing all the fan dissipation for extreme performance.

The extra power means you can game harder, work smarter, and push your PC to its limits without worrying about power shortages or system instability. Whether running extremely intensive games or running complex AI applications, the Supplemental PCIe Power ensures your system stays stable and performs at its best. It’s like knowing your system will keep up no matter what you throw. MSI’s X870(E) series motherboards are ready to support the latest ATX 3.1 and PCIe 5.1 standards, providing the ultimate foundation for future-proof computing. With the addition of the Supplemental PCIe Power, users can confidently run the most demanding games and applications, knowing their system is backed by MSI’s advanced power management technology and is prepared for future advancements in computing power requirements.

This new power design allows MSI’s users to be more confident about using high-power accessories and connecting large numbers of fans and RGB lighting elements to their motherboards. With this extra power budget, users can ensure that their systems remain stable when everything is running at its peak.

MSI has stated that their new X870/X870E motherboards with supplemental PCIe power will be available from September 26th.
