MSI is thrilled to introduce a groundbreaking feature on its AMD X870/X870E series motherboards. This innovative is designed with gamers and professionals in mind, and provides the extra power required for AI computing and GPU-intensive applications. The supplemental PCIe Power feature, equipped with an integrated 8-pin PCIe power connector, delivers additional power for GPUs demanding higher wattage, ensuring they can achieve their peak performance. Paired with the ATX 3.1 power standard, which can hold up to a 2.5x power excursion for enhanced reliability and better power delivery, this feature ensures stable, efficient, and sustained performance, even under heavy loads. Whether gaming or tackling complex applications, this supplemental PCIe Power offers unmatched reliability and stability for the most demanding environments.
What is Supplemental PCIe Power?
Think of it as an extra battery pack for your motherboard. The system’s 12V 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 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.
Breakdown of Key Power Management Features
Example: MAG X870 TOMAHAWK paired with AMD Ryzen 9950X & GeForce RTX 4090 SUPRIM X 24G
The MAG X870 TOMAHAWK WIFI motherboard is designed for high-performance users, particularly when paired with an AMD Ryzen 9950X processor and a GeForce RTX 4090 SUPRIM X 24G GPU. These components require significant power, and the motherboard's 24-pin 12V power connector, which supplies up to 168W, may be insufficient for peak performance, especially with additional features like fans, RGB lighting, and a high-end GPU.
The MSI MAG X870 TOMAHAWK WIFI motherboard features an 8-pin Supplemental PCIe Power Connector that adds up to 252W of extra power. Together with the 24-pin connector, they provide a total of 420W, ensuring the system has ample power to run efficiently and handle demanding tasks.
The Supplemental PCIe Power Connector on MSI X870(E) motherboards provides stable and consistent power, allowing them to support high-end GPUs like the RTX 4090 and handle tasks like running multiple GPUs or complex computations. This ensures the motherboards deliver both high performance and stability for demanding, next-generation components.
MSI's ATX 3.1 / 3.0 Ready PCIe5 PSU lineup fully supports the additional 8-pin PCIe power demand, offering stable and efficient power delivery across all connected devices. This includes robust support of all models across MEG, MPG and MAG, ensuring that power distribution is handled efficiently across the motherboard and connected peripherals.
The MSI X870/X870E series motherboards with Supplemental PCIe Power will be available on Sept 26th. To learn more, visit the MSI AMD X870E/X870 Motherboard Lineup Landing Page.
