What is Supplemental PCIe Power?
Think of it as an extra battery pack for your motherboard. The system’s 12V power on the 24pin 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.

Breakdown of Key Power Management Features:
Let’s take the MAG X870 TOMAHAWK WIFI motherboard as an example of how MSI is pushing the boundaries of performance for demanding users. Imagine stacking it with the powerful AMD Ryzen™ 9950X processor alongside the cutting-edge GeForce RTX™ 4090 SUPRIM X 24G GPU. At maximum load, these components demand a lot of power. Usually, the motherboard’s 24-pin 12V power connector can only supply a maximum of 168W. While this might be enough for basic operations, it falls short when trying to drive everything to its peak—especially with fans, RGB lighting, and a beastly GPU like the 4090 connected.

That’s where MSI’s 8-pin Supplemental PCIe Power Connector steps in. On the MAG X870 TOMAHAWK WIFI, this additional connector provides up to 252W of extra power, ensuring everything have enough power to run at their full potential. The 24-pin and 8-pin connectors deliver a combine total of 420W, giving the entire system plenty of power headroom to operate smoothly, even under the most demanding conditions.

What does this mean for users? The Supplemental PCIe Power ensures MSI X870(E) motherboards have the stable, consistent power needed to handle high-end GPU performance and maximized system cooling simultaneously. Whether pushing a 4090 GPU to its limits or adding a second GPU for AI complex computation tasks, these motherboards are fully equipped to handle the next generation of power-hungry components, delivering performance and stability.

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 a robust support of all models across MEG, MPG and MAG, ensuring that power distribution is handled efficiently across the motherboard and connected peripherals.
