Supplemental PCIe Power, a new feature that was designed to deliver additional power to demanding GPUs so they can achieve their peak performance via an integrated 8-pin PCIe power connector, is one of the features that can be found on MSI’s first X870(E) series motherboards for AMD Ryzen 9000/8000/7000 Series processors, MSI has announced. The new motherboards, which include the MAG X870 TOMAHAWK WIFI, are scheduled to arrive on September 26.
MSI’s X870(E) series motherboards include:
- MEG X870E GODLIKE
- MPG X870E CARBON WIFI
- MAG X870 TOMAHAWK WIFI
- PRO X870-P WIFI
MSI on PCIe Power:
- “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.”
- “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.”
- “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.”

MSI noted:
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.
