After several weeks of leaks and teasers of MSI’s upcoming X870 motherboards, the company officially announced its next-generation AM5 motherboards, which are compliant with the ATX 3.1 standard. MSI also highlighted the “Supplemental PCIe Power” feature, which appears to be a new power connector that delivers extra power to the motherboard.
The standard 24-pin motherboard connector delivers power to everything, such as graphics cards, cooling fans, and RGB lighting. However, the connector is only rated for 168W. Graphics cards require more power, and some consumers use a multi-GPU setup for AI workloads. For example, Nvidia’s next-generation GeForce RTX 50-series (Blackwell) graphics cards are rumored to require at least 500W of power.
