I'm building a PC and trying to figure out the total wattage needed for my setup. I came across the term "USB 3.2 Gen. 2 is used for power transmission" on a PSU website, and I'm unsure what this means for the power calculation. How does this feature affect the overall wattage requirements for my build?

In simple terms, the USB 3.2 Gen. 2 can deliver power through USB ports, depending on your motherboard's capabilities. Some motherboards allow for power delivery (PD) to charge devices like phones, which can range from 15W to 60W or more, particularly with newer standards like USB PD 3.1 that can go up to 240W. While it's cool for features like quick-charging, not every motherboard supports this, so check yours to see if it offers power delivery through the USB ports. It won't significantly impact your overall PSU needs unless you're using high-powered USB-C devices that draw a lot of juice. Just ensure you have a buffer in your PSU wattage for optimal efficiency and stability, especially if you're using powerful components.

Got it! So, I should look at the specifics of my motherboard, like the Gigabyte AMD X870E AORUS MASTER, to determine its supported specs for USB power? Thanks!
