MSI's next-generation B650 motherboard featuring the AM5 socket has allegedly been spotted running a next-gen AMD Ryzen 7000 Desktop CPU.

In a picture tweeted by @9550Pro (HXL), we can see an off-screen BIOS display that shows the motherboard with the MAG B650 naming scheme. The MAG series motherboards are designed exclusively by MSI and are the most entry-level in their motherboard family. While we can't say which specific MAG variant this is (Mortar, Bazooka, Tomahawk), we can see that it is based on AMD's B650 chipset which will be part of the next-generation AM5 platform.
