The AMD Ryzen 7 7700X3D is not explicitly mentioned in the compatibility lists of the MSI MAG B650 TOMAHAWK WIFI. However, the board does support other Ryzen 7000 models, including the Ryzen 7 7800X3D, suggesting that it could potentially support the Ryzen 7 7700X3D as well, provided that the BIOS version is up-to-date. It would be advisable to consult the official MSI website or support to confirm exact compatibility.
