And then sasuke having a total of three. being a transmigrant, Takimg in itachi's eyes( even though I don't consider it as a external power source since it became his own eyes and since it doesn't give him any extra chakra and it's his own chakra being used from what I knew.) third being he being Gifted power by sage of six paths.

He also received the curse mark from Orochimaru, thing that played a big role in him getting MS, and also for shorter periods of time, he did absorb Orochimaru fact that empowered him (and also had a role in him getting MS) and used the tailed beast at VOTE2. And honestly...you can't really say that SM is an outside source( wich is nothing like being a jinchuriki since Naruto would've mastered it anyway) and getting Itachi's eyes is not since not only fixed his sight and power, but made him reach a much differed level of power.
