You will likely have to pay tariffs if you declare more than $800 worth of goods at customs, as you are required to by law. You declare them based on what you spent to purchase them, not what equivalent goods would cost in the US. Of course, you might also be the kind of person who bought their ps5 in the United States and then took it with them on vacation to do some light gaming in the hotel and is just bringing it back with them at the end of their trip; I couldn’t possibly say.
