Q: I have a 2010 vintage 13-inch MacBook Pro that has a 60 watt power adapter.  I also have an older power adapter that is 65 watts.  Is it okat to use the 65 watt with this MacBook Pro?

yes.

"For instance If you have a MacBook (13-inch Late 2009) that normally uses a 60W adapter, you can also use an 85W adapter with that computer. You would not use a 45W adapter with that computer; it would not provide enough power for that MacBook. Using an adapter of higher wattage than the adapter that came with the computer will not cause the computer to charge more quickly or otherwise operate any differently than using the adapter that came with the computer.

Apple has never made a 65W MagSafe power adapter. Are you sure you aren't misreading the info on yours?
