What is the New Power Cap in Destiny 2?

If you play through the base game alone, you’ll earn rare, legendary and exotic weapons. While these can be great, they won’t be enough to raise your power to 1570. For that, you’ll need to spend time tackling specific weekly challenges such as seasonal activity rewards, engrams, vendor bounties and more. This stage of the game relies on grinding, and it will probably take a long time. But even once you’ve attained power 1570, there are still more hurdles to grind through.
