In a kettle, combine chicken, broth, water and chili powder. Bring to a boil.
Reduce heat, cover and simmer for 5 minutes.
Add corn and return to a boil. Reduce heat. Simmer uncovered for 5 minutes or until chicken is no longer pink and corn is tender.
Add salsa and heat thoroughly.
Serve with cheese, corn chips and sour cream.
Notes
Using Cooked Chicken: You can substitute 1 ½ c. cooked chicken and just throw everything but the cheese, corn chips and sour cream into the kettle and serve once it is heated through.
