Warm cream cheese in a heavy bottomed saucepan over medium heat, stirring until melted.
Stir in cheddar and mozzarella cheese, beer, chili powder, garlic and onion powder, and cayenne pepper into cheese until smooth and heated through, stirring frequently for about 10 minutes.
Preheat a deep fryer to 350°F. Cook ravioli for 1½ - 2 minutes until golden brown (internal temperature should reach 160°F.). Serve ravioli with beer cheese dip.
