Spray crock pot with non-stick spray and cover the bottom with slightly crushed chips.
Combine soups, rotel, chili powder, and onion in a separate bowl and blend well with a whisk.
Brown ground beef in a skillet, drain fat, and add ranch style beans to it and mix together. (Do not drain the beans). Layer half of the beef mixture over the chips, then half of the soup mixture over the beef, ending with half the cheese over the beef. Repeat these layers once more beginning with chips and ending with cheese.
