In a medium mixing bowl, soften the cream cheese by smoothing it out with a spatula.
Add the sour cream, garlic powder, onion powder, ⅔ of the diced jalapeños, half of the chopped bacon, and about ⅔ of the shredded cheddar cheese to the bowl.
Gently fold the ingredients together until they are well combined.
Lay out a piece of plastic wrap on a flat surface. Transfer the cheese mixture onto the plastic wrap and shape it into a ball.
Wrap the cheese ball tightly with the plastic wrap and refrigerate for at least 4 hours, or overnight for best results.
Place the remaining diced jalapeños, chopped bacon, shredded cheddar cheese, green onions, and pecans in a covered container and refrigerate until ready to use.
Just before serving, mix the reserved jalapeños, bacon, cheddar cheese, green onions, and pecans on a plate.
Unwrap the chilled cheese ball and roll it in the mixture on the plate, ensuring the entire surface is coated evenly.
Serve the cheese ball with your favorite crackers and enjoy!
