Place the peeled and cubed potatoes into the crock pot. Add chicken broth, garlic powder, ranch seasoning mix, and a pinch of salt and pepper. Stir to combine.
Cover and cook on low for 6-7 hours, or until the potatoes are tender.
Using a potato masher or immersion blender, mash some of the potatoes to your desired consistency.
Stir in the softened cream cheese, cream of chicken soup, shredded cheddar, and sour cream until everything is well combined and creamy.
Add the crumbled bacon and mix well. Allow to cook for an additional 15 minutes until the soup is heated through.
Serve topped with chopped green onions and extra cheddar cheese if desired.
