Wash, peel (if desired), and dice the russet potatoes into small cubes.
Place diced potatoes, chopped onion, chicken broth, garlic powder, onion powder, salt, and pepper into the slow cooker.
Cover and cook on low for 6-8 hours or on high for 3-4 hours, until potatoes are tender.
Once potatoes are tender, stir in heavy cream, cream cheese, and shredded cheddar cheese until melted and smooth.
Stir in crumbled bacon, reserving some for garnish. Mix well and adjust seasoning to taste.
Ladle soup into bowls, garnish with extra cheese, bacon bits, and chopped chives if desired.
