Place the potatoes in a large saucepan. Cover with 2 inches of water.
Bring the water to a boil and continue boiling for 12-15 minutes.
Drain potatoes and pour into a large bowl.
Meanwhile, heat a skillet over medium heat. Add the bacon and cook for 3-4 minutes per side, or until the bacon is brown and crispy. Remove from pan and drain on a paper towel lined plate. Crumble.
Add the scallions, vinegar, mustard, sugar, salt, pepper, garlic powder, bacon, and 2 tablespoons of bacon dressings to the bowl with the potatoes. Toss to combine.
