Place cubed potatoes in a large pot. Add salt and enough water to cover. Bring to a boil, then reduce heat and simmer for about 10 minutes, or until fork-tender. Drain well and let cool slightly.
(Optional) While still warm, toss potatoes with a small splash of vinegar for enhanced flavor.
In a small bowl, whisk together mayonnaise, vinegar, mustard, sugar, and garlic powder until smooth.
In a large bowl, combine potatoes, chopped eggs, celery, and onion.
Pour the dressing over the mixture and gently stir until evenly coated.
Season with salt and pepper to taste.
Garnish with paprika.
Cover and refrigerate for at least 1 hour before serving for best flavor.
