On the stove, fill a large stockpot with heavily salted water.
Add the potatoes (unpeeled) and bring to a boil over medium heat.
Cook the potatoes until fork-tender, 20 to 25 minutes.
Drain the potatoes and quarter when cool enough to handle and set aside.
In a large bowl, mix together the relish, mustard, garlic powder, smoked paprika, eggs, onion, mayonnaise, and a pinch of salt and pepper.
Add the potatoes and toss until combined.
Garnish with smoked paprika.
Serve immediately or cover and refrigerate until ready to eat.
