Popping noises can come from capacitors, but any capacitor will normally pop just once. Arcing can cause popping noises if the current his high enough, while low current arcing, such as from car spark plugs, is more likely to make snapping sounds. So I think there's a marginal short or bad connection inside the PSU that needs to be fixed.
