Sometimes it can indicate something is better made, like something made with lots of plastic vs more metal. In a PSU you need lots of metal for the windings, cores, and power stabilization components. It should have some heft to it.
Unscrupulous manufacturers will sometimes throw chunks of metal into an item (like Beats headphones) that do nothing except make a thing weigh more to prey on the sense that weight means better quality.
People think weight = quality.
