Often people post asking where they can get a quality AC/DC power supply for a retro consoles. I just came across this article on Retro RGB so I thought I'd share it here. In short, there's a brand power adapter called Triad that's found to perform as good as if not better than OEM. Here's the links for the Retro RGB article, his vlog about it, as well as Castlemania Games where you can purchase it.
