RetroGameCave is the creator of the orginal  TRIO and DUO.



RGC power supplies accept input voltage between 100-240 VAC 60/50Hz and output the proper DC voltage required to run your console.  No Step-Down or Step-Up Transformer is needed.


Classic game consoles are 30+ years old and the power supplies for each of these are aging with them. Leaking dried out capacitors, burned diodes, and failing transformers means gamers need replacement power-supplies. The problem is most everything you see today is designed to be as cheap as possible without any regard to performance or reliability.  These cheap power adapters out of China are often under powered, electrically very noisy, and unreliable. In 2011, RetroGameCave was born with one objective. To develop and provide premium power supplies specifically for classic game-consoles using modern technology that allows them to run cooler with clean power for clean video and audio. We invite you to try our power supplies and see why we have so many repeat customers and why many modders buy power suppliers from RetroGameCave.
