There are a number of absolutely amazing new power supply options for the Sega Dreamcast. They all currently rely on you providing the original power switch / assembly (Switch, wire, connector). If yours is broken or missing - finding one on its own can be tough and expensive. 

Gamer Ghosts is here to help! I've sourced the original switch, new stock, found new wire that is the exact specification, a new capacitor, and the matching connector. Fully tested and compatible with new Pico style and original power supplies - all models of Sega Dreamcast consoles.
