The Dreamcast PicoPSU mod replaces the internal power supply, which originally takes 220-240v (or 110-120v for NTSC consoles) with a modern ATX power supply.
The result is a dramatic decrease in the internal temperature of the Dreamcast. It is paired by a normal 12v (3a or more recommended) external switching power supply. This way you can use your Dreamcast anywhere in the world, regardless what the voltage that is coming out of the mains is!
Furthermore, the kit includes a 3D printed mounting bracket for the PSU socket. These are high quality brackets 3D printed and polished for 8BitMods with SLS technology.
Note: the PicoPSU supplied in this kit is an original Mini-Box PicoPSU and NOT an inferior cloned design that most other sellers supply!
