Description:

The OEM Dreamcast power supply is a combined 110v/240v AC to DC converter. This is quite inefficient and noisy, which can manifest in a “fuzzy” video signal. 

Also, plugging in a UK 240v supply to a 110v Japanese Dreamcast can cause damage to the Dreamcast.

You will need your own USB C wall adapter and USB C cable, a 5v or 20v Power Delivery USBC charger such as those from Anker, uGreen and other reputable brands, most 30W charger USBC will work (they have to be able to output 15v/20v)

A screwdriver is the only thing needed to install this power board, no soldering or other technical skills needed. (Screwdriver not included)

What the robot_retro Dreamcast Power Board Offers:

Powered from a 15v or 20v Power Delivery USBC charger (e.g. Ankur, Dell, uGreen, etc.). Most 30W charger USBC will work (they have to be able to output 15v/20v).
Tested to be between 90 and 95% efficient across all loads. 
Low signal noise and heat.
Drop in solution. No soldering, wires or complicated install required.
No flashing LEDS, perfect for clear shells.
Works perfectly with GDEmu.
Works with all Dreamcast models (PAL, Japanese, etc) and removes the risk of accidentally plugging in 240V into a 110V system and causing damage.
Overvoltage, over temperature and fused supply.
3D printed spacer.
