robot_retro Dreamcast Power Board – USB-C Drop-In Replacement

Version 1.1 – Now Includes 5V & 12V Fan Headers

Upgrade your Sega Dreamcast’s power supply with a modern, efficient, and solder-free solution. Designed to work seamlessly with all Dreamcast models and mods—including GDEmu, RetroGEM, and 480p SCART RGB setups.

Key Features

True Drop-In USB-C PSU Replacement

• No soldering, wiring, or modification required.

Universal Compatibility

• Works with all Dreamcast models (PAL, NTSC, Japanese).
• Fully supports GDEmu, RetroGEM, and RetroTINK-powered 480p SCART RGB cables.

High Efficiency & Low Noise

• Delivers between 90–95% efficiency under real-world loads.
• Low heat output and minimal signal noise—reduces video “fuzz” caused by noisy OEM power.

Safe and Reliable

• Built-in overvoltage, over-temperature, and fused protection to safeguard your console.
• Prevents damage caused by plugging 240V into a 110V Dreamcast.

Fan Support (v1.1 Update)

• Includes 5V and 12V fan headers for custom cooling setups.
• Note: The Dreamcast still requires a fan plugged into the OEM fan port for successful boot-up.

No LED Distractions

• Designed without flashing LEDs—ideal for use with clear shell builds.

Multicolour 3D-Printed Spacer Included

• Provides a clean and secure fit in the Dreamcast chassis.

Power Requirements

Powered by a 15V or 20V USB-C Power Delivery charger. Most 30W PD chargers will work.  Recommended models:

• uGreen Nexode Mini 30W
• Nintendo Switch Power Supply
• High-quality filtered chargers from Anker, Dell, uGreen, etc.

Why Replace the OEM Power Supply?

• The stock Dreamcast PSU is an aging AC-to-DC converter that's bulky, noisy, and inefficient
• Common issues include video interference (fuzzy output) and potential voltage mismatch damage—especially when using 240V UK power with 110V Japanese units
