Power modifications
Various power supply modifications for GameCube that modernize the power delivery system.
Pay attention to the Power Delivery voltage requirements when choosing a USB-C port replacement board. Some designs require 12V PD, which is less common in the USB Power Delivery standard.
Not all USB-C chargers support 12V output. Before purchasing, verify:
- Which voltage your chosen board requires (typically 12V or 15V)
- Whether your USB-C charger supports that specific voltage

Third-party replacement power supplies are not recommended for GameCube. While they may seem like a convenient and affordable option, they often cause more problems than they solve.
Third-party GameCube power supplies are widely available on marketplaces like Amazon and AliExpress. These units are typically manufactured in China and are often marketed as direct replacements for the original Nintendo power supply.
The most common issue is video interference when using analog outputs. Users frequently report:
- Visual glitches and artifacts on screen
- Horizontal lines or noise in the video signal
- Unstable picture quality
- Particularly noticeable when using CRT televisions
- Issues affect analog video and audio output
