Nintendo Famicom & Super Famicom Power Supply (AU Spec)

The Modern Upgrade for Vintage Japanese & Western Hardware

The Nintendo Famicom and Super Famicom are legendary, but their original 1980s power requirements are often misunderstood. If you are looking at the "10V DC" label on the back of your console, here is why a modern 9V solution from Retro Sales is actually the superior choice for your hardware's longevity.

Our power supply is "Universal," meaning it takes 100V-240V from the wall and outputs a clean, stable 9V DC. This allows you to run Japanese consoles on Australian mains power safely and efficiently.

Why 9V Switchmode is Better Than Original 10V Linear

Back in the 80s, power supplies were "unregulated" linear bricks. An original 10V adapter would often output 14V or more when not under full load, forcing the console to work harder to shed that excess energy as heat.

• Internal Regulation: These consoles use an LM7805 voltage regulator which converts incoming power down to a steady 5V for the internal electronics.
• The Heat Problem: Feeding 10V (or more) into an old regulator creates significant heat. This heat dries out electrolytic capacitors and shortens the life of your console.
• The Retro Sales Solution: Our modern 9V DC Switchmode supply (RSA-0902000) provides a clean, regulated signal. It is far more efficient, runs significantly cooler, and provides the "sweet spot" voltage for the internal regulator to do its job safely.

Compatibility List:

This power supply is specifically designed for the following hardware (Center Negative):

• Nintendo Famicom: Original Red & White (HVC-001)
• AV Famicom: New Famicom (HVC-101)
• Nintendo Super Famicom: (SHVC-001)
• Super Famicom Jr: (SHVC-101)
• Famicom Disk System: (HVC-022)
• NES Top-Loader: US Model (NES-101)
• NES USA Front Loader: (NES-001)
• NES PAL Australian: (NESE-001)

⚠️ Important: The "RF Challenge" for Original Famicom Owners

If you own the Original Red & White Famicom (HVC-001), please note: it only outputs a Japanese RF signal. Because Japanese and Australian TV frequencies differ, you cannot simply tune this into a standard Australian TV.

The Solution: We offer a professional Famicom AV Composite Video Upgrade Service. We modify your console to output standard Yellow/White RCA signals, allowing it to work perfectly on any Australian TV with a crystal-clear picture.

Technical FAQ

• Can a 2000mA supply damage my 850mA console? No. Amperage is drawn by the console, not "pushed" by the adapter. A 2000mA (2A) supply simply means it has the capacity to provide up to that amount. If your console only needs 850mA, it will only take 850mA.
• What is "Low Duty Cycle" and why does it matter? Because our supply has a high capacity (2.5A burst), running a standard console means the adapter operates at a low duty cycle. It isn't working at its limit, which results in much lower operating temperatures and a significantly longer lifespan for the adapter.
• Will this fix my Famicom's "Jailbars"? Quality power is the first step in reducing interference. Our switchmode supplies are filtered to provide clean DC, which helps minimise video noise compared to failing 80s bricks. However, a new power supply cannot replace aging or worn-out capacitors, which are a typical cause of graphical issues. Wavy lines on your screen are often a sign of poor power supplies or failing capacitors inside the console. Additionally, some "jailbar" problems are factory design issues related to how the composite signal was routed on the motherboard; these cannot be solved without hardware modding. Please contact us with your exact issue for advice.
• Is the polarity correct? Yes, this is Center Negative, which is critical for Japanese Famicom and Sega hardware.
