C64 FDD Dual PSU Modern Black US - Replacement C64 + 1541-II Power

In this review the C64 FDD Dual PSU Modern Black US is evaluated as a focused replacement power supply for vintage Commodore systems. It is aimed at owners who want a single, compact unit to power both a Commodore 64 or VIC-20 and a 1541-II series floppy drive; the single biggest reason to buy is the dual-output design that provides stabilized 5V DC and transformer-generated 9V AC together in a small, LED-illuminated chassis that runs cold and protects classic hardware.

Key Features

• Dual outputs: Supplies stabilized 5V DC and 9V AC so a C64 or VIC-20 and a 1541-II series floppy drive can run from one enclosure without adapters.
• Stabilized 5V supply: The filtered 5V/2.0A DC output reduces ripple to protect and extend the life of vintage logic circuits.
• Floppy drive support: Includes stabilized 5V/1.0A and 12V/0.5A DC for floppy drive needs and a transformer 9V/1.1A AC output for correct drive operation.
• Safety and reliability: Fused on AC and DC sides with over-voltage and over-current protection and full isolation to reduce risk to expensive vintage systems.
• Compact, modern chassis: A LED-illuminated enclosure measuring 125 mm x 59 mm x 42 mm keeps the footprint small while indicating power status at a glance.
• US plug and connectors: Built with a US-standard 120V AC plug and the correct Round DIN7 and DIN4 connectors for direct connection to C64 and FDD hardware.

Who It's For

This unit is ideal for collectors and hobbyists who maintain working Commodore 64, VIC-20 and 1541-II/1571-II/1581 drives and want a reliable, single-box replacement that reduces cable clutter and delivers proper voltages. The stabilized 5V supply and transformer AC output make it a practical choice for users who frequently power on vintage rigs for computing, preservation or demo work.

Users who need region-specific plugs other than the US 120V format should look elsewhere, and anyone requiring an exact reproduction of an original brick's form factor or connector wiring beyond the provided DIN7 and DIN4 should verify compatibility before buying.

Pros & Cons

Pros

• Dual power outputs replace separate bricks and simplify setup for C64 plus 1541-II drives.
• Stabilized and filtered 5V rail with transformer 9V AC supports error-free drive operation.
• Built-in protections and fused inputs increase safety for vintage equipment.
• Compact, LED-illuminated chassis runs cold and is easy to tuck behind a desk or shelf.

Cons

• Only supplied with a US-standard 120V AC plug, so buyers outside compatible regions need an adapter or different SKU.
• Weight and small size may feel different from original OEM bricks, which could bother collectors seeking authenticity.

Our Verdict

The C64 FDD Dual PSU Modern Black US is a pragmatic, well-built replacement for anyone who needs a single, safe power source for a Commodore 64 or VIC-20 and a 1541-II series floppy drive. It delivers stabilized voltages, proper AC for drives, compact packaging and protective circuitry, making it good value for preservation-minded users who require reliable operation rather than period-correct cosmetics.

Frequently Asked Questions

Will this power a Commodore 64 and a 1541-II at the same time?
Yes. It provides stabilized 5V DC for the C64 and the appropriate 9V AC plus DC lines required by 1541-II series drives.

Is the unit safe to leave on for long sessions?
Yes. The chassis runs cold, is fused on AC and DC sides, and includes over-voltage and over-current protection for safer long-term use.

Does it work outside the US?
The supply has a US-standard 120V AC plug; users in other regions need a compatible power solution or appropriate mains adapter.
