Robust and reliable design

The C64 PSU was designed from scratch as a high-quality replacement for the original Commodore power supply. It contains a +5V/2.0A DC switching power module with an anti-ripple filter, along with a true transformer-based 9V/1.1A AC module. The power supply has a sturdy custom-made chassis with an OLED digital display monitoring the output voltage and uptime.

Dual power supply

The C64 FDD dual power supply has two power outputs, one for the C64 system, and one for the floppy drive 1541-II/1571-II/1581 unit. The FDD output has a round DIN4 plug and supplies +5V/1.0A and +12V/0.5A DC voltage. The entire system can be power through this single power supply.

Modern style chassis

The C64 FDD dual power supply has a chassis design called Modern, and resembles a modern power supply with a slick shape of 125 mm x 59 mm x 42 mm (5.0" x 2.3" x 1.6"). It's a lot lighter and more compact than the original C64 power supplies.

OLED digital display

The OLED digital series has a display showing the output voltage of the power supply, the uptime, and the total time of operation (stored in internal non-volatile memory). This allows to quickly monitor the basic state of the power supply. Touching the sensor below the display will toggle the currently displayed screen.

Precision and dedication

The development of our series of Commodore, Amiga, Sinclair, Atari, Coleco, and TI power supplies has been driven by a sense of sentiment for retro-computing, combined with accuracy and dedication in creating electrical equipment to be proud of. It goes without saying, that the electronics has been designed by skilled professionals, thoroughly tested, and improved based on years of feedback from thousands of users. However, we have also put a lot of effort into the visual appearance of our power supplies. We design and manufacture our own enclosures with CNC and injection molding technologies. The LED and OLED panels are carved from PMMA to give a modern appearance to the power supplies. Hundreds of hours of designing and perfecting have been put into these devices, to create not only a safe and robust power supply, but also a satisfying visual improvement to your system.

What else is out there?

The original Commodore power supplies are very hard to get by these days, and often pose a reliability or even safety threat. As for other replacement power supplies, a handful of solutions exist on the market. Yet most of them are DIY-grade, lacking basic quality, electric engineering expertise, and safety features. The vast majority of these power supplies is recognizable by general-purpose plastic enclosures and internal components wired up in a true DIY style. Opening up a few of those power supplies was big motivation for us to design our Commodore C64, C128, Amiga, Atari, ZX Spectrum, Sinclair QL, TI-99/4A, and ColecoVision power supply series.

Safety first

Our C64 PSU is designed to be safe for the user, and safe for the computer. It's protected from over-current and over-voltage, and fused on both the AC and DC sides. Nevertheless, it's mandatory to say that this is a 120/230V AC power device, which should not be opened, tampered with, or used for anything else than powering an unmodified Commodore 64 computer. It's intended for indoor usage only, the maximum rated current should not be exceeded, and proper ventilation should be ensured. For reference, a picture of the opened power supply is shown below.
