Check it before it's too late

Power supply failures are among the most common problems among retro Commodore 64/128 systems. A C64 PSU failure can lead to expensive repairs, or even render the entire system useless. This is specifically why we have designed the C64 power supply tester. It runs a thorough test, minimizing the risk of damage due to an ageing factory power supply.

C64 FDD Dual PSU Tester

Voltage, current, ripple

The C64 PSU tester measures the primary +5V DC output voltage and ripple at a constant current of roughly 400mA...500mA. Secondary voltages (9V AC, 12V DC) are measured at a lower current, typically 50...150mA. Measurement results are updated on a digital OLED display in real-time, allowing a live evaluation of the power quality.

C64 FDD Dual PSU Tester

Dual power supply

The C64 FDD Dual PSU tester has an additional DIN4 input for testing an FDD 1541-II/1571-II/1581 in parallel. The screen will cycle through measurement results performed on both power supplies.

C64 FDD Dual PSU Tester

Long-term testing

The power supply tester has an aluminum heat-sink allowing to dissipate excessive power and perform long-term testing. It's designed to work both as a quick diagnostic tool, and for long-term stability tests.
