Quick PSU diagnostics

Power supply failures are among the most common problems among all retro computer systems. Our power supply tester series for Commodore C64, C128, Amiga 500/500+/600/1200, Atari XL/XE, and ZX Spectrum +2A/+2B/+3 was created specifically to address this issue. Diagnosing a PSU failure can prevent expensive repairs or even save your hardware from a total damage. The power supply tester runs an automatic yet thorough test, measuring currents, voltages, and even voltage ripple.

Amiga PSU Tester

Features

ZX Spectrum Power Supply - Modern Chassis Black

How it works

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 or +/-12V DC depending on the model) 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, C128, Amiga PSU Tester - How It Works

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.
