The PassMark PSU Tester is designed to quickly and comprehensively test a PC power supply.
The PSU tester can be used inline with a connected Power Supply and full load.
A PC can be connected by USB to monitor the PSU tester in Inline mode.
The PSU tester can be used in standalone mode.
A PC can be connected by USB to monitor the PSU tester in Standalone mode.
Connect the PSU Tester to your PC via the USB connection and you can monitor the PSU statistics, including voltage, current, power, ripple and timing for each voltage rail.
Measurements are clearly displayed with Green background when the value is within acceptable range, and Red background when the value is outside the valid range.
Up to three testers can be monitored from one instance of the software, and all data can be exported to a text file report.
