Diagnose and troubleshoot your desktop PC power supply.
The most comprehensive PSU tester on the market
Check power supply voltages are within the approved limits.
Record the minimum and maximum of voltage and current for each rail.
Measure the exact power drawn from each rail.
Measure the total power drawn from the power supply.
Test for ripple on main voltage rails
Measure and check Power-on Time (T1), Rise Time (T2), PWR_OK delay (T3), and Power-down warning (T6) and check them against the specification.
Measure the minimum slew rate on main voltage rails during power up
Measure the turn-on slope of main voltage rails is positive during power up
Check power sequencing
Five Operating Modes
The PSU Tester can be used inline with a connected Power Supply and full Load.
A PC an 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.
Multiple Units can be used simultaneously to test systems with up to 3 GPUS or 2 CPUs. These can be monitored from one instance of the software.
Why test your PSU?
A failing power supply can often be at the root of problems you might not expect, like random lockups, spontaneous reboots, and even some serious error messages
The PassMark PSU Tester is designed to quickly and comprehensively test a PC power supply.
Includes monitoring software for Windows
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.
Most comprehensive PSU Tester on the market
PassMark's Inline PSU Tester is the most extensive and complete diagnostic utility for PC ATX Power Supply Units on the market. Here's how it compares to other PSU testers.
