I have a power supply that appears to be fine. It beeps on power but unable to power up the motherboard. After trying a different power supply, a second works and it is obviously that this one is at fault.
Is power supply tester able to determine power reliability? It passed two power supply tester and I suspect the fault unit is unable to provide constant and reliably power.
The only thing I noticed is that -12V (~12.4 - 12.5) and +5V (~5.0 - 5.1)fluctuates. A picture is shown here - Power Supply Tester
