Digital LCD Display PC Power supply Tester ATX Check Measuring 12V 3.3V 8P 6P 4P
Brand New in Original Anti-Static Packaging
Voltage input: 20/24pin (ATX connector)
Voltage detection: +12V, -12V, +5V, -5V, +3.3V, 5V Stand by (SB) 12V power Good.
Put the power supply 24PIN and P4, P6 or P8 (the 3 plugs should insert at least one, otherwise +12V2 does not have voltage display) plug into the corresponding location of the power tester.
Turn on the power supply power, at the same time "drop" sound two times boot sound, each value were not flicker, indicate the power supply output voltage is normal.
If a voltage signal is not detected, or the detected voltage is beyond the normal range, the buzzer will give out a warning for a long time, and the corresponding voltage or PG value will blink. It indicates that the power supply is a fault power
