The voltage of 20-pin / 24-pin / 4P / 6P / 8P interface is displayed by the 1.8'' LCD Screen
- If the values "+3.3V", "+12V1", "+5V", "-12V", "5VSB", "PG" (except "+12V2") on LCD Screen do not flash, it indicates that the power 20-pin / 24-pin input of this power supply is normal.
- If the values of "+12V2" do not flash, it indicates that the power 4P / 6P / 8P input of this power supply is normal.
The voltage of IDE (HDD) / Floppy / SATA interface is displayed by the 3 lights on the left of the power tester
- When Plug the IDE (HDD) connector, If the lights of "+12V" & "+5V" are on, it indicates that the IDE (HDD) power input is normal.
- When Plug the Floppy connector, If the lights of "+12V" & "+5V" are on, it indicates that the Floppy power input is normal.
- When Plug the SATA connector, If the lights of "+12V", "+3.3V" & "+5V" are on, it indicates that the SATA power input is normal.
If their test voltage is exceeds the normal range, the buzzer will send out a warning sound of "di di" for a long time, and the corresponding voltage or PG value display status is flashing state, it means that the power supply is a fault source.
