Product Description
The power supply tester is a powerful voltage tester for PC power supply ATX. BTX and ITX are compatible, and the power supply can be tested. LCD displays the voltage status.
Suitable for ambitious hobby users, as well as specialized trade quick checks.
Plug the power plug 24 PIN and P4, P6 or P8 into the corresponding jacks of the power supply test kit.
When the power is turned on, you will hear a "DuDu" sound, if there is no flashing, the power supply output voltage is normal.
If a certain voltage signal is not detected, or the detected voltage value exceeds the normal value, a "DuDu" long buzzer will be issued; if the corresponding voltage value or PG flashes, the power supply is faulty.
