The LCD displays various parameters such as output voltage and PG. When each parameter exceeds the normal value, the buzzer will sound a warning sound, and the corresponding value will flash; This power tester only needs to be connected to the ATX connector of the power supply to easily and intuitively know whether the output of each power supply is normal.; Can detect ATX, BTX, ITX, TFX computer power, and can display the voltage and PG value of each group of LCD, quickly detect the performance of computer power.
; It can measure the voltage of each group of the power supply 3.3V / + 5V / + 12V / -12V / SB + 5V / PG. If there is a fault, the buzzer will automatically alarm and the output wire P4 / P6 / P8 / SATA / IDE; External DIE / SATA / P6 / P8 is light display, no LCD display voltage
