ATX power supply hack | SG6105DZ | Part-1

Hack ATX power supply based on SG6105DZ IC . SG6105DZ IC have inbuilt voltage protection ( over voltage and under voltage ) and current protection( short circuit ) . So in this video we have hacked this voltage protection using resistor to divide the voltage (voltage divider ) on all three voltage sense pins which is : 2nd pin for 3.3v 3rd pin for 5v 7th pin for 12v And to vary the voltage , we have used potentiometer on 17th pin with the ground . Make sure to remove the resistor which is connected to pin 17 with the ground , otherwise this hack will not work. In the next part we will hack the over current protection (short circuit protection). Note : Be careful while working with smps ,high volt supply . #atx #sg6105dz #electronics #circuit
