To watch ATX power supply with AT2005 IC https://youtu.be/T_HoBKYwRSE
i explained practical How to repair computer ATX switch mode power supply SMPS very easy. this PSU is using SDC2921 IC which is PWM and intelligent power supply monitor. i shared my easiest and perfect troubleshooting techniques practical troubleshooting. smps concept and troubleshooting repairing or understanding repair switching mode power supply basics and working principle. how to troubleshoot input electromagnet induction filter, EMI, bridge rectifier and capacitor. we get 330 VDC at main capacitor. after hat the +330 volts are applied to standby power, which is SMPS and makes +5V SB, these stand by voltage are applied to motherboard which pull down the PS ON green wire to zero level, so the ENABLE OR REMOTE ON or CONTROL pin of #smps will go low that will enable pulse width modulation. and also i discussed smps basics. after watching this video you can capable to:- understanding atx power supply basics circuit diagram schematic with complete tutorial working of atx smps if computer power supply does not on, or fan runs and stops, fluctuation, turns on goes off again or fail to start short circuit, or fuse blows burns again and again how to #repair #smps how to #repair #computer #power#supply #atx fuse keeps blowing how to repair switch mode power supply when short circuit at input if SMPS is dead or no ouput if SMPS have fluctuating output or output voltage unregulated if smps have short circuit in output how to eliminate short circuit how to troubleshoot #PWM #SMPS #controller when there is no switching from #MOSFET if SMPS have a whistle sound or excessive noise or excessive heat how to repair mobile charger how to repair computer power supply how to repair laptop charger how to repair inverter of solar system
