i explained practical How to repair computer ATX switch mode power supply. this PSU had no output on STBY +5V standby missing, short circuit in input section, the fuse burnt out. i replaced the standby section wit a buck converter
i shared my easy and perfect troubleshooting technique to repair computer AT or ATX power supply, i found rectifier diodes, fuse, power transistor, diodes in standby inverter section. 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:-

Hi, I'm trying to repair my 450w ATX, 5vsb was good and noting shorted but it just can't start up, it use WT7527 , TNY277, UC38438 and LM339 IC, all capacitors, transistors, IC, diodes were checked good, WT7527 on PGI and PGO have no power, VCC have 4.5v. but one of the diode SBR20100 if using ohm meter to check is only 300ohm, I wonder will it caused the problem. BTW it's just my hobby to repair non working things. : )

Hello sir, in other video you said standby transformer give 2 power, 5v and 9-12v, then 9-12v use for signal tranformer. Why in this video you only replace with 5v adapter ? So how to give 9-12v for signal transformer to work ? How much power for signal transformer need ? Can it work with 5v ?

Assalamu alaykom brother and thank you very much for the video. It is very beneficial what you do for us. This last week I bought a switch mode power supply for a PC of type: BEBIBOS POWER SUPPLY ATX 12V V2.32 MODEL NO: ATX-P4 500W at first I thought it was on, when I turned it on I noticed that the fan ran for about 30 seconds and stopped. After a 15 minutes stop I turn it on as usual the fan spins a few seconds and stops. I checked the state of some components: the bridge diodes, the capacitors, the zener diodes, the switching diodes, and even the IC, but in vain it's always the same: the fan turns a few seconds and stops. However, I have the 5V of the green wire as well as the 5V of the purple wire(standby voltage) - Question: according to your experience how to repair this power supply? Thanks your brother from Tunisia.

@HaseebElectronics LOL... Why didn't rebuild the traces using copper wire/soldering wick and fix that standby section? Even if transformer is shot, you can easyly open it using a heatgun/hotair or simply throw it into boiling water, and simply rewind it!, eventualny salavage simillar transfromer from other SMPS and just replace it...

How much voltage is the computer power supply green wire
@HaseebElectronics 3 жыл бұрын
green wire is PS ON command basically it is taken from 5 volt standby through a resistor. so in normal condition it is around 5 volt in some models it is around 2.5 volt are above up to 5 volt
