{262} Computer ATX Power Supply Repair / How To Repair Computer PSU, Not Turning ON

in this video i demonstrated Computer ATX Power Supply Repair / How To Repair Computer PSU. i explained in Urdu hindi language. this power supply was not turning ON so there was no output voltage on 5V SB (standby voltage). while testing i found the fuse open circuit and 2x rectifier diodes were short circuit, which caused to blow the fuse. after replacing the diodes i demonstrated how to verify the dc rail and how to test bridge rectifier test by cold testing method, and then i applied the line voltage to the power supply. it started working normally

How much DC voltage must be in between first two capacitors ? I am greeting only 304v DC across two capacitors ,is that okay?

[@haseebelectronicsurdu]

input supply voltage * 1.414 = VDC on dc rail.
divide VDC /2. approximately equal voltage will on each capacitor
if voltage are less, please check both polar capacitor and series coupling capacitor (ceramic capacitor connected at common point of both capacitors and transformer winding)

[@aboothahiru6354]

@@haseebelectronicsurdu Series capacitors that -two big capacitors after bridge rectifier ? replaced it with another 330uf 250v ,but less voltage and SMPS noise at higher loads
