Repairing a PC Power Supply | EVGA NEX650G

I have this faulty modular ATX PSU which does not work. The PSU just start to turn on, but immediately shuts down. I will show how I try to fix / repair this specific PSU.
The chipset is FSP6600 / FSP6601 - look for R76 - should be 10R.

I just got this recommended and I have no idea what I watched but it looks interesting

[@made.by.morten.laboratories]

This is just some hobby regarding repair of a computer powersupply

[@roasthunter]

I have the same PSU which seems to have stopped working, I need to open it up and check, will be interesting if my one has failed the same way.

[@made.by.morten.laboratories]

Yes very interesting indeed, please share your findings :-)

[@user-hi8js3fh5q]

Great repair, seems to be a common problem with the FSP6000/6001 chipset

[@made.by.morten.laboratories]

Thank you for nice comment :-)

[@henfre6845]

Amazing video. Perfectly explained in denglish 😉 My computer is up and running again, so thank you very much Morten 😁😎🎉🎊

[@made.by.morten.laboratories]

You are very welcome, it was a pleasure to do the repair :-)

So, what caused the resistor to fail?

[@made.by.morten.laboratories]

That is a really good question. We dont have a datasheet for the FSP6600/FSP6601 chipset and we don't have any schematics where the ICs are used. I have read that it could be some kind of a bootstrap resistor. I have also seen some designs where C90 (500nF) capacitor to GND after the 10R resistor is not there at all - one report said that this capacitor was getting very hot and was removed after the PSU was working perfect again. So its a bit inconclusive at the moment.

@@made.by.morten.laboratories I guess we'll never know. It works again so that's good.

[@made.by.morten.laboratories]

@@1pcfred Yes let see if the fix will be working over time 🙂

[@1pcfred]

@@made.by.morten.laboratories if it doesn't what's a SMD resistor cost? A fraction of a cent? Granted it's a bit of a pain to replace it. Still you know I'd be in there doing it. Mod it so the resistor is outside. The speed fix.

[@made.by.morten.laboratories]

LOL, if it stop working I will also remove C90. Do you do repairs on PSUs?
