Repairing a PC Power Supply | EVGA NEX650G

[@martinjensen-d2j]

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

[@made.by.morten.laboratories]

Thank you for nice comment :-)

[@Slimoti]

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 :-)

[@roasthunter]

@@made.by.morten.laboratoriesI’ve had a look and mine appears to be exactly the same, same very hot area, my resistor was measuring high on the board and I removed it but it went flying when I went to check it on the bench, so you know what type I need to order to replace it, I’m not very good with smd components

[@made.by.morten.laboratories]

This is a 10ohm resistor

[@roasthunter]

@@made.by.morten.laboratories thanks have ordered some

[@roasthunter]

@@made.by.morten.laboratories hey I installed a new 10ohm and is working fine again now. How did you know it was 10ohm did you have some schematic? Thank you for your video by the way, it would have taken me much longer to fix without this.

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.

[@1pcfred]

@@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?

[@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 :-)
