Corsair TX-750 problem with finding component
Hello guys i have opened a dead Corsair psu and i found a burned ic with 7 pins. Because i can't find any schematics for this PSU ,I said to ask a question here. Thanks in advanced!

Re: Corsair TX-750 problem with finding component
I have a Corsair CS750M and it uses a TNY278pn. Im not sure if its the same. Maybe you can check the datasheet and see if it fits.
Usually, when those components explode, it means there is something in short...
On the side of the big capacitor there is a resistor that seems to be broken. Did you checked that? -
Re: Corsair TX-750 problem with finding component
First of all thanks for the fast reply, i appreciate that! No i did not see that but i needed to find first the ic and then watch around the board for other component defects. Hmm you mean the little one next to the rectifier capacitor?(big one) do you know the value for this too?Comment

victorcas Do you have a schematic diagram for your PSU?Comment

Re: Corsair TX-750 problem with finding component
The top of the ic was likely still in the case somewhere, did you check? Check the trace side of the board, if it is a TNY278pn, pins 5~8 (source) are connected together.Last edited by R_J; 11-06-2021, 06:04 PM.Comment

Re: Corsair TX-750 problem with finding component
IIRC, I have a later TX (TX850M) with much better cap choices.
IIRC, that one doesn't look better than a later CX, cap-wise.Last edited by RJARRRPCGP; 11-07-2021, 01:11 AM.ASRock B550 PG Velocita

Re: Corsair TX-750 problem with finding component
No, I have no idea... It seems to be a 1/2W resistor with a 1% tolerance. It may be used for current measurement. The value is impossible to read. It looks something like "green - brown - ? - ? - brown". You can check it with a multimeter to see if it is actually broken.Originally posted by johnis82 View Post
No. It is almost impossible to find a schematic of a modern power supply, especially the Corsair ones. I think the only way to find out the broken components is to compare it to another Corsair PSU.Originally posted by johnis82 View Post
That power supply seems to have a single layer PCB, so you can follow the traces and try to draw a schematic. With that, you might be able to find compatible components.Comment

Thanks for the info guys i'll open it again and see if i can find anything.
Thanks again for your time
