Broken inductor on RX 570

Jamie42 · March 4, 2021

So, this card doesn't work. After taking it apart I found this broken inductor reading R68 804 RFC, I would like to replace it but I don't know with that chip to replace it. Could you help me out?

I have no idea. I bought this card broken, hoping it would be a MOSFET or something to do an easy repair on, but I never saw this before.

well, you have 2 possibilities.

the inductor die by itself (this can happen if borderline spec, and so) and pray everything behind/after it doesn't die... (and i don't believe it... specially what is connected at her output.)

the second is evrything behind and after it died too...

but first, you have to track on what it's connected, desoldering it, and see at least, if the converter behind it still provide normal voltage (not 0V or 12V)

R68 mean 680 nano henry, for her value.

then, you mostly have to guess how many amps could go trhu it, depending on what is the load.
