Broke transistor on motherboard but everything is still working fine, should I be worried ?

Hello fellow experts,

I accidentally broke a transistor on my msi mpg x570 gaming plus motherboard after trying to remove the pcie lock with a screwdriver to release my graphic card (that was, from the start, a really bad idea).

After panicking for a bit I tried to turn on my PC and to my big surprise everything went fine. I haven't noticed any performance degradation, all my components are detected without any issue.

So I would like to know exactly what i broke and if I should be worried gaming without this transistor ?

Thanks a lot
 
Without a diagram/schematic of the board it's just guessing what it's related to. If it doesn't affect performance then just be happy and more careful next time :)

well, the transistor was there for a reason. Can you read the markings and find out what kind of part it is.

Are there similar transistors in the same general area of the board as the one that broke off?

I'm sure it was there for a reason. But OP is not going to re-solder it so if everything he uses works its best to just leave it alone.
 
From the position of that transistor and the stuff around it, it looks like it's related to some DDR4 power rail.

OP may be very lucky, it looks like that transistor may have not been used in an active circuit, because several component positions around it aren't populated. Sometimes motherboard manufacturers partially populate circuitry that isn't being used on a revision of the board for whatever reason.

But even if OP wanted to resolder that transistor, it wouldn't be possible without extensive surgery on the board. One of the pads was ripped clean off the board, and it looks like a trace and potentially a VIA went with it.

Like Furious said, leave it well enough alone if the board works and remember not to do this again.
