So, I had some issues with installing the GPU in the case, and the GPU bottom (those metals things at the bottom) ended up scratching part of the motherboard. From what I can tell, there’s a bunch of similar components all the way up, so I’d think there’s redundancy, so I guess it’s not that important. Here is a picture:

PC boots fine into bios, fans work, stuff are recognized, mouse and keyboard also works, but I haven’t really done much beyond that.

Motherboard is: MSI B650 Gaming Plus Wifi

It’s located here, and on them, it is written K72 then vertically smaller K2 (the 2 has an underline):

Should I get a new motherboard?

    Are those near a connector (maybe on the other side?)

    Could be a bunch of ESD protection diodes which only come in to play if you wear socks on carpet and touch the connector terminals.

    Can you provide the numbers listed on the parts? Usually just 3 numbers/letters.

    Also, looking at the circuit traces, does it look like all three terminals are connected? Is one connected to the ground plane? (The copper that covers most of the board surface around the circuit traces).

      From the TI briefing note:

      Paralleling power metal-oxide semiconductor field-effect transistors (MOSFETs) is a common wayto reduce conduction losses and spread power dissipation over multiple devices to limit the maximum junction temperature.

      It would also provide redundancy in case of a failure—if you had only one, and it failed (or was scraped off by an over-enthusiastic GPU installation), you would probably not be going to space today.

        So I guess, what this means is having one scrapped off or failing isn’t a big issue (because of built-in redundancy accounting exactly for that)?
