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?
Edit: Better quality image, and new image host added.

I could be wrong, but it looks like the part that came off is in the fenced off area for onboard audio, so it might be ok if you’re using audio from the HDMI on the GPU.

Audio from jack appears… to be working fine. Obviously I am just going by ears and some songs playing, so I can’t tell if some minor frequency or noise is present.
There’s 6 audio ports on the back of the motherboard (which is why it looks like there are extra/redundant parts) and it could be any of them, not just the main stereo (green) output. But if your main audio is working fine, it should be usable.
Yeah, I think it’s the onboard audio. Physical gap to prevent picking up all the noise from the pcie slots.
I’d just check for any components in that area while after it’s running to make sure nothing is getting to hot. If you don’t want to buy a new mb and want to be maybe safer disable onboard audio in the bios. Then use your GPU, find a cheap sound card, or use usb audio.
Something is damaged, but sometimes it doesn’t effect how your using it.

This is definitely not a good way of thinking about electronics. Your motherboard might be fine but assuming identical components are for redundancy is a mistake!
K72s are transistors typically used in power management. I would guess that when it was intact, it controlled power for one or more of the the PCIe slots to the right, or the USB-C port above it.
If the affected port isn’t in use, it probably won’t cause any issues. If the affected port never draws the voltage/current that was supplied by that transistor, it probably won’t cause any issues.
But, this information is worth what you paid me for it…
That would be my assumption.
You don’t see much redundancy in motherboards, so OP is off in that regard.
Rather, a lot of parts are non-critical because not every single one is needed to begin with. Unless you actually populate every single connector and port on a motherboard, a lot of it is doing nothing.
Looks like a mosfet got broken. I am no electro-ologist, but it is probably going to have weird voltages wherever that mosfet serves. Might be okay for a while or maybe not.
If I wanted to save the board, I’d order a replacement from Digikey or elsewhere. Just ID one next to it and order it up. Have a finer tip on the soldering iron and Bob’s your uncle!
Looks like maybe the copper pad came off for one of the contacts.
In that case a resolder might be a pain, and require some extra work to expose more of the trace.
I first read that as “finger tip” and was wondering why you were telling OP to burn themselves
Something something equivalent exchange, user must suffer the way the board suffered, karma and all that
I don’t know enough about motherboards to really say for sure, and hopefully someone more knowledgeable can come in to correct anything, but I’d be concerned if that chipped off piece happens to be part of the voltage regulator module. My call is to play it safe with electronics, because worst case scenario is that it could fry other components or catch on fire
