Is my motherboard safe to use after jumping a capacitor?

TLDR in bold text.

In the process of switching out my motherboard I had a screwdriver slip & break off what I assume to have been a capacitor/resistor/fuse.

The motherboard did not want to boot after that so in the end I just soldered the 2 pads together. Everything has been working fine & I stress tested the 1st M.2 & PCIex16 slot by running scrubs with 2 NVME SSD's (these are the 2 slots I'd assume to be affected).

This system is my NAS & I plan to have it run 24/7 for many more years; my question is what kind of issues I could expect? I assume possible dropping out issues or weird errors (if anything), I just hope that it wouldn't kill an eventual SSD I'd have installed in those slots (maybe even an NVME RAID card down the line...)

I will provide the images of the area down bellow, as well as the best resolution third party photo of how the motherboard is supposed to look. I'd love to hear what anyone has to say :)

(Oh and after contacting Asus, they did not provide information/schematics on the affected area, so I don't know what I broke off for sure.)

Motherboard: Asus ROG X570-F

@domentv the component you have "lost" is reference designator PR3018 and it is a 1K ohm 1% 1/16W resistor in a 0402 package and it is part of the P_1V2_IN_1-_10 Net. Looking at the tolerance of 1% that is pretty tight for a resistor. I'd be concerned not having it on there. If you want to use the motherboard for any length of time, I suggest you replace the component and make this a proper repair instead of applying a jumper. Never a good idea when it comes to missing components ;-)

Wow, that's amazing to know! I'll be ordering the resistor & then attempt a proper repair! Thank you so much!!

May I ask how you found out this sort of information? I attempted a few searches, but nothing came up (also assumed the info isn't available), so I then contacted Asus where I got told that they don't give out that sort of information... like most companies these days unfortunately >:3

@domentv as a hobbyist, i do rely on the schematics for my repairs and over the years I managed to accumulate a few. Luckily I had the one for your board model. ;-)

Just ordered this 100pcs lot for 0,54€ https://gyazo.com/043a2fe868601f49150e86...

- 0402

- 1% 1/16W

- 1K ohm

Thanks again, I was particularly annoyed by this blunder of mine as I'm planning to use this motherboard far longer than any "normal" system as this is my current NAS/Server & will down the line become my backup NAS... so many many years ahead & now I know I can actually fix it for sure :D

@oldturkey03 Very lucky for me then. I also found some "legit" files while searching... but they were also pay walled & didn't really seem all that "legit" :P

par

@domentv yup. A lot of those are really not all that grat and it will take a while before you know who you can trust in that business. There are a lot of places that will sell you anything even the wrong or incomplete schematics. Anything for a buck I guess :-)

well heres the thing you dont jump a capacitor as 1 side is a voltage rail and 1 side is ground, a capacitor is not a fuse. so you possibly made the issue worse.

Thank you for letting me know, turns out it was a resistor.

Originally I decided to do the jump as the motherboard wasn't booting at all & I unfortunately don't have any local repair of this sort available... not the smartest move for sure, but I thought better then just replacing it (as a repair would most likely take longer & be almost as much as a brand new B550... likely more than a used B550 motherboard)
