While I was trying to put on my side panel, I noticed that the GPU power cables were touching it and bulging out, so I tried to use a little bit of force and managed to get it closed in, which is what I always do. This time, however, a bit of the cable's insulation tore off (just a very small amount), and I can see a little bit of the cable. Is this safe or do I have to urgently get it replaced? I'm 16 and right now my family's kind of financially deprived so if I came to my mom asking for replacements she wouldn't be too happy. I'm planning to bring the PC with me to college so are there any risks of having a little hole in the cable? Thanks.
