I was upgrading my fan, and the controller used a SATA power line. So I needed to take out my molex cable from my power supply. I tried to take out my PSU, and it did resisted a bit, but I finally took it out. When I inspected it, I saw that a small bit of my PSU and my Casing paint was scraped, leaving the bare metal of my PSU and Case in view. I did try to clean my PSU housing area on my case, and got as many paint and metal scrappings as possible, but I'm worried whether any metal and paint dust will short out my PSU, should I change the PSU and the case? My PSU is relatively new and I do have a 7 year warranty on it. (Bitfenix Whisper Gold 550W)
