I got the SeaSonic G Series SSR-550RM 550W. Whenever I get new stuff I always check the product and when I was looking at the PSU I noticed there was a tiny amount of paint missing on the very corner tip of the PSU. It's maybe the size of like a pin head area missing thick black paint. The PSU and the PC seem to work fine and all but I don't like it's missing the paint. It's not like I see it through the side window but still. Was it dropped maybe ? When I shaked the unit before installing it I I could here a distinct sound/rattle. It's not like it's something loose moving inside but there is a sound rattle though. I assume it's normal could it be a fan bearing ? Would it be dumb to return it ? would you return it ? Am I just being silly.
