I have a high pitched squeal/whine coming from my power supply.  It is most noticeable during gaming but can be heard watching all content.  Seems to happen during bright fast moving content.  I linked a video.  This has been happening since out of the box, purchased 1 week ago. https://www.youtube.com/watch?v=pkDewwHXUbY
