I was actually considering something like this for my main desktop computer. I could run a 12/2 or 12/3 wire to my office. I did not consider the TV’s though. I know our 60inch is about 350w, so there could be some savings there, but I’m unsure of its voltage rating. I was able to verify our 40in is only 120v. While drafting this response I noticed my color laser printer out of the corner of my eye and recall the lights flickering when I print, checked this out and only 120v. There are some small potential gains if we start paying attention to it.
