As a person who just isn’t very tech friendly, I found this product super easy to install. I had taken my husbands computer into geek squad who diagnosed the power supply had gone out. With a little help from YouTube, I was able to buy this power supply and go home and switch it out. Took about an hour as I went in not really having any idea what I was doing. Computer runs great now, very happy with this product! Only gave it a four star because I think it should come with better install instructions.
