I have an original Xbox One, large square blocks, and the power went on and off instantly every few months. It left, returned a few months later, and eventually I started looking for a new power supply. The Microsoft brand at Gamestop was about $50 and then I stumbled across this one, read good reviews and took a chance. It arrived within 3 or 4 days (perfect but still very fast delivery) and completely solved the problem. Now I can get back to gaming, Netflix, etc. without worrying about downtime and random power outages. No noise complaints, just unpacked, plugged into Xbox and outlet and my problem was completely solved. Definitely give it a try if you're struggling like me. Just check the photos and make sure the connection matches. 10/10 for me
