Xbox started randomly shutting down mid-game. For example, he plays normally, but then suddenly lacks strength. It looked completely random. Sometimes I made it after 2 minutes of playtime, sometimes after 2 hours of playtime. This was the case for all games, so there were no glitches in any particular game. After a little research on the internet I came to the conclusion that it could be the power supply unit. Decided to try it and bought it. Here it is! Xbox is now working properly. The fan is a little louder here, but it's not really noticeable when you're running a movie or game.
