There has been this box in one of my outlets that has been here since I moved in and just now took it off and it says it’s a Class 2 Power Supply. Not an electrician, but why is it there?
In: Technology
The power supply provides usable electricity to the rest of the computer parts. The standard wall outlet has too high of a voltage for your more delicate components (like little capacitors, microprocessors, etc) so the power supply serves as a bit of a gatekeeper to make sure that the current from your mains electricity doesn’t fry your components. It’s a lot like the charging bricks that plug into the wall and use a USB cable to charge a cell phone.
