What are the benefits of EMI filtering?
EMI (Electro Magnetic Interference) filters are a required circuit for PSUs, and in a good PSU the EMI filter is well designed. An EMI filter prevents PSU’s electronic noise from interfering with other electronic devices, and vice versa. With poorer-quality PSUs, it is common for “noise” from the PSU to be noticeable computer monitors, TVs or radios in the form of static disruptions when turning on your computer.
