Noise Level of Power Supply

What is Noise Level of Power Supply?

The noise level of a power supply refers to the amount of electrical interference or "noise" that is generated by the power supply as it converts AC voltage to DC voltage for use by electronic devices.

This noise can affect the performance of sensitive electronic components, such as audio or video equipment, and can lead to issues such as static or humming in the output signal. The noise level of a power supply is typically measured in decibels (dB) and can vary depending on the design and quality of the power supply. Lower noise levels are generally better, and power supplies designed for sensitive applications may have additional filtering or shielding to reduce noise. It's worth noting that power supply noise can also be introduced by other components in the system, such as the motherboard or graphics card, so it's important to consider the overall noise characteristics of the system as a whole.
