Efficiency of Power Supply

What is Efficiency of Power Supply?

The efficiency of a power supply is a measure of how effectively it converts AC power from a wall outlet to the DC power needed by electronic devices.

In general, a more efficient power supply will waste less energy as heat, resulting in lower energy costs and a smaller carbon footprint. The efficiency of a power supply is typically expressed as a percentage, representing the ratio of the power output to the power input. For example, if a power supply has an efficiency rating of 80%, it means that 80% of the electrical energy it draws from the wall outlet is converted into usable DC power, while the remaining 20% is lost as heat. Efficiency can vary widely depending on the design and quality of the power supply, as well as the load being placed on it. In general, power supplies tend to be most efficient when operating at or near their maximum rated load, while efficiency may drop off at lower loads. The efficiency of a power supply is an important consideration for both cost and environmental reasons, as a more efficient power supply will use less energy and result in lower electricity bills over time. Many modern power supplies are designed with efficiency in mind and may carry efficiency ratings such as 80 Plus, 80 Plus Bronze, 80 Plus Silver, or 80 Plus Gold, indicating higher levels of efficiency.
