The efficiency of your power supply unit is important because it directly affects you system’s performance and your power bill. The efficiency rating does not reflect the quality or reliability of a PSU. It only reflects the unit’s ability to move power from the wall to your components. The higher a PSU’s efficiency is, the lower the total amount of power it needs to power your system. The new Elite V3 series has a guaranteed typical efficiency of 75%.

A power supply unit works by taking power directly from the wall or other fixed power source, converting it to the correct output required by the connected components, and then distributing that power to said components. If any part of this process is interrupted or executed poorly, the connected components and the PSU itself could be damaged. Active PFC uses a circuit to correct power factor leading to reduced total harmonics, corrected AC input voltage, and increased overall efficiency output.
