How to Choose the Right Power Supply for Your PC?

Often misunderstood, the power supply is a frequently overlooked PC component. While some users choose a PSU on total wattage based on the false assumption that higher wattage means better performance, others settle for whatever comes installed in their PC. When it comes to PC building, coveted components such as the processor, video card or motherboard often grab the limelight, leaving the PSU as a secondary consideration. Buyers often fail to recognize that a good quality, efficient PSU can have significant contribution to the reliability and stability of a system, as well as the lifespan of the components within.

Further complicating the issue for customers in India, there are some power supplies on the market which carry fake '80 PLUS' badges. Even well-known international brands are misleading customers with fake badges. While a PSU may state "Up to 87% efficiency", this is not the same as having achieved real 80 PLUS certification. Full 80 PLUS certification is a rigorous and fixed set of requirements and tests; "up to" results might only be possible at low temperatures or specific wattage loads.

Because of this, it's a good idea to check your PSU is legitimately 80 PLUS certified before you buy, ensuring your computer's power supply can deliver the wattage and efficiency it claims. You can do so by visiting the official 80 PLUS websitewww.80plus.org and searching for the relevant model number or brand. With the entire CORSAIR range of PSUs 80 Plus certified and tested, you'll be sure to find every CORSAIR model officially listed, with precise test results and performance figures, providing complete peace of mind.

What does 80 Plus Certification mean? .

In 2005, Tacoma, WA based Ecova Plug Load Solutions initiated the 80 PLUSยฎ program. In 2007 Energy Star made 80 PLUS certification mandatory in order to bear the Energy Star logo. The 80 PLUS program tests computer power supplies for efficiency at 20%, 50% and 100% loads. Initially, power supplies only needed to be 80% efficient to earn certification. Over the years as power supplies became more and more efficient, new standards such as Bronze, Silver, Gold, and Platinum were created. An 80 PLUS certified power supply is at least 80% efficient, which means in the conversion from AC to DC power, only 20% of power is lost as heat. Below are the different 80 PLUS levels and the efficiency requirements for each level:
