What is an 80 PLUS certified power supply?
Power supplies are the devices that power computers and servers. They convert AC power from electric utilities into DC power used in most electronics. The 80 PLUS performance specification requires multi-output power supplies in computers and servers to be 80% or greater energy efficient at 20%, 50% and 100% of rated load with a true power factor of 0.9 or greater. This makes an 80 PLUS certified power supply substantially more efficient than typical power supplies.
