Power supplies are the devices that power computers and servers. They convert AC power from electric utilities into DC power used in most electronics.
What is the 80 PLUS specification?
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 and creates a unique market differentiation opportunity for power supply and computer manufacturers
