Efficiency rating: This determines how much energy your power supply uses to deliver the necessary wattage to run your computer. Most power supplies have efficiency rating of 70% or higher at full load.

Cooling: The more wattage available, the more heat is produced. The power supply must have at least one 80 mm fan to cool the system....
