Ovation Power Supply – UltraPower Series

80+ is a certification designed to denote that a power supply is at least 80% efficient at different load levels. The efficiency rating is power output divided by the wattage drawn from the wall socket. So a 500w Power Supply with a 50% efficiency rating would draw 1000W. The remaining 500w are wasted as heat during conversion process. The more efficient the power supply, the better its longevity and reliability and oftentimes the better the longevity of the PC as a whole. While the less efficient the power supply, the more heat it will generate. More heat means more wear and tear and a higher failure rate.
