Power supply with poor efficiency draws excessive power and loses large amounts of power into clean thermal energy.

This contributes to heating systems and higher power consumption than necessary. To counter problems of inefficient power supply was started 80 PLUS program by using different performance levels to grade power supplies after visiting their effectiveness.

In the past, the coveted 80 PLUS Gold certification was the best award a power supply could have, but now it has launched a new Platinum label for power supplies with over 90% efficiency.

Power Efficiency at different loads 20% 50% 100%
80 PLUS 80% 80% 80%
80 PLUS Bronze 82% 85% 82%
80 PLUS Silver 85% 88% 85%
80 PLUS Gold 87% 90% 87%
80 PLUS Platinum 90% 94% 91%

80 PLUS Platinum requires that the PSU can keep a competence of 90% at 20% load and the entire 91% effectiveness at 100% load. The only companies that have jumped on the Platinum board is that HP started using Platinum 80 PLUS certified power supplies in their serves, the market where they earn far the most efficient on power supply.

But even the consumer market is expected to follow up with the 80 PLUS Platinum certifications. While we wait for the perfect power supply that delivers a 100 percent efficiency.
