Understanding Power Supply Efficiency
Power supply efficiency is expressed as a percentage, indicating how much of the input power is converted into output power. For instance, an efficiency rating of 80% means that 80% of the power is used effectively, while 20% is wasted as heat. Higher efficiency ratings not only reduce electricity costs but also minimize heat generation, improving the lifespan of components.
Popular Efficiency Ratings Explained
1. 80 PLUS Ratings
The 80 PLUS certification program categorizes power supplies based on their efficiency at different load levels (20%, 50%, and 100% of rated capacity). The tiers include:
- 80 PLUS Bronze: 82% efficient at 20% and 100% load, 85% at 50% load.
- 80 PLUS Silver: 85% efficient at 20% and 100% load, 88% at 50% load.
- 80 PLUS Gold: 87% efficient at 20% and 100% load, 90% at 50% load.
- 80 PLUS Platinum: 90% efficient at 20% and 100% load, 92% at 50% load.
- 80 PLUS Titanium: 94% efficient at 20% and 100% load, 96% at 50% load.
