What is Cybenetics efficiency level certification?

Cybenetics uses the ETA standard to rate PSU efficiency. The name ETA is derived from the Greek letter “H” which is widely used to represent efficiency. There are six ETA certifications, DIAMOND, TITANIUM, PLATINUM, GOLD, SILVER, and BRONZE, covering an efficiency range from 82%. The ETA standard is very strict, besides the overall power efficiency, it also takes into account the efficiency of the 5VSB rail and the vampire power (power consumption with no load on the 5VSB rail). Thus, when you look at an efficiency-certified unit by Cybenetics, it must be the best unit that is able to pass the ratings. SilverStone is always confident with the quality and performance of our power supplies. Therefore, the idea of having a reputable and experienced power supply testing team conducting detailed testing for certification was a great one that we immediately thought to join upon hearing about it.
