Effizienz war schon immer ein Hauptziel bei der Entwicklung von Stromversorgungen, da Verluste bei der Stromumwandlung im Allgemeinen zusätzliche Kosten verursachen.
Die Macht großer Zahlen
In 2004, the US EPA’s ENERGY STAR programme estimated around 10 billion power supplies in use worldwide — across computers, servers, printers, televisions, phones and more.
Efficiency back then was poor. The same assessment found many designs converting only 30 to 60% of the power they drew, and the prevailing industry design guide for PC power supplies required just 70% efficiency at 50% load.
Certified designs today are in a different class. 80 PLUS® Titanium requires 94% at 50% load on 115 V, and the newer Ruby tier 95%. Cybenetics Diamond, which averages efficiency across the full load range rather than fixed points, requires 95% or higher on 230 V. Seasonic’s PRIME ENTERPRISE RX-1600 is the first ATX power supply certified 80 PLUS® Ruby at 115 V and 230 V.
The historical 70% design-guide requirement and today’s 95% Ruby certification threshold illustrate the difference between those requirements at 50% load. They do not represent the average efficiency of all power supplies in use. For the same DC output power, a more efficient power supply draws less electricity from the wall and loses less energy as heat.
Die Geschichte der Zertifizierungen
Until the early 2000s, power supplies had no efficiency certification, and it was not until 2004 that the first initiative to create an efficiency standard emerged.
The 80 PLUS® program was created in 2004 by Ecos Consulting, an energy efficiency firm, and is today administered by CLEAResult, which acquired the program through Ecos’s successor company.
Sea Sonic partnered with Ecos Consulting at the time to work out uniform efficiency standards, and in 2005 became the first manufacturer to bring the world’s first 80 PLUS® certified PC power supply to market (the Seasonic SS-400HT). Since then, 80 PLUS® certified power supplies have become a de facto component in PC systems.
Effizienz verstehen
Effizienzzertifizierungen helfen den Verbrauchern zu erkennen, wie effizient die Stromversorgung ist.
Der Wirkungsgrad in Prozent ergibt sich aus der Division der Ausgangsleistung durch die Eingangsleistung; je höher dieser Wert, desto effizienter ist das Netzteil. Die bei der Umwandlung verlorene Eingangsleistung wird in Wärme umgewandelt.
Higher-efficiency power supplies often require more advanced designs and components. However, an 80 PLUS® rating specifically certifies energy efficiency, not overall build quality. During certification, the power supply is tested at several load levels, including 100% of its rated output, to verify its efficiency under the defined test conditions.
Cybenetics
Cybenetics ist ein Unternehmen für die Prüfung und Zertifizierung von PC-Hardware. Es wurde mit dem Ziel gegründet, die Art und Weise, wie Netzteile getestet und verglichen werden, zu revolutionieren, um Endnutzern ein klareres Bild der Stromversorgungsprodukte zu vermitteln, die sie für ihre Systeme kaufen.
Die Bedeutung von Messungen
The basic test methodology is that Cybenetics doesn’t take only three or four measurements to define the efficiency or noise output of a PSU. Instead, Cybenetics applies more than 1,450 different load combinations, from minimal to full load, and calculates the average efficiency and noise readings that determine the PSU’s efficiency and noise ratings.
This provides Seasonic with a complete operational map of the PSU, allowing us to evaluate not only efficiency and noise, but also voltage regulation, ripple, and other important performance data.
