Taipei- Taiwan， Feb. 12/ 2010.
ETASIS ELECTRONICS™， a leading technology owner of high efficiency switching power supplies，
officially announces EEFRP-G657 has been certified by 80 PLUS®， an innovative，
electric utility-funded incentive program used to integrate more energy-efficient power supplies into desktop computers and servers.
This power supply comes with fully compelling features providing extremely high efficiency for high performance rack-mount server.

92% High Efficiency
“We’ve reached 92% efficiency.” said Ricky Lin， R&D Director of ETASIS. “Comparing to traditional redundant power design，
EFRP-G657 saves 30% utility cost for customer and improve stability and heat dissipation.”

PMBus Enabled for Managed Server
The Power Management Bus (PMBus) is an open standard power-management protocol with a fully defined command language
that facilitates communication with power converters and other devices in a power system.
The protocol is implemented over the industry-standard SMBus serial interface and enables programming， control，
and real-time monitoring of compliant power conversion products. EFRP-G657 supports PMBus 1.2，
which is latest standard for advanced server/storage power system， which shall includes:
• Input Power Reading
• Input Voltage Reading
• Input Current Reading
• Output Power Reading
• Output Voltage Reading
• Output Current Reading
• FAN Speed Control
• LED Control
• Temperature Monitor

EFRP-G657 has embedded microprocessor and EEPROM transferring data to server controller via SMBus.
The server administrator or system integrator can develop administrative applications to monitor and
control power supply based on monitoring results. The power supply is not a “black box” any more.
It can be managed and controlled by system and improve system reliability.
