• A high performance for energy savings. 80 PLUS Gold Certication: High energetic
efficiency. The 80 PLUS Certication guarantees greater than 87%, 90% and 87%
efficiency at 20%, 50% and 100% operating loads, respectively.
• Japanese capacitors of 105°C nominal provides a quality reliability/performances.
• A single +12V monorail for a better current distribution.
• Active PCF. A correction of the active power factor >0.90 at full load that provides
a clean and reliable current.
• An advanced cable set covering all kind of PC.
• A DC fan of 120mm provides an excellent air ow with a very low noise level. 12V
DC, 66.5CFM/min, <34.5 dB(A), This fan is only for power supply internal cooling
purpose, not for system cooling.
• Hybrid mode:
◦The Normal Fan Control setting (button pushed) enables the fan to rotate
continuously in Silent Mode and Cooling Mode, depending on the system load.
◦The Hybrid Silent Fan Control setting (button not pushed) enables the power
supply to run in Fanless Mode up to 20 % (± 5 %) of the maximum rated
load at 25 degrees. When the load further increases, the fan control will keep
regulating perfect cooling through the Silent Mode or Cooling Modes.
