Cybenetics ETA SILVER The GV2SE has an ETA Silver efficiency rating, meaning it has a guaranteed typical efficiency of 88%. Cybenetics LAMBDA Not only the efficiency of the power supplies is evaluated, also the noise generated by it. GV2SE series has Lambda grade for certificated silent PSU. 80 PLUS Bronze 230V EU Certified 80PLUS Bronze guarantees 85%, 88%, 85% efficiency with 20%, 50% and 100% load rates, significantly reducing overall system power consumption. The higher efficiency of the PSU means that there is less leakage of current, which means less heat, high frequency noises, and fan noise. HDB(Hydro-Dynamic Bearing) Quiet and Long Lifespan Cooling Technology HDB(Hydro-Dynamic Bearing) has benefits of low noise and long life span It discharges internal that quickly and provides sufficient cooling at a low RPM to maximize stable, safe power supply 120mm HDB Fan 120mm Low-noise fan delivers powerful spin even at a low RPM to quickly removes heat from power supply for optimal cooling performance Active PFC With 99% Maximum Power Factor Active PFC system with maximum power factor of 99% providing consistent and stable output as well as high energy efficiency. High efficiency ensures safe, stable system operation with low component noise, less heat from parts, and minimal fluctuation of power supply. 12V DC-TO-DC Convertor With 100% Availability The power supply supports a wide range of PC components, minimizing variations in output voltage, maximizing 12V DC rail output to provide a stable system operation Built-In High Performance Capacitor That Handles Up To 221˚F Highly reliable capacitor used to supply stable voltage even at high temperatures up to 221˚F Built-In EMI Filter For Noise Reduction EMI filter is installed to suppress frequency that causes noise for better system operation. Aluminum Solid Capacitor All capacitors in the power supply are top quality and very reliable in supplying stable power even at high temperature. Multiple Protection Circuit System Multiple protection circuit system protects your system OTP (Over Temperature Protection) OCP (Over Current Protection) OPP (Over Power Protection) OVP (Over Voltage Protection) UVP (Under Voltage Protection) SCP (Short Circuit Protection) Highly Energy-Efficient Standby Power Supply ZALMAN’s power supply has such remarkable energy efficiency, that during standby the power supply can be kept under 0.5W to avoid any unnecessary power consumption. The power supply has acquired ErP LOT 6 which passed european energy saving standards for environmental friendly and energy efficient experience for users. Eco-Friendly Products All Materials Included Are Environmentally Safe And Harmless. RoHS Compliant Certified products are environmentally safe that do not cause harm to the human body. Certification is received when XRF testing determines that the 10 hazardous substances is below the standard value for the electronic products exported to europe. Unlike other inexpensive products, ZALMAN’s products are produced from the beginning with RoHS standards in mind.
