Two-Forward Switching Circuit Design Two-Forward Switching Design minimizes switching loss & internal heat for enhanced reliability & stability. Active PFC for enhanced Power Factor & Reduced Harmonics By implementing an Active PFC (Power Factor Correction), instead of a Passive PFC with a Power Factor (PF) of 75%, PF has been enhanced up to 99% while harmful harmonic frequencies have been reduced to meet the Line Harmonic Distortion Requirement of IEC61000-3-2 Class D. Ultra Quiet 120mm Fan Ultra quiet 120mm cooling fan increases airflow while minimizing noise for a superbly quiet computing environment. Maximum Efficiency & Energy Savings The energy efficient Green IC circuitry consumes much less standby power (less than 1W) compared to other PSU`s without this feature. Meets Er P Lot 6 2010 Standby Power Standards Meets WEEE & Ro HS Standards ATX12V ver 2.3 The latest PSU design standard is incorporated for ompatibility with a wide range of CPUs, motherboards, & graphic cards. Dual Rail +12V DC Output Two independent +12V outputs for core components facilitate highly stable operation. Dual Graphics Card Support One 6 Pin & One 6+2 Pin power connectors for PCI Express support dual graphics card system. (According to the specifications of Graphic card may not be supported) Design Optimized for Cooling Hexagon-shaped mesh design effective cools the unit & maximizes airflow. Sleeved DC Output Cables DC Output Cables are sleeved for easy cable management & enhanced air circulation inside the computer case. Safe & Stable Power Supply Safety features include Over-Voltage Protection, Short-Circuit Protection, Under-Voltage Protection, Over-Power Protection safeguard the system.
