Heat-Pipe Installed for Maximum Cooling Performance & Ultra Quiet Operation An ultra high performance heat pipe incorporated on the power supply`s main rectifiers enables high load operation even at low RPM for a dramatic reduction in noise levels. Resonant Switching Circuit Design Compared to Two-Forward Switching, a more advanced Resonant Switching design minimizes `switching loss` reducing heat generation, & operates more efficiently by eliminating the need for an output inductor leading to outstanding stability & reliability. 80 PLUS BRONZE Certified High Efficiency Design This power supply is 80 PLUS Bronze certified with 82% minimum/88% maximum efficiency (230VAC, Typical Load) incorporating a high switching frequency & low power loss circuitry design, & guarantees higher efficiency compared to non-certified products. &8251; 80 PLUS is an energy efficiency certification program administered by Ecos Consulting of the U.S.A. Less Than 1W Standby Power Consumption 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 Standby Power Standards (Er P: Energy-related Product) This product complies with Er P Lot 6, the Standby Power & High Energy Efficiency standards of the European Union. Modular Cables Modular cables facilitate simplified cable management & optimal airflow through the computer enclosure for increased cooling performance. ATX12V v 2.3 The latest PSU design standard is incorporated for compatibility with a wide range of CPUs, motherboards, & graphic cards. Quad Rail +12V DC Output Four independent +12V outputs for core components facilitate highly stable operation. Dual Graphic Cards Support 6-Pin & 6+2 Pin PCI-E connectors are provided for dual-graphics card setup. Ultra Quiet 120mm Fan An ultra quiet Hydro-Bearing cooling fan increases airflow while minimizing noise for a superbly quiet computing environment. Active PFC for enhanced Power Factor & Reduced Harmonics By implementing an Active PFC (Power Factor Correction), instead of Passive PFC with a Power Factor (PF) of 75%, the 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. ATX20+4 Pin Main Connector ATX20+4 Pin Main Connector broadens the range of motherboard compatibility. Supports ATX12V CPU 4-Pin & EPS12V CPU 8-Pin Two ATX12V CPU 2 2 (4-Pin) power cables can be combined to form an EPS12V CPU 8-Pin power cable. High Luminance Blue LED Blue LEDs are installed inside the power supply for cool aesthetics. Sleeved Cables All power cables are sleeved for easy cable management & enhanced air circulation inside the computer enclosure. Black Steel Coating The case is coated black which prevents scratches & provides maximum protection. Multiple Safety Features Safety features including Over-Voltage Protection, Over-Current Protection, Short-Circuit Protection, Under-Voltage Protection, & Over-Temperature Protection safely protect the system. Meets WEEE & Ro HS Standards This product complies with the WEEE & Ro HS environmental directives of the European Union. International Safety & EMC Certifications
