ZM850-HP is ultra-quiet power supply complies with ATX12V Version 2.2, and supports lastest dual-core CPUs (Intel Core2 series/AMD Athlon64-X2 series), as well as lastest dual graphic card systems.Dual heatpipes with ultra-high cooling performance incorporated on the main heat sources enable high load operation even at low fan RPM for a dramatic reduction in noise levels. By implementing Active PFC (Power Factor Correction), the Power Factor (PF) is improved up to 99% while harmful harmonic frequencies are reduced to meet the Line Harmonic Distortion Requirement of IEC61000-3-2 Class D Specification. This power supply is capable of reaching a maximum of 86% efficiency (230VAC, Full & Typical Load) through its use of high switching frequency and low power-loss circuitry. This product has been certified with the 80 PLUS Power Supply Certification and guarantees a higher efficiency compared to uncertified products. ATX20+4 Pin Main Connector broadens the range of motherboard compatibility. Two ATX12V CPU 2 2 (4-Pin) power cables can be combined to form an EPS12V CPU 8-Pin power cable. Four independent 6-Pin Power Connectors (two 6-pin & two 6+2 pin) provide support for Nvidia's Quad SLI. Modular cables provide organized cable management and improved air circulation inside the computer case. The ultra quiet 2 ball-bearing 140mm fan maximizes the airflow and minimizes the noise level enabling a noiseless computing environment with optimized cooling. The 5Vsb Noise Filter elimin... less
