Zalman’s CNPS products enable a noiseless computing environment, in accordance with our policy of developing people-friendly products. This ultra-quiet power supply complies with ATX12V Ver2.2 and supports the latest dual-core CPUs(Intel Core2 series/AMD Athlon64-X2 series), as well as the latest dual graphic card systems(NVIDIA® SLI®-Ready Certified).   * CNPS (Computer Noise Prevention System) refers to a system that reduces a conventional computer’s noise level (30dB or more) to an inaudible level (20dB or less). Zalman’s noiseless solutions enable the user to build silent/ultra-quiet computers of the highest quality.         Dual Heatpipes Installed for Maximum Cooling Performance and Ultra-Quiet Operation A heatpipe with ultra-high cooling performance incorporated on the power supply’s main rectifiers enables high load operation even at low RPM for a dramatic reduction in noise levels.   Improved Power Factor & Reduced Harmonics through Active PFC 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.   High Efficiency Design and 80 PLUS Certified 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. * 80 PLUS is an innovative, electric utility-funded incentive program that strives to integrate more energyefficient power supplies into desktop computers and servers.   ATX20+4 Pin Main Connector ATX20+4 pin main connector broadens the range of motherboard compatibility.   Supports ATX12V CPU 4-Pin and 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.   6 Pin Power Connector for Two PCI Express Graphic Cards Two independent 6-Pin power connectors fully support Nvidia’s SLI.   Module Cables Modular cables provide organized cable management and improved air circulation inside the computer case.   Ultra Quiet 120mm Fan The ultra quiet 2 ball-bearing 120mm fan maximizes the airflow and minimizes the noise level enabling a noiseless computing environment with optimized cooling.   Four Independent +12VDC Outputs Four +12VDC rails supply power independently to the CPU, VGA, motherboard, and peripheral components for the highest level of stability and performance.   EZ Grip Connectors for ODDs & HDDs EZ Grip Connectors for easy removal of the plugs from ODDs & HDDs.   Gold-Plated Terminals and 16AWG Wires All connector terminals are gold-plated to minimize contact resistance and power lose. 16AWG (thicker than 18 AWG)wires are incorporated to minimize voltage drop during high load operation.   Sleeved Cables All power cables are sleeved for easy cable management and improved air circulation inside the computer case.   Multiple Safety Features Over-Voltage Protection, Over-Current Protection, Short-Circuit Protection, Under-Voltage Protection, and Over-Temperature Protection.   Internal Blue LED Blue LEDs are installed inside the power supply for cool aesthetics.   WEEE & RoHS Complies with WEEE & RoHS environmental directives of the European Union. - WEEE (Waste Electrical and Electronic Equipment) - RoHS (Restriction of Hazardous Substances)   International Safety and EMC Certifications

Zalman affixes a Computer Noise Prevention System (CNPS) mark to all components used for noiseless computers.

Plugging the main power connector P1 into the motherboard while the product is connected to the AC power source may result in damage to the motherboard. Make sure that the connectors are connected to their designated locations, and that the connectors are not oriented in the wrong direction when connecting the DC output connectors. If the Power On light fails to light up when the main power button is pressed after completing the installation procedure, then some devices may be plugged in incorrectly or the motherboard may be faulty.
