1. Safety Precautions The following safety precautions and directions for use are meant to prevent accident and injury. Please read thoroughly before using the product. Warnings Serious injury or death can occur. Opening the cover of the product while the power cord is plugged into the outlet can result in electrocution or critical damage to the product. Handling the power cord with wet hands can result in electrocution. Inserting fingers or metallic objects into the cooling fan can result in injury or electrocution. Cautions Minor injury can occur. May degrade product conditions or cause malfunction. Operating in an extremely cold or hot environment can degrade product performance and lifespan. Allowing liquid to get into the product can result in malfunction. Operating in a humid or non-ventilated environment can reduce product lifespan. 2. Components 1) One Power Supply 2) One FAN Multi-connector (ZM-MC1) (For supplying power to an extra fan. See page 5 for details.) 3) One S-ATA power convert cable 4) One PCI-Express VGA SLI sub-Cable for power conversion 5) One Power Cord for AC Power Source (Not included in some countries) 6) One User's Manual 7) Zalman Cable Tie 3. Notes on Installation To ensure safe and easy installation, first read the Safety Precautions above, then read the following notes. Plugging the main power connector P1 into the main board while the product is connected to the AC power source may result in damage to the main board. Do not insert the DC output connectors with too much force into devices as the shape of the connector is meant to prevent incorrect insertion. After installation, if the Power On light on the case does not light up when the main power button is pressed, some devices may be plugged in incorrectly or the main board may be faulty. Please double-check the installation. * For more information on the product, please visit our website at www.zalman.co.kr. -1- 4. The Zalman Advantage With the goal of enhancing your computing environment, all Zalman Tech products are ultra-quiet. This product is an ultra quiet 460W ATX Ver. 2.03 / ATX12V Ver. 2.01 power supply supporting SLI-capable Intel LGA775 Pentium 4 & AMD Athlon 64/64 FX CPU equipped systems. CNPS (Computer Noise Prevention System) with Auto Control Cooling Fan By implementing heat-sensor circuitry that controls the cooling fan's speed (rpm) in relation to the temperature within the power supply, noise has been greatly reduced. The graph below shows the CNPS characteristics of our product. CNPS (Computer Noise Prevention System) refers to a system that reduces a conventional computer's noise (30dB or more) to an inaudible level (20dB or less). In order to create a true noise-free computer, Zalman's other noise-free products should be used together with this product. The graph above shows that the ZM460-APS in "Noiseless" or "Silent" mode can operate when the power supply's internal temperature is kept below 56 . This information is in compliance with the 2nd Revision of ISO7779, an international standard for noise level measurement. Results may vary for different system configuration and/or the test environment. Improving Power Factor & Eliminating Harmonics through Active PFC By implementing Active PFC, the power factor (PF) is improved from 75% (Passive PFC) to 96% (230VAC, Full load), while harmful harmonic frequencies are reduced below regulatory requirements. High Efficiency Design Designed with a high switching frequency and low power-loss circuitry, the efficiency of this product exceeds 80% (230VAC, Full load). * For more information on the product, please visit our website at www.zalman.co.kr. -2- ATX "20+4" - Pin Main Connector ATX "20+4" - Pin main connector broadens mainboard compatibility. ATX12V CPU (4-Pin) & EPS12V CPU (8-Pin) Connectors Use two ATX12V 2*2(4-pin) connectors together to form an EPS12V CPU connector(8-pin). PCI-Express Graphics Card Power Connector (6-Pin) PCI-Express graphics card power connector is provided to high-end graphics card support. EZ Connectors for ODD & HDD EZ Conectors for ODD & HDD for easy connecting and disconnecting of the plugs. Dual +12VDC Output Two +12VDC rails output up to 30A combined, providing more stable power to high-end systems. Sleeved Cables All power cables are sleeved for easy cable management and improved air circulation in the computer's case. Certified with International Safety Approvals & EMC Standards Strict DC Voltage Regulation & Low Output Ripple / Noise The following figures show the ripple and noise measured from the DC output of the ZM460-APS. a) +5VDC (VR&N : 41.3mVp-p) b) +3.3VDC (VR&N : 39.8mVp-p) c) +12V1DC (VR&N : 53.1mVp-p) d) +12V2DC (VR&N : 51.6mVp-p) e) -12VDC (VR&N : 46.7mVp-p) f) +5VSB (VR&N : 40.5mVp-p) Each DC output had a 0.1 F ceramic capacitor and a 10 F electrolytic capacitor attached as the bypass and the oscilloscope (input impedance 1M ) measured the waveforms at 20MHz frequency bandwidth. The waveforms may differ with varying measurement conditions. * For more information on the product, please visit our website at www.zalman.co.kr. -3- 5.
