English Protection features 1. Over-power protection The power supply shuts down and latches off when output power is within 120 ~ 150 percent of rated DC output. 2. Over-voltage protection No single point fault causes a sustained over-voltage condition on any or all outputs. The power supply provides latch-mode over-voltage protection as defined in the following table. Output +12V1DC +12V2DC +5VDC +3.3VDC Minimum 13.4 13.4 5.74 3.76 Nominal 15.0 15.0 6.3 4.2 Maximum 15.6 15.6 7.0 4.3 Unit Volts Volts Volts Volts 3. Short-circuit protection The power supply can withstand a continuous short-circuit to the output without damaging or overstressing the unit. The power supply shuts down and latches off for shorting the +3.3V, +5V, +12V1, +12V2, or -12V rails to return. Shorts between main output rails and +5VSB do not cause any damage to the power supply. 4. Over-current protection Overload currents applied to each tested output rail will cause the output to trip before reaching or exceeding 240 VA. For testing purposes, the overload currents should be ramped at a minimum rate of 10 A/s starting from full load. Warning! To reduce the risk of fire, electric shock, body injury, or damage to the power supply and/or your computer system, take the following safety precautions: • Never open or dismantle the power supply! • Do not remove the power supply while the system is on. • Do not unplug the AC power cord while the system is on. • Do not put the power supply where it can get wet. Troubleshooting If the power supply fails to function properly, do the following: • Check if the AC power cord is plugged firmly. • Check if the extension power cord is switched on. • Check if the voltage switch is set to the appropriate position (115V or 230V). • Check if the main power connector is firmly plugged into the socket. • Disconnect the power cord to reset the power supply. Reconnect after 30 seconds or so. For more information, visit the ASUS website at www.asus.com. 4 ASUS power supply
