1.  General 
1.1  Scope 
This specification defines the performance characteristics of a single phase 850 watts, 8 
output power supply : +5V, +12V1, +12V2, +12V3, +12V4, -12V, +3.3V & +5VSB,and it 
will provide power to all system components. This specification also defines worldwide 
safety and electromagnetic compatibility requirements for the power supply which is 
intended for use in computer products. 
 
2.  Input Characteristics 
2.1 Input Voltage 
Nominal Voltage 
 
 
     Voltage Variation Range 
--------------------- 
 
   
     ---------------------------- 
100 - 240 Vrms              
                 90 - 264 Vrms 
 
2.2 Input Frequency 
Nominal Frequency   
 
Frequency Variation Range 
------------------------ 
  -------------------------------- 
50-60 Hz   
 
 
 
47 Hz to 63 Hz 
* The power supply must operate at above frequency with 90-264 VACrms input voltage 
range. 
 
2.3  Max.Input AC Current 
Max.Input Current   
 
   Measuring Range 
------------------------ 
  ----------------------- 
11A                                        100-240 Vrms 
 
2.4 Inrush Current 
The power supply must meet inrush requirements for any rated AC voltage, during turn on 
at any phase of AC voltage, during a single cycle AC dropout condition, during repetitive 
ON/OFF cycling of AC, and over the specified temperature range. The peak inrush current 
shall be less than the ratings of its critical components (including input fuse, bulk rectifiers, 
and surge limiting device).
 
2.5 Efficiency 
HP-850-G14C provides an efficiency of 80% minimum when measured at Light Load、
Typical Load and full load under 115V/60Hz & 230V/50Hz  condition.
