System Power Requirements
Table 14 lists the power requirements for the individual hardware components. The values in this table are listed under typical voltage conditions. The power requirements are the same for both the DC and AC power supplies.
The numbers listed in Table 14 are fairly accurate for larger, typical configurations. When the total power consumption is calculated to be less than 600 watts, you should increase the number by 10 percent because the efficiency of the power supply is lower when supplying less current. The 10 percent reduction at lower power levels is an approximation. The actual reduction in efficiency is nonlinear and depends on the particular mix of PICs.
