System Power Specifications
Table 1-4 and Table 1-5 list the AC power requirements for the HP Integrity rx8620 Server. These tables
provide information to help determine the amount of AC power needed for your computer room.
1. “Maximum theoretical power” is used to describe input power at the ac input. It is expressed in Watts and
Volt-Amps to take into account power factor correction. The calculated sum is the maximum worst case
power consumption for every subsystem in the server. This number will not be exceeded by a properly
functioning server for any combination of hardware and software.
2. “Marked electrical power” is the input power measured at the ac input expressed in Volt-Amps. The
marked electrical power is the rating given on the chassis label and represents the input power required
for facility ac power planning and wiring requirements. This number represents the expected maximum
power consumption for the server based on the power rating of the bulk power supplies. This number can
safely be used to size ac circuits and breakers for the system.
