Power consumption for different FIM-7941F FortiGate-7081F
configurations
The tables in this section provide information about how to calculate maximum power consumption for a FortiGate-
7081F system with two FIM-7941Fs and with two or six FPM-7620Fs.

Power consumption calculation with two FPM-7620Fs

The following table shows that a FortiGate-7081F with two FIM-7941Fs and two FPM-7620Fs would require a power
allocation of 4032W. The capacity of each PSU is 2500W. The system would require two PSUs (2500 x 2 = 5000W). You
could add up to four extra PSUs for redundancy.

To completely power a FortiGate-7081F with two FIM-7941Fs and two FPM-7620Fs you would need two PSUs. You can
add up to four more PSUs to provide 2+1, 2+2, 2+3, or 2+4 redundancy.

Power consumption calculation with six FPM-7620Fs

The following table shows that a FortiGate-7081F with two FIM-7941Fs and six FPM-7620Fs would require a power
allocation of 6896W. The capacity of each PSU is 2500W. The system would require three PSUs (2500 x 3 = 7500W).
You could add up to three more PSUs for redundancy.

FortiGate-7081F 7.0.5 System Guide
These example calculations should be used as guidelines only. In practice, actual power
usage will most likely be higher and the efficiency of PSUs varies for different levels of power
consumption. The maximum power consumption of a fully loaded FortiGate-7081F is 7300W
and the average power consumption is 6100W.
