## Power consumption for different FIM-7921FFortiGate-7121F configurations

The tables in this section provide information about how to calculate maximum power consumption for a FortiGate-7121F system with two FIM-7921Fs and with four, six, or ten FPM-7620Fs.

### Power consumption calculation with four FPM-7620Fs

The following table shows that a FortiGate-7121F with two FIM-7921Fs and four FPM-7620Fs would require a power allocation of 5458W.

• The capacity of each AC PSU is 1800W (90% of full capacity of 2000W). To completely power a FortiGate-7121F with two FIM-7921Fs and four FPM-7620Fs you would need four AC PSUs (1800 x 4 = 7200W). You can add up to four more AC PSUs to provide 4+1, 4+2, 4+3, or 4+4 redundancy.

### Power consumption calculation with six FPM-7620Fs

The following table shows that a FortiGate-7121F with two FIM-7921Fs and six FPM-7620Fs would require a power allocation of 6890W.

• The capacity of each AC PSU is 1800W (90% of full capacity of 2000W). To completely power a FortiGate-7121F with two FIM-7921Fs and six FPM-7620Fs you would need four AC PSUs (1800 x 4 = 7200W). You can add up to four more AC PSUs to provide 4+1, 4+2, 4+3, or 4+4 redundancy.

### Power consumption calculation with ten FPM-7620Fs

The following table shows that a FortiGate-7121F with two FIM-7921Fs and ten FPM-7620Fs would require a power allocation of 9754W.

• The capacity of each AC PSU is 1800W (90% of full capacity of 2000W). To completely power a FortiGate-7121F with two FIM-7921Fs and ten FPM-7620Fs you would need six AC PSUs (1800 x 6 = 10800W). You can add one or two more PSUs to provide 6+1 or 6+2 redundancy.
