Typical power is measured under the following conditions: 25°C Ambient, 35% total link usage on all ports, typical voltages defined in Table 16
Maximum power is measured under the following conditions: 70°C Ambient, 85% total link usage on all ports, maximum voltages defined in

Note 1: The above power consumption assumes that all ports are functioning at Gen2 (5.0 GT/S) speeds. Power consumption can be
reduced by turning off unused ports through software or through boot EEPROM. Power savings will occur in V

off port is close to zero. For example, if 3 ports out of 16 are turned off, then the power savings for each of the above three power rails can be
calculated quite simply as 3/16 multiplied by the power consumption indicated in the above table.
Note 2: Using a port in Gen1 mode (2.5GT/S) results in approximately 18% power savings for each power rail: V
