8.3 Electrical Characteristics

All power is supplied to the adapter through the PCIe 3.3V rails and the 12V rail. Onboard switching regulator circuitry that
operates from the 3.3V rails and the 12V rail provides the necessary voltages.
The supply voltages supplied by the PCIe edge connector are 12V ± 8% and 3.3V ± 9%.
Typical power is measured with maximum I/O traffic, typical silicon process material, and nominal voltages operating the
card at an ambient temperature of 45°C with required airflow.The power requirements for the adapter under normal operation
are shown in the following table.

8.4 Thermal and Atmospheric Limits

The atmospheric limits for the adapter are as follows:
Temperature range: 0°C to +55°C (+32°F to +131°F) (dry bulb)

Relative humidity range: 5% to 90% noncondensing

Maximum dew point temperature: 32°C (89.6°F)

Minimum airflow: 200 linear feet per minute at 55°C inlet temperature
