NOTE: PCIe cards must support still air environment and must not require active cooling.
NOTE: PCIe cards rated above 25 W are not supported regardless of temperature rating.
NOTE: If a PCIe card is rated at a temperature that is not shown in the table, use interpolation to calculate the maximum
supported power.
NOTE: If a PCIe card is rated at a temperature greater than 85°C, it shall be treated as an 85°C rated card in
determining the supported power.
