Electrical Characteristics
All power is supplied to the adapter via the PCI Express 3.3V and 12V rail. Necessary
Voltages are provided by onboard switching regulator circuitry operating off of 12V and
3.3V rails.
Thermal and Atmospheric Characteristics
The maximum board temperature is limited by the LSI SAS2308 IO Processor since it
uses the most power and will be the hottest component on the board.
