The Alveo accelerator card has a 2x3 PCIe AUX power connector which can provide 75W additional power. While the card will operate with or without AUX power, application power requirements identified by the application designer will dictate the need for AUX power. The location of the PCIe AUX power connector is shown in the following figure.
The following table shows the maximum electrical power available with and without AUX 2x3 power cable connected. At a minimum, the 75W PCIe slot power is always used.
