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.
Note: The PCIe AUX
6-pin connector is not compatible with an ATX12V/EPS12V power cable source. Ensure
that the appropriate PCIe auxiliary power
source is available, and not an ATX12V/EPS12V power source.
Figure 1. AUX Power Connector Location
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.
