PCIe slot power
Each Slot is designed to allow 75W for each card edge connector. In addition to this there are a total of two auxiliary PCIe power
connectors available-one each for Riser1 and Riser 2. Riser 1C/2C and 1D/2D auxiliary PCIe power connectors are populated on the
riser itself, whereas Riser 1A/2A/1B/2B connect to auxiliary power connectors on the system board.
