IMPORTANT:
power cable to obtain the total wattage required.
IMPORTANT:
calculate power supply redundancy rules. For the server to calculate the accurate number of
power supplies needed, use the lowest wattage power cable possible for the high- powered PCIe
card.
For example: if a user installs a 150-W PCIe card in the server and connects it to a 300-W power
cable, the server calculates the power needed as 300 watts instead of the 150 watts the card
uses. This situation results in the server requiring more power supplies than needed for operation
or redundancy when, in fact, the server may be sufficient with fewer power supplies. HP
recommends fully populating the server with power supplies when using high power PCIe cards.
The PCIe slots provide 75W of power. The remaining wattage is supplied by the
