GPU Card Installation Guidelines
NOTE: Internal GPU cards are supported on the PowerEdge R720 and not on the PowerEdge R720xd.
NOTE: Due to the high power consumption of GPUs, the ambient system inlet temperature is restricted to 30 °C to
ensure adequate system cooling when one or more GPU cards are installed in PowerEdge R720. Note that this is
less than the standard environmental specification of 35 °C.
• The PowerEdge R720 must be installed with two processors.
• The processor must be of 115 W or less.
• The processor must use a GPU kit low-profile heat sink.
• Ensure the GPU enablement kit is available.
GPU enablement kit includes:
– Low-profile heat sinks
– System board support brackets
