NOTE: For more information about supported cooling fans matrix, see the thermal restriction section in Dell EMC
PowerEdge R750 Technical Specifications on the product documentation page.
NOTE: 12 x 3.5 inch and rear drive configuration systems do not support GPU card.
2. Remove the heat sink and install the required t-type heat sink.
NOTE: All GPU cards require t-type heat sink and GPU shroud, irrespective of the length.
3. Remove the air shroud and install the GPU air shroud.
4. Remove the GPU air shroud top cover.
NOTE: The GPU air shroud top cover is part of the GPU air shroud.
5. Remove the GPU air shroud filler.
6. Install the GPU.
NOTE: See expansion card installation guidelines to know about risers and slots that support GPU.
NOTE: For information on riser slot location on the system board, see the System board jumpers and connectors topic.
7. If applicable, connect the power cables to the GPU. To know the connectors for GPU on the system board, see the System
board jumpers and connectors topic.
Refer to the GPU power cable matrix to know about the requirement of cable for the GPU.
