PowerEdge R7525 with 3 GPU cards installed power supply
Dear all,
I am working on a PowerEdge R7525 with TWO GPUs (on Riser1A + Riser3A, by using power connectors #5 and #15）, I am following this documentation, and right now it works well.
I find these comments:
NOTE: A maximum of three full length GPUs with power cables or a maximum of six half lengths GPUs are supported in a system.
I already used power connector #5 (SIG_PWR_3, GPU Power) and #15(SIG_PWR_4, GPU Power) on this document:
If I want to add one more GPU, what other power supply shall I use? Is SIG_PWR_0 (Rear BP) applicable for GPU-- this connector is spare right now.
| 5. | SIG_PWR_3 | GPU power |
| 15. | SIG_PWR_4 | GPU power |
| 12. | SIG_PWR_0 (Rear BP) | Backplane signal and power |

Hello,
please check this page

in the images you can see that you can connect SIG_PWR_0 to the GPU3.

Hello,
Can you provide your riser configuration you have in your system?
It may be best to contact Sales and they can take your criteria and supply the options available.
The GPU FL kit, HL kit, and the GPU power cable kit are three different kits available for the Customer.
Depending on the kit ordered, the respective components are available:
risers, shrouds, fans, heat sinks and cables
GPU kit components Page 224
Riser and GPU slot configuration , GPU power cable matrix Pages 225-226

@DELL-Charles R Thanks a lot for the quick reply.
I am using GPU FL kit， as mentioned, I already used Riser1A + Riser3A, I think Riser4A should be the only left option for the 3rd GPU.
I need to confirm -- what power supply connector should I use for the 3rd GPU?
Does #12 (SIG_PWR_0 (Rear BP)）fit?
