I have an HPE ProLiant DL180 G6 server where I would like to install an old Radeon HD 7770 GPU.
Here’s a picture of the server taken from above:
The server came with two PCIe risers; one is used for an HBA, the other provides two PCIe slots (I assume both are x8, and one of them is used by an NVMe-to-PCIe adapter).
The GPU would then be installed in the free slot on the second PCIe riser, in the lower right corner of the chassis.
Here’s a couple of pictures of the location where the GPU would be installed:
I have the following questions:
The GPU must be powered with a 6-pin connector
but the only spare cable that comes from the PSU is a CD power cable
Is there an adaptor that I can buy to power the GPU?
If not, since the server allows for two PSUs (and currently only one
is installed), can I buy a second PSU to power only the GPU?
The second PCIe riser is surrounded by a metallic cage, which would
prevent me from installing the GPU. Would it be possible or dangerous
to completely remove it? It seems to serve as a physical supports for the PCIe risers.
If I’m not mistaken, the GPU would be installed on a PCIe 2.0 x8 slot. Would performance
suffer a lot from this, especially if in the future I changed it with a modern GPU?
