Anyone with a Cisco UCS C240 server that runs a GPU?

I can't find a cable for my C240 M5 and Nvidia P40 GPU, so I bought an HP branded one that should work. But I was hoping someone here may have a C240 with the 10-pin aux power on the riser(s) that also run an 8-pin Nvidia GPU that could take a pic of their cable and/or quickly diagram which pin goes to which to ensure the HP cable is going to work and not damage the GPU. I wouldn't think Cisco or HP wouldn't deviate from PCIe standards, but I've been wrong before...

Thanks!
