R750xa - Right cables for 12vhpwr GPU?
Hi,
Could anyone point me to the right cable for my R750xa to power a card with 12vhpwr plug?
I've found 1JCMR , but I'm not completely sure it is the right one, and since I know they were sold with H100s, it should be it.
I would love to throw two RTX Pro 6000 Server editions inside the R750xa, choked to +-300W to not overdraw on the plug designed for +-300W.
Thanks!

Hi,
It seems correct part but I guess you need two seperate 1JCMR cables one per GPU in your case. To managed properly your power budget and airflow. But I'm not sure slot compatibility.

@DELL-Erman O Thank you for the confirmation.
Yes, one cable per GPU. As for dimensions, they are identical to the H100 so that shouldn't be a problem.
Once I will have both the cables and the cards on hand, I will respond here back to confirm if the theory is right and all works smoothly.
