R720 internal SATA power cable

Hello!

I have an R720 and i'm trying to connect a SSD to the internal sata port. Unfortunately, my server didn't come with a DVD drive and it's respective cable (i think it's P.N. G8TXP ). Been searching for a few days for a cable, couldn't find one in my country but i found something similar.

Unfortunately, it doesn't work. Once i connect the SSD, the server just shuts down like there's a short circuit somewhere.

I noticed that the 4 pin i got only has metal connectors on two of them and from what i can see online in the pictures of the original cable, all 4 pins have metal connectors.

So i'm wondering if this is the issue or is there a jumper on the mainboard that prohibits taking power from that port?

Thank you!
