Question What proprietary SATA cable is needed for HP?

[Bpetk7]

Desktop PC HP Prodesk 600 G5 SFF

So I want to add a second SSD to this system correctly, however, the Sata cable that's currently installed(L12241-001) only allows for one SSD and power cable for CD-ROM.
What proprietary HP cable allows for dual ssd with power for cd-rom?

P.S. I currently have a 2nd SSD already installed but I'm using a Sata to USB cable to accomplish the same objective, but this is somewhat hinderful as I have to leave the case open!
I've seen Sata cable 710825-001 but I'm not sure if it's the right one.
I posted this in the HP Community Forum but 2 weeks later, I have no reply/suggestion.
NOTE: THIS IS THE CABLE THAT PLUGS INTO THE PORT CIRCLED IN PICTURE BELOW!

There are only 3 SATA ports in that picture (all a shade of blue). The circled connector is for powering the motherboard only.

So, I'm no technician but I am computer savvy and maybe this an HP thing but that IS a SATA POWER cable connector. Obviouslt it's for power side only but it IS for one SATA and one CD-Rom power. So, I guess, to be more precise, I need the cable that supplies power to TWO SATA and one cd-rom.

Assuming the end on the left is a standard SATA power connector, one of these will work off that:

Thanks to propriety setups " thanks HP" there are a few boards that routes there power supplies SATA through the motherboard. So these power supplies have no SATA power cables at all. You have to pull it from the motherboard.
