Adding Drives to 7820 - NO SATA Power

Question

Trying to add 2 or more drives to a 2nd RAID in Precision 7820. ( ServiceTag: )

I have a Raid 10 4x2TB SSD Drives in the 4 bays.

I have 2 drives I'd like to setup as a RAID 1.

There's a Video on buying a bracket to inset in the 5.25" Drive Bay but it shows connecting the Fan power but NO SATA cables shown.

The Motherbord shows 8 SATA Data Ports, but NO SATA Power ports. How do I do this?

I connected the additional RAID SATA Cables below to RAID card.

But I need 4 or at least 2 more SATA Power cables.

I tried to Use the GPU power cables and I purchased many adapter cables PCIe 6 Female to Female so I can use a PCI-e to SATA Power and no luck! I'm really stuck... Help please.

BTW if you're looking for a Part # for the 2 Drive expansion: 88PWP

and 2 Trays: 1B31P6100-600-G + (N701D)

I have been trying to do the same thing since Dell admitted that the Mega Raid board can not support a boot drive and RAID configured drives. They told me to buy the same kit and they sent me a SATA power splitter but after 2 weeks of trying to get help from Pro Support as to where to plug the power splitter in, I was told by Resolution Manager that I needed to find a local computer tech to do the change if I was capable.

I'm done with buying Dell computers.

Please try to check 'under' the psu, as area. There should be a sata power cable hidden there

Sounds Like you are missing the sata power splitters https://www.amazon.com/Genuine-Dell-FOXCONN-SPLITTER-Desktop/dp/B00T74H5OE/

Getting power from the PCI Express powers for the GPU was the easiest one.
