SATA Power in server

I have a Quanta QSSC-2ML server (http://natex.us/quanta-qssc-2ml-foxconn-reworked-da0s2mmb8b0-motherboard/), currently with 4 hard drives attached to the backplane.
I'm looking for a solution on how to add more drives to it, there is the space and there are open SATA and SAS ports, but there are no power adapters of any kind not being used.

I was told to splice power from somewhere else, but I'm not sure where..

The server has an unused PCIE x16 slot, but I can't seem to find any adapter that gives you SATA power from a PCIE slot, even though they can provide up to 75w I believe. The closest thing I can find is this (https://www.amazon.com/dp/B0090IA3AU/), but it's only got one drive slot, and it's for a 2.5" drive. I just need 2 (preferrably 4 if possible) SATA power plugs for 3.5" drives, in the end.
Another thought was taking something from the fan power, but not sure if that's enough power for the hard drives, or even the right voltages.

The last thing I can think of, is to take one of the 4 drives off the SATA backplane, use a sata extender, and then various sata splitter/extender cables to power 3 drives off that one backplane port. I have no clue if the SATA extention/splitter cables can fit into the backplane ports, however.


Thanks for any insight/ideas!
 
Solution
SATA power connectors are same for SAS and SATA, Disks don't use too much power so you could get splitters and have two disks on one cable. It must be done from PSU side, PCIe and slots like that don't provide right voltages. SATA 3.5" disks need 12v, 5v and sometimes 3.3v too.
