2 of 4 HDDs not seen after PSU swap

I recently swapped out PSUs and now 2 out of 4 hard drives arent being recognized (1 is an SSD). Why would that be?

Here are the details:
I wanted to add in my old GPU, 1050ti, and run duel GPU's. My old PSU didnt have enough power cables to run both GPUs so I purchased the Corsair. Hooked everything up and nothing. I did some cable chasing and the unrecognized hdd's did not follow the cables, both SATA power and data cables. I then thought maybe the power unit was faulty, so I hooked up a spare PSU my buddy had, an EVGA 750G3, still had the same HDD issues. I then unhooked the power to the old GPU incase for some reason the 750s were not up to the power task, still didnt fix the issue. I took the SSD that wasnt being recognized, put it into an external adapter and connected it to my MSI Laptop. The laptop recognized the SSD, so that ruled out it getting damged some how.

At this point I am pretty stumped. Any help would be appreciated.

Check your motherboard manual on this, but it is possible that the SATA ports your "missing" drives are connected to are being disabled when you put the 2nd GPU in as they share PCIe lanes.
Are the drives still missing if you remove the 2nd GPU?
