PCI-e cables, JPWR2 and GPU help

[King_of_Connacht]

I need help with where and how I should plug in my pci-e cables into the GPU and "JPWR2" on my motherboard. I have just moved all of my PC components into a new case and I am stumped on this last part. I have forgotten where I plugged the pci-e cables from last time. The cables don't seem to fit correctly into either the GPU or the "JPWR2."

My mobo is an MSI 970 Gaming and my GPU is an AMD Radeon r9-390.

Here are the images of the pcie- cables I have to work with and where I need them to plug into:

Reminder: I am using the same pci-e cables from before and they should work somehow. The plugged in fine before I moved my PC parts into the new case.

The PCIe cables (the part with the 6-pin with 2 pins hanging off) plug into the GPU. The other end goes in the PSU.

The JPWR2 is for the CPU - there should be an 8-pin or 4+4-pin cable that goes into that port.

Ok, but somehow my PC managed to work with the two 6-pin + 2 pins hanging off in both the GPU and the JPWR2 before. Where can I purchase these 8-pin and 4+4 pin cables? Could you direct me to a link? I can't seem to find them on Newegg or Amazon.

This cable just arrived today and it wasn't compatible with my psu. It turns out it could only work for Silverstone- PSUs. I can't find the 4+4 pin ATX12v connector that's compatible for Rosewill PSUS anywhere. What should I do next? I don't want to throw away money by purchasing the PSU again just for that specific cable I need.

Your PSU should already have a 4+4 pin fixed to it, it can't be removed.
