Hard Drives not working after installing new GPU? Possibly broke?

Hello, recently I have installed a new R9 graphics cards to my desktop.
I had to move the cables around quite a bit to get it to fit and when I turned it on at first, I smelled some sort of firey/smoke, but did not see any magic smoke coming from it. At first I thought it was the GPU, but then I noticed that two of my three hard drives are not listed at a boot device during the BIOS.

I tried rearranging the cables and such, and eventually went as far to replace a known-working hard drive with one which did work. So the cables were fine, it was just the two hard drives that somehow busted? The good thing of this though, is that those two hard drives were secondary hard drives and my main hard drive is still intact and working well, since as I'm writing this.

Another thing, the two hard drives were connected with extension power-SATA cables via molex extension.
I assume something might have short-circuited the molex connectors were slightly loose, but I don't understand how that happened.

Since I did not see any magic smoke and the HDD's look fine, nothing burnt visible on them, is it possible to fix them easily with ordering a few small components?

Yeah I tried both HDD's with a power SATA cable, and I did not feel any movement within it.

No warranty, but I did find, in the green WD HDD that a component on the board was fried, so I think replacing that should fix it. For the smaller HDD, I still have yet to check.
