4 HDDs stopped working at the same time, SSD working fine

First I had a system going with one SSD (with the OS on), and two HDDs. All are connected to the MB with SATA-cables, the SSD is connected to the PSU with a SATA-power cable, and the HDDs are connected to the PSU with a secondary SATA-power cable (which has two connections on it, allowing it to power both drives with one PSU-connection).

Today I was going to install two additional HDDs (one empty and one with another OS on it that I was planning to format), I had gotten myself a new PSU-cable that has four SATA-power connections on it. So I connected everything, SATA-cables from all HDDs to the MB, and now one PSU-cable powering the four HDDs, and one PSU-cable powering the SSD. The computer booted fine, but now I see in Windows that only the SSD is recognized. I restarted the computer, and went into the BIOS, and found that also there only the SSD is recognized, the computer isn't aware of the HDDs at all (and remember two of the HDDs have been working fine in this computer for a long time). Then I checked the HDDs while the computer was on, and none are making any noise, nor any vibrations.

I then tried to switch back to exactly the way it was before, with the old cable and only the two HDDs, but still only the SSD is working. I tried connecting my HDDs one by one into the power cable and sata-cable that the SSD uses, but still none are working.

So have really all of my HDDs died at the exact same time (presumably from the new power cable), or is there some way to at least get it back to the way it was before? As I heard no weird noises or anything, I doubt there is any physical damage to the drives, but I just can't for the life of me figure out why then the old setup is no longer working. I have also not found anyone else experiencing the same thing (several HDDs not working, even though they worked moments before). One of the old HDDs has a music and movie collection of almost 1TB, so I would be really grateful if someone helped me solve this problem. Thank you in advance if you do help me.

How sure are you that is it the PSU's fault? I can test the HDDs with a different PSU, but it will probably take me over a week to get access to one. Is there anything I can do in the meantime to test if it is the PSU or not? The one I currently have is a Chieftec Super Series 750W, with a GeForce 670 and an i7 4820k.

Well, I tried disconnecting everything, and just connecting one drive at a time (with the power cable that the SSD uses), so that the PSU then only needed to power one drive. Still the BIOS did not detect anything.

All the connections to the HDDs are like in this picture: http://www.sierra-cables.com/Cables/Images/SATA-B_DriveEnd.jpg (yellow-black-red-black-orange)

On the connection to the PSU I could not find a picture to confirm if it is wrong or not, but there they are:

black-black-orange
yellow-empty-red

Also the connector itself is white, if that helps in any way. It did not fit into the black parts of the PSU (where the cable with 2 connections fit), but it did fit in the red parts.

Edit: I can post pictures of the cables and the PSU later if that will help

I have now tried installing a different PSU, but still none of the HDDs are spinning. The SSD still works with the different PSU. If I have blown the protective diodes as popatim said, is there any way to save the disks?

Edit: Also I should add, that none of the discs have any visible burns/damage on their circuit boards.

Edit 2: I tried using the new cable to power up an old optical disk drive I had. The result is that the drive began to produce smoke. I of course quickly disconnected it, but this leads me to believe that this new cable has damaged all 4 HDDs. Though I cannot see any damage on the boards of the HDDs, so does anyone have any way for me to check where the damage has been done, and (if possible) fix the damage? If this is non-fixable damage, I'd also like to know, so I can begin buying myself some new HDDs.
