Is this PSU Normal?

Ok guys, i think i received a bad power supply, I am not exactly sure. Here is my problem though. On the PCI-E connectors, i have an 8 pin, and a 6+2 pin. On the 8 pin connectors, there is one wire missing on one of the holes. 2 wires are going into one hole.. Actually, ill just post pics.

(As you see, 2 wires are going into one hole, instead of the extra wire going into the blank hole.)

(You can see here, that, one hole has nothing in it, other than air.)

(Here, you can see that the power supply needs 8 pins.)

I need 8 pins on each side either, i cant reverse them. My GPU is 8 pin, and my PSU needs 8 pin. What do i do? Is this a failed power supply? Or is it supposed to be like this? If so, what side do I plug into my PSU, and what side do i plug into my GPU? I also want to say that, I actually have 2 of these cables, too, just incase that matters. My GPU is also an r9 280x. (Sapphire Dual-X).
So, is this a bad PSU? Thanks in advanced!

They can wire it however they want on their end, just make sure that the end that goes into the graphics card is right. There are some companies that will double up the pin because all the 8 pin PCI-E connector is carrying is 3 +12 V lines, and 5 ground lines, but since you have more grounds than hots you don't necessarily need to run each one to its own pin(especially on their size), this will show you how the PCI-E on the GPU end should be set up

If it is just a ground line doubled up that won't be a problem and may be intentional on their part(you don't accidentally crimp two wires, that just doesn't happen, its too damn hard), if they screwed with one of the...

If it is just a ground line doubled up that won't be a problem and may be intentional on their part(you don't accidentally crimp two wires, that just doesn't happen, its too damn hard), if they screwed with one of the 12V lines instead(because they decided not to color code :/ ) then that would be problematic.

The downside to the flat cables is they are way harder to identify what voltage each pin is.

I don't get it. Im a novice when it comes to computer building. I am only partially good at programming. What is exactly what i have to do? My PSU is a Rosewill Hive 650w. I forgot to mention that. If i just leave it how it is, what side of the cable do i plug in to my PSU? Also, the other side of the cable, is a 6+2 pin. That 6+2 pin is completely fine. No missing holes in the 6+2 one.

Ok, problem solved. I guess its supposed to be like that. I checked newegg's videos, sponsoring my Power Supply, and on their video, they showed the PCI-E connectors. I found out that they have an empty hole too. So, i guess its originally like that. So, i guess i can start building my PC tomorrow!
