CPU power connector doesn't fit.

Hi, so I've recently purchased all of my parts for my PC and I began to build it when I realised that my PSU cables do not fit in to my motherboard's CPU socket.

The motherboard socket looks like this:

And the PSU cable looks like this:

Sorry if these are bad pictures, I just found them on the internet.
Also, sorry if this is a noob question, it is my first build.

See how only one of the 2*4 pin connectors fits and the other doesn't? Help would be appreciated.

Can you give us the model of the PSU, motherboard and CPU?

If your CPU is a lower tier, you can run it with only 1 connector. I have run a Pentium G or and I3 with only 1 x 4pi plugged in. But when I put an I7 - just for the sake of it, I tried, and it didn't run - the I7 required both of them to be plugged.

I'm using a M5A97 EVO 2.0 mobo and an AMD FX-8350.

Turns out I'm an idiot, even though the cable has a rounded one rather than a square one it still fits...
