PSU help.

Hello Escapist, I recently bought a PSU and Graphics card, largely installed it but I'm curious about one tiny thing: the Graphics card needs a 6 pin and a 8 pin plug thingie, the PSU came with two eight pins, the long one that goes in the motherboard and one labelled "CPU".

I've put the CPU one in the motherboard as that seemed logical, but the Graphics as said needs an eight, and where I've put the CPU labelled wire a four pin previously sat, so my question is, can the CPU labelled pin safely go into the graphics card without blowing it up or whatever happens, and simply use a four pin for, well, where one used to be?

In case it helps and/or changes the answer, the graphics card is a geforce GTX 670 and the PSU is a Corsair builder series CX750 (at least that's what the box said). The motherboard, I THINK, is an asus model, but I'm entirely unsure.

Alternatively can the graphics card simply run with just the six pin.

The graphics card won't run without all of the power sources connected. You said you have two 8 pin connectors on your PSU? One goes to the mobo and one goes to the graphics card. The 8 pin plugs are backwards compatible with the 4 pin plugs and often split into two so if your mobo only has the 4 pin connector using half of the 8 is fine.

I don't think I explained myself properly, not so good at explaining, I essentially meant I only have one 8 pin that would fit in the GPU's 8 pin slot but that's the one labelled CPU, but it's irrelevant since I sorted it using a 6+2 pin. Thanks for the help all the same.
