Hello,

I am building a computer with/for my son and have hit a wall.

We have an Nvidia Geoforce GTX 660 GPU and a Corsair CX600M power supply. The GPU comes with a connecting cable that has one end with 6 pins that plugs into the GPU and another end with two male 3 pin connections (flat, have room for four pins but only three are present).

The power supply has several modular cables. One has a 6 pin connection on one end that looks to plug into the power supply and four female four pin connections that the GPU male connections will fit into. The last male connection has an extra plug that does not appear to fit anything on the motherboard or the GPU.

Do I need to plug in both ends of the cable that attaches to the GPU to the power supply cable?

If so, does it matter which two connections I choose?

Finally, do I need to do anything with the extra connector at the end of the power supply connections?

Thanks. This is our first build and I am finding the manufacture instructions a bit confusing and have not found anything on the web that addresses the power supply connections.

You don't need to use any cabling supplied with the gpu.
Just use the 6pin pci-e cable from the psu to gpu.
The cables are labeled with that psu.
That psu includes 2 6+2pci-e gpu power connectors.
Just use one and leave the extra 2pin part dangling(it's included for some gpu's that have 8pin socket)

Thanks for your reply, but none of the cables that came with the PSU were labeled ... they were just tied up with twisty ties and in a clear plastic bag. The PSU was new.
