The 6 pin you have is for the video card NOT the 8 pin on the motherboard and should not be used there. That is the CPU power supply and you will need either a 4 pin or a 8 pin connector depending on what CPU you have. Most power supplies these days have a 2 x 4 pin connector that can be clipped together to accommodate a separate 8 pin and 4 pin. If your CPU only requires a 4 pin, then the 4 pin connects to one half the 8 pin connector-usually the top. If your CPU requires an 8 pin you have to have a 8 pin connector.
Most motherboards will accommodate a wide variety of cpus which is why they put a 8 pin in even if it may not be required. So check your CPU power requirements before deciding what power connector to use. May just be wise to just use an 8 pin, it won't hurt anything even if the CPU only needs a 4 pin. And again, most PSUs these days will accommodate both, or at the very least have an 8 pin, but double check the specs before ordering.
