MSI N260 GTX problem

[TechBook]

I bought the components for my PC, I have a MSI Motherboard PT 890, I bought a N260 GTX and since I have more sound, I was told about a cable to plug into the card video that goes to the motherboard or sound, but I did not get . Other idea? : so (I've formatted several times, installed the appropriate drivers, and those that I use after each formatting)

You absolutely must have this cable to plug into your graphics card (cable from the power supply). If this is not the case: you must change your power supply.

I changed my food at the same time, and I have already connected the two cables from the power supply going to the video, but right next to my output on my video card, along with two large cables from the power supply, and that is that I must plug into the motherboard or sound card at first. But I have not had with the box.

If you want the sound card on the motherboard must disable the sound of the n260. The sound on the graphics card is usually if you use the hdmi for watching on a HD tv.
