Issues with connecting my graphics card to power supply

[Igloogreenhouse]

Hi, new to forums, seems like you guys are nice so...
I purchaced components from this guide.
https://www.techspot.com/guides/187-buying-guide-200908/page3.html
Everything was great as i started assembling my pc, but as i looked to connect my ATI Radeon HD 4770 to my OCZ OCZ500MXSP power supply reccomended in the build, I saw the free chord I had for my power supply had 8 pins, but my card was a 6 pin slot. I checked the case my card came with, it had a lot of adapters to attach to the 6 pin slot on the graphics card, but none of them could get me connected to my power supply.
I know im missing something here, because these components were reccomended from the same build from TechSpot. Anyone got an answer.
Thanks.

There is an 8 pin connector for motherboards with 8 pin CPU power connectors. It is not for PCI-E cards. However, according to Newegg's listed specifications, you should have two labeled PCI-E connectors, one with 6 pins and one with 6 plus 2 pins. The 6+2 pins might look like 8 pins but it splits into a 6 and 2 pin so you can use just the 6 pin connector if you need to. Use one of those for your graphics card.
