No. I don't think so. I'm not going to open my case to show you. I think you need to RTFM, sir. You didn't answer my question, either. This here Mexican GEEK can't help you if you don't help me help you. Help me... help YOU... help ME... help YOU. Spoiler
He means the 8 pin cable on the motherboard. Most intel boards will have the 24 pin power connector as well as another 8 pin that needs to be plugged in. Check your power supply for that one.
Yeah, the motherboard has two cords that connect to it, the long 24 pin and the "square" 8 pin. The 8 pin cord is usually the one missed.
