Received a new PSU today and discovered something interesting on my motherboard. I own a gigabyte lmt 3 usb, (this is hard to explain, so bear with me) there is text on my mother board that says "ATX_12V" and next to it a port for either 4 or 8 pins. Previously, there was only 4 pins plugged in here, however my pay has arrived with an 8 pin connector for this slot. I'd post an image, but I'm not sure how to do it.

Really sorry about the bad explanation, answer would be appreciated.
