There are a few different ways to wire a Gigabyte motherboard, but one of the most common methods is to use the 24-pin ATX power connector. This connector supplies power to the motherboard, and it's usually located at the top-left corner of the board. Other connectors that you may need to connect include the 4-pin CPU power connector, which provides power to the processor, and the 8-pin EPS12V connector, which supplies power to various other components on the motherboard. There are also several SATA connectors (usually six) for connecting hard drives and optical drives, as well as a number of USB headers and audio jacks.
