"The Ultra company has come up with a great idea that helps with the management of the power wires inside of the case. This idea is called the Ultra Power Bar that is located on the motherboard tray. The Ultra Power bar is a patented idea (Patent Number 7,133,293) by Ultra that allows the user to plug in two 4-pin power connectors and two 8-pin power connectors from the power supply, and gives you the option to have a total of four 4-pin and two 8-pin power ports at the other end. Ultra has packaged a bunch of power cables that can be plugged into one of the 4-pin or 8-pin power outputs on the Power Bar."
