Why does the PCIe power adapter have two plugs at the end that plugs into the power supply?
Most newer power supplies come with a dedicated 6 pin PCIe power connecter. If your power supply does not have one you must use the PCIe power adapter (shown below) and connect both 4 pin Molex power connections to your power supply. This will ensure a reliable flow of power to your graphics card and maintain system stability.
