There is a connector on my motherboard that is labeled in the manual as PCIe-PWR1. When I built my computer about a month ago I didn't plug anything into it because I remember hearing that you only need to use it if you need a lot of power in your PCIe lanes. I have been using the computer with an i5 4690k and GTX 780 for a month and haven't had any problems but should I plug it in to even out the power?
