These quick connect adapters make life easy. Used to have to slide each one of these small wires on to the pins and it was not easy with little space to work. Now each connect goes on to the adapter and the adapter slides on the pins in one step.
Q connector assembled and ready for the motherboard. Everything that is wired to the qconnect are from the front panel as in the USB, headphones, mic, power , reset, and led's.
Installed one video card for now. I will get the system running fully before installing the remaining cards. These cards need no additional power from the p/s. They get powered from the board. The cards are small and give off little heat. This will help also to keep the case quieter as the video card fans are very small. This also frees up more space in the case , again for good airflow due to reduced cables and smaller cards. Important: not a thing wrong with larger, better quality video cards. The case can still easily be cooled. I just simply chose this way.
