So I just got my new i7 7700k fitted today along with my gtx 960 EVGA I got the MSI Z270 Gaming pro carbon and I have a 650 watt PSU, everything is fitted but for some reason the mystic lights that are shown on the image dont light up when I turn my PC on, I think it may be because I have not got my ram put in yet because its still in the mail, is this possibly why its not lighting my motherboard up?
