I saw a post on Reddit pertaining to the 3000 series cards saying not to daisy chain your power cables. Obviously based on the title I don't have a 3000 card. I have a 2070 Super, and for about a year and a half I have used a single power cable on it. Is that ok? I don't have any problems with stability at all or running games, but I don't want to start a fire or something. I don't have another power cable right now. My PSU is a Corsair RM (2019) 650 W 80+ Gold Certified, if it helps.
