I purchased a ready-made system with a 650 gtx and a 550 watt power supply about three years ago. Recently, I swapped the 650 for a 3060 and also upgraded the power supply to a 650 watt unit. The issue started when my old 550 watt PSU had a 4-pin ATX connector and everything functioned properly. Now, with the new power supply, my monitors refuse to receive any signal when powered on. I’ve inspected all cables and confirmed they’re securely connected; everything seems to be in place. Do I really need that 4-pin ATX port? Please advise and let me know—I’ll need to clean it up soon.
