Another reported 16-pin connector melt has surfaced in a short period, and this case reportedly happened while the PC was completely idle.
According to the owner, no third-party adapters or splitters were used. The graphics card reportedly ran factory VBIOS firmware, and the cable was reportedly a native 12V-2x6 connected to an ATX 3.1-compliant ASRock PG-1600G power supply.
I’m not diagnosing this specific unit or claiming a proven technical cause. The practical lesson is that a 16-pin connector melted at idle is not purely a load or overclocking problem. Contact resistance and how well the connector is seated can matter on their own, so idle operation is no guarantee against trouble.
For PC builders and repair technicians, 12V-2x6 connector inspection belongs in routine high-power GPU service. Check for discoloration, deformation, or a loose fit, especially when using an ATX 3.1 cable.
