A PC gamer has developed a free application called "12VHPWR Guard" to prevent potential power connector failures on high-end NVIDIA graphics cards like the RTX 5080 and RTX 5090. The tool monitors per-pin power draw and automatically shuts down the system if it exceeds a configurable threshold, such as 9.5A for 15 seconds, to mitigate the risk of connector melting. This safeguard is particularly relevant given the high cost of these GPUs and documented issues with the reliability of their power connectors. AI
