Graphics cards shouldn't melt. Some have. That's the reason for a device such as this one from Ampinel, which keeps a graphics card's power demands in check across the compact 12VHPWR and 12V-2X6 connectors.
The Ampinel from aqua computer is a small device that connects to a graphics card's power connector. It's compatible with any GPU using the modern 16-pin connector, ie most of the RTX 40- and 50-series cards. It works by monitoring the current and voltage being delivered to a graphics card, though unlike other devices that do much the same thing, it actively distributes load across the connector to ensure no single pin is overloaded.
