As you know, the new 12VHPWR power connector requires very close contact with the graphics card power connector. Some users overlook this point when installing a graphics accelerator. In this case, the power cable connector and sometimes the power connector of the graphics card itself can melt under load – such cases are not uncommon. MSI found a simple but effective way to avoid this.
The company has developed a dual color 12+4 pin 12VHPWR power cable connector. One half is yellow, the other black. The idea behind this is that if the user still sees the yellow part of the connector when connecting the connector to the power supply or graphics card connector, it means that it is installed incorrectly. In this case it is necessary to insert the power plug deeper until only the black part of it is visible.
The manufacturer demonstrated the solution at Computex. Below are two photos. The first one has the power plug correctly plugged in, the second has it plugged in incorrectly as its yellow part is visible.
The demonstration was performed with an MSI MAG A850GL ATX 3.0 power supply. The power supply model doesn’t matter, since all of MSI’s new ATX 3.0 power supplies have compatible 12VHPWR power cables, and the cables themselves are double-ended, meaning they have the same connectors on both ends.
It is pointed out that other manufacturers can easily implement this idea with cables and power supplies. No changes to the design of the connector itself are required.
