Burn out power connector

Miscellaneous Forums/General Discussion/Burn out power connector

Hey, i switched on my computer today and got an error message saying my ATI Radeon's additional power connector isn't connected, so upon closer inspection, i pulled it out and noticed one of the four pins had burnt out.

Is this a sign of something more serious, or just normal? It's probably plugged in there for about a year or two, and the computer is very rarely left on for longer than 7 hours per day.
