I used to have a MSI k7t turbo 2 mobo and it, as well as other mobos of its time, had a spot for the 12v power supply lead to provide the extra juice for the faster cpus. I got my new board, a MSI KT3V and it has no spot for this 12v connection. Is this a cheap board or is it no longer neseccary and none of the new boards have it?
