Power switch + or - ?

Solution
I always assume ground. Although I could be super wrong. But I do know that the power switch really doesn't care either way. It's a momentary switch that just bridges the connections when it is pressed. You can actually turn on the PC by connecting the two pins with the head of a screw driver.
