2PIN CONNECTORS HELP

[sikanx]

building a computer for the first time today..

i am going to connect the power led, hdd led to my MOBO,
but i heard these 2pin connectors are polar, and the wrong direction will damage the mobo.
how do i determine which pin is the positive/negetive
/?

Yes, you are correct, the power LED, HDD LED and Speaker are polarity required. Normally, the white/black color is the negaitive (-) I wouldn't say it will damage the motherboard. The LED just wont light up. If they don't, then you know you had them plugged in the wrong way. Just remove it again and plug it in the other way. I like to take a picture of it once I got all the connections right. The next time, you will know how they are plugged in.

Only the LED care, and they just simply won't light up. They will not break, or do any funny business.

Switches just close the curcuit, nothing fancy.

It's not a big deal if you mess that step up, however looking at my mobo right now, I can see that the text on the pins are downwards toward the bottom of my case.

The ground/negative wire color is the common color, typically.
