Having trouble figuring out how to plug the power header in

[ghastaphish]

Hi all, I'm freaking out about the power header and was wondering if someone could tell me how to find out which end of the header is the ground and which is positive. The power header cable has a white wire and a red wire leading into it. My case is a HAF 912 and my motherboard is a asrock micro atx. please help!

read the instruction manual for your mobo and it should say on the head of the cable, the block covering

Are you talking about the power switch? It doesn't matter which way it goes. All it does is complete the circuit when you press it. You could even do it with a screwdriver or paperclip.

Yeah it's one of the hardest things to do on a build. The instruction manual explains how to do this, but it can take effort to get working.

Cases will generally have four 2 pin headers, power and rest switches, power LED, and drive LED.

The switches are non-polarized. It makes no difference which way they are plugged into the motherboard.

The LED's are polarized. Generally the white lead is the "-" side. However, if one of them does not work, simply reverse the connection. You cannot damage a case LED by plugging it in backwards.

Just consider the wire that isn't black the + or #.
