Confused about SPEAKER, POWER_SW, H.H.D LED Connectors

Postby alnazli on Sat Apr 11, 2009 2:57 pm

i am currently building my system with Cosmos S

but i am not sure about the polarity these connectors:

SPEAKER Connector; Red wire is power, and Black wire is the ground?
POWER_SW Connector which is the poweron botton i think; Red wire is power, and Black is the ground?
H.H.D LED Connector which is the hardisk activity connector i think; Red wire is positive, and white wire is negative?

thank you

Switches don't give damn about polarity and with indicator LEDs cathode pin (minus) is generally the common colour you find from from cables of both LEDs.

This should help.
Note: Power Switch and Reset switch has no positive (+) or negative (-) so that means it should work anyway you connect on your motherboard. Now with HDD and Power Led you need to connect (+) with (+) on motherboard and (-) with (-). Simply connect Hdd Led and Power Led on to your board and turn on your computer if you don't see power led or hdd led just reverse the connectors. Simple.

Correct that attached graph. LEDs aren't any zeners which are used in reverse direction.

On the connector itself you will see either a triangle or a G, triangle = positive and G = negative. On switches like the POWER SW and the RESET SW its not an issue, but you do have to get it right on the Power LED and HD Led.
