Connecting PSU to other parts -- question

  1. I've just finished installing all the parts and am trying to connect all the parts to/from the motherboard and PSU. On my motherboard manual it says that there is a set of 9 pins that handles a bunch of things like power switch reset switch HDLED etc.

    There is only 1 pin reserved for power switch and reset button. The wires coming from the case are 2 pins though. Is this common? Which pin out of the two do I plug in? Beside both the power and reset pins there is a pin called GND. Is this for use with the power and reset switch? If so, how do I know which pin goes where for these? On the back of the Power and Reset cables it has a G on one pin, and an arrow to an S on the other.


    Edit: Also, I've purchased an aftermarket CPU cooler - the coolermaster tx3 master tx3

    Is it possible for me to attach the fan that came with my i5 2500k processor onto this aftermarket CPU? I noticed there was room for a fan on each side of the heat sink.

    Connect both the power switch pin and one of the two GND (ground) pins you mentioned earlier to your 2 pin power switch case connection.
    Direction is unimportant for power switch and reset. But G is Gnd.

    It is for hard drive led though. worse case scenario is your hd light will be off when its on and vice versa :)

    Actually the worst case is the hdd light won't work. They must be plugged in the correct way because the LED is a Light Emitting Diode. Diodes only allow current in 1 direction. So hook it up backwards, no light. Hook it up correctly, light.

    Last 4 things that I don't know where to plugin...
    I tried to take pictures but the picture quality was not very good...

    One is a media reader for camera cards phone cards etc. It has 4 pins. 3 are grouped together and 1 is seperate. I don't know if my motherboard even supports this.

    One is coming from the case - so I assume it's compatible. It's 2x10 with 1 pin in the corner missing so 19 pins. I think it's a usb 3.0 cable

    The last two are somewhat similar. One is bulky with holes for two pins and says "wst" onn it. The other is bulky and has 2 pins and a hole for 1 pin and comes from a case fan. Images here:

    Thanks a lot. Really appreciate help, I am so close and am so excited to get this going!

    The media reader, what are the pins labeled as? If its a card reader it should go into a USB connection (really hard to tell from your pics)

    The second is a 20 pin USB cable

    The third terrible picture :p I believe is showing an Led control connection for fans that support it so you can adjust the brightness or on/off function of the LED's (not all fans support this) The other is fan pwr.

    Just a guess from the pics.

    Yup, the media reader plugged into USB. Turns out my motherboard does not support the 20 pin USB cable, so I can't use the 2 front USB 3.0 ports (2 in back so not a problem).

    The last image was case connectors as you said for controlling fan LED's.

    The 3rd image I believe is for my front microphone plug. The front headset works fine but not the mic input. This is a problem for me because I want to have my speakers plugged into the back and headset and mic plugged into the front. I don't see any connector for this on my motherboard.

    Is there an adapter for this? I have this motherboard:

    I'd just like to say that I'm still searching for an answer to this question :)
