New Build Pin Connector Trouble

post #1 of 5
Thread Starter 
I am in the process of building my first HTPC. I am almost there but I am a bit confused. I have a Rosewill R379-M Case and a CIH61M V:1.0 MOBO.I am trying to connect the Front Panel Pin connectors and HD Audio pin connectors to my MOBO.

Here's whats on my MOBO:

F PANEL
1-2 HD LED
3-5-7 PW LED
12-14 RST
9-11 PWR SW
4-10 SPK

the PW LED is two seperate pins one with + and one with -

the pin diagram on the mobo looks like this:

Also the HD AUDIO pin diagram looks like this:

But the connector looks like this :

Thanks for the help.

Best bet would be to find a copy of the motherboards manual if possible. Otherwise buy a motherboard instead of trying to reuse one from a prebuilt.

I've always wondered, can you actually damage the mobo (or the front panel) if you connect the front pins incorrectly? Sometimes they aren't documented very well.

Not very likely. Even of you connect the reset switch leads to one of the LED connections on the motherboard, the board would most likely have short-circuit protection of you press the reset button.

Easiest solution is to start with the power lead and find out where it goes on the pins. It's a momentary switch so with no power running you can't short anything out... It just won't power on. After you have the power switch set find the reset pins... Usually it's back-to-back with the power pins. The LED leads will be last... If you have the +/- reversed then the LED wont light up... It also will not short.

I had the same problem: I'm replacing the Lenovo MB with a different one (had display troubles that I think are the fault of the PCIe buss). I found this, which is for the A60 MB but seems to match the CIH61M for all but the front panel header connector. Maybe it will help you.
