System panel Connection missing 4 pin

  lexus2 13:04 07 Dec 2008

On building my pc i hit this problem, on my 1st boot I crossed my fingers and awaited the beep/beeps. Nothing happened on looking at my manual. it states a 4pin connection is needed, to hear the beeps. But I have a 3 pin connection and a 2 pin connection the other 3 connections are seated in the panel as shown in the photo so I know there correct. But what do I do to get around this problem I tried reversing the 3 pin connection oh by the way these are (power led 3 pin) and (hdd2 connection 2 pin)
So can anyone advise me as what to do with this problem.

Many thanks in advance

Oh my case is an Antec P180
and my mobo is a ASUS P5K Premium

Are you talking about the speaker connector? If so pins Speaker 1 and 4 on the Q-Connector are used. The Power and Hard Drive connectors aren't needed to boot, they just show the activity LEDs.

Does your case actually have a speaker? The case manual doesn't mention one.

Hello I am Spartacus

I have acquired 4pin connection with fan and I'm pleased to say the pc started with a single beep.
Thanks for all your help anyway. It was my second choice of action.

Best wishes and have a merry xmas
