MSI Z77a-GD55 no post

Hi guys,
I just finished building my new system and when i press start.... i get no post, no beeps.
The phase LED lights stays only on LED1, i dont know what that means, i read the manual and it says something about no reliable power flow to processor.

i tried posting with just the cpu on (i5 3570k) and still i get nothing.

any suggestion on what i can do next?

Thanks in advance all help appreciated.

  1. Make sure both power connectors to the mb are pluged in.. should be one in upper left or on left for cpu and one on right thats a bit bigger..
  2. yes the 8pin and the 24pin are plugged in... i got power all the fans starts but it doesnt post
  3. UPDATE!!!
    It ended up being a faulty Mobo so i had that replace and its up and running.

    Thanks for the help and advice
