ASUS P5AD2 Deluxe no beep & system failure cpu test failed

My Little Tale about Asus P5AD2 Motherboard upgrade !!

I bought a ASUS P5AD2 Deluxe 925X Motherboard yeseterday which was an
upgrade for my P3...right i haven't assembled anything for a while.
Anyhow, After the assembling I was having problems with no beeping
sound when the motherboard was turned on.

ASUS P5AD2 Deluxe 925X
1 Gig DDR2
P4 3.0 Intel Processor
120 Gig WD HD
480W PSU Antec (20 pin) it works !!

Finally i figured i need to plug speakers with sound on the moterboard.
Voice Woke me-- Error: System Failed CPU Test Failure

I went around on the internet i was not able to find anything. I
thought I did everything correctly. After 1 day of research I was told
there is a extra power connection from PSU to the motherboard for the
CPU. That was connected it powered up with no issues.
