Title: GA-790XTA-UD4: internal speaker voltage?
Post by: eromero on October 11, 2010, 07:12:50 am

Hi!
 I want to buy a small speaker (buzzer) for my motherboard and so would hear the boot  beep codes. To use the correct buzzer, I need to know the voltage of the front panel speaker headers. Could be possible to use a 3VDC mini buzzer?
Thanks in advance.

Hi this is te first time I have been asked what voltage the front panel speaker connection produces. The normal buzzer fitted is a piezo electric one and although I am not 100% sure I would have expected it to be 5v as most semiconductors run at that voltage. You can get a compatible one at any computer store and I am sure most electronic shops for a matter of pence.

A PC speaker is 5 VDC (volts of direct current), positive voltage.
