How much voltage is sent to the power LED and HDD activity LED leads on the motherboard. I think it is somewhere from like 3 to 5 volts, but I would like confirmation, I have a sweet mod coming up, and it involves an HDD lead triggered relay, so I need to know how low of a control voltage to look for.

Did you try measuring it with a volt meter?

Im sure you have one, if you are planning any mods.
