Which voltage does the Power-On/Status and the HDD activity LED connectors of a motherboard deliver?

The only thing I could find that mentioned a voltage was here and it specified 3.3V

Thanks for coming by! My name is Michael 'TeX' Hex, living in Speyer (Germany), close to France. I don't think of myself as a software- or system architect, neither as a software artist, but as a Transmogrifier. That's because in IT it's all about transmogrifying data from A to B, no matter what you do. In case you are interested what I do, visit my homepage or my blog.

The case I want to use does not have an option to connect the power or HDD activity LED. Therefore I would like to use some 3V LEDs I already own.

However, since they are only for 3V, I would like to know which voltage does the power on/status and the HDD activity LED connector deliver and if I can use them.

The motherboard in question is a Gigabyte GA-Z68XP-UD3-iSSD, but the manual does not provide any information about this topic.

Thanks. A friend of mine just sent me this link and they say it would be 6V? tomshardware.co.uk/forum/105629-12-power-voltage

This one says 3.3V overclock.net/computer-peripherals/… I guess the worst that will happen is your LED will go pop it won't kill the PC

Poor mens test then? If it smells = Does not work. JK, I will test it. Thanks for the fast answer!
