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.

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

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

This one says 3.3V http://www.overclock.net/computer-peripherals/717451-power-led-hdd-light-voltage-answer.html I guess the worst that will happen is your LED will go pop it won't kill the PC

Good luck with it. – Col – 2011-08-17T17:46:02.957
1Do you have a multimeter? Plug it in and see what the DC voltage is directly. They can be had pretty cheaply. It'll help to have a normal load on the circuit; plug a standard case LED into there at the same time and put the multimeter in parallel. – Chris Smith – 2011-08-17T17:31:24.563
@Chris Smith: No, I'm sorry I have no multimeter - yet. But I buy one with the next PC ;) – Tex Hex – 2011-08-17T17:33:14.540
