What is the voltage for hdd led?

[tankkid]

Does anyone know what the voltage is for the pins that you plug the hdd led connector into is? Thanks

The manual for my MB says mine is 3.3 v.

most I've heard about/used/changed work fine at 3.3V. Power LED is the same as well.

Be careful of the load rating of the LED. That is listed in mA (milliAmps). I wouldn't recommend throwing a 30mA+ LED onto a default HDD LED pin. Most are current limited at 20mA max, if that. Any more could burn a trace or fuse (if its fused at all).
