How many volts is a LED?

[LegendBreath]

Hi,
I wanted to know how many volts LED have? And, how many volts that the motherboard give to the power LED and how many volts the powersupply give to a hard drive

Thanks

I think you mean watts. There is only a 3.3, 5, and 12 volt rails on any and all powersupplies. I belive LED's run on the 3.3 or 5 volt rails, and the hard drive uses the 5 and 12. As for watts, LED's use almost none. Between 10 and 50 milliwatts.

So... if I want to plug LEDs directly on my power supply I will use the floppy connector?

LED's come in varying degrees of what they can handle in voltages and wattages.
