Bulgin switch
I have a vandal LED switch, but need a 3 pin 3V power output for LED power, and MOBO only has 3 pin 5V, for case Power LED, how can i get the switch LED power?
Basic Electronic Gurus please chime in, but this sounds correct:

"Note: The LED runs on 3.0V DC. You will need a resistor in the line to power the LED from either your motherboard's 5V DC output or your Power Supply's 12V DC output. You can run the LED directly off of the motherboard's 3.3V LED headers without any resistor.
We were informed that the correct resistors for the switch's LED are the following:
12 V DC source: 420 ohms
5 V DC source: 70 ohms
[thanks to D. Huff for providing this data]
FrozenCPU.com cannot be held responsible if the LED is burnt-out from application of too much power. Please make sure your are outputting the correct power before connecting the LED."
I am not a professional in any subject! Do you have a multimeter to verify to correct voltage is available after placing the resistor?
