Hi People!!
this is my first post here. I am also not an expert so please be patient!!!
I would like to feed several led strips with a computer power supply. I got myself a Compaq pdp-123p, and I have different led strips, some that require 12 Volts and some others 5 Volts.
I turned on the power supply using the procedure illustrated here (http://www.instructables.com/id/How-to-power-up-an-ATX-Power-Supply-without-a-PC/) and I measured the voltage coming from the power supply to be sure everything works ok. What I got from the cabels that are supposed to deliver 12 Volts, was 9.05 Volts, and from the ones that deliver 5 Volts, 3.98 Volts.
Is this normal?
Am I safe to connect the led strips anyway?
And why do I obtain this values and not 5 or 12 Volts?
thanks in advance!!!!
