[Earth351]

Im trying to put some RGB leds in my pc. I did not work so i tried to test if there was coming any 12v from my psu to the molex and i got nothing and then i tried 6v and that 1 got power but my rgbs need 12v to work

im using 3m rgb strip / 90 rgbs

my rgb controller specs:
model: MY302
Input: DC 12v
output: DC 12v16.8W

How did you tested it? if you're using a voltmeter, the negative probe (gnd) goes in the black cables (gnd) and the positive probe goes in the yellow cables.

Do you have another molex? If so you can use one of these.

Was the psu on? you can disconnect the psu from the motherboard and put a jumper wire between a green wire and any black wire, that will jumpstart the psu, and you'll be able to check it without turning on your pc.
