Hey i just got an account here and i am needing some help with a power supply. First thing is, Im not actually using this power supply in a computer. I am putting a car audio system in my home and im using the power supply to power the amplifier that is in turn powering the subwoofer. I have a dell nps-305bb c and all i need to know is which wire (color) is the 12v power wire. any and all help would be greatly appreciated. thanks

 

p.s. it has a 24 pin connector but the power supplys ive used in the past have a yellow wire that is the 12v power but this one does not have a yellow wire on the 24 pin.

 I have to ask.  Couldn't you use a voltmeter to find out?


Everyone with a computer should back his system up to an external hard drive regularly.  :thumbsup:

You can short the green and black wire on the 24pin connector that will let you turn on the PSU without a motherboard.

There is  an adapter that does the same thing and eliminates the paperclip.

 

Once the PSU is running you get 12volts from the yellow wire on the Molex connectors.
