# Powering a double din car radio off desktop PSU?

I've got a double din car radio I'd like to be able to use/test in my house so I'm trying to figure out the best way to power it. Someone on another forum suggested a desktop PSU, but for the technical electrical questions I decided to come to a forum dedicated to this kind of thing...

The DD radio is powered off of a 12Vdc source (according to the manual). The manual doesn't mention amps at all except for the fact that in the back of the radio these a 10A ATM fuse. So I'm assuming the fuse is there to protect the entirety of radio it self.

My PSU supposedly has some cables that do a max output of +12V/19A. (I included a pic of the PSU). That should be safe to run off of, correct? I realize the amps are to high but the fuse should protect the radio.

My next question, is figuring out which wires are the +12V/19A ones...According to wikipedia, http://en.wikipedia.org/wiki/Power_supply_unit_(computer), the +12 are either of the yellow ones, and the ground are black. Those should be the only 2 wires I need.

Thanks again
