An old computer power supply with 12 volt output.
Wonder if that would drive a CB mobile, or a CB
walkie? Makes me wonder if I could wire a lighter
socket to an old computer power supply and have a
couple amps of 12 volt DC?
I don't see why not. Twelve volts it twelve volts. I wouldn't think a CB
radio would require any super regulation and computer power supplies are
pretty clean.
Anyone know how much 12 volt DC a power supply provides?
They usually have a label on them giving their output. Here's an example

But, even a super cheap one should be plenty to run a CB radio.
Just remember, you need a resistive load on the 12 volt line before
you get ANY output on most supplies.
The 250 watt AT supply I have sitting on the bench puts out 11 amps
on the +12 side.

that would be the FIVE VOLT line.That's what most PC supplies regulate on.
You are correct. Minimum 500ma load on the +5 required for stable
voltage output on +12. I always just threw an old hard drive on when
checking out a power supply (or trying to test a motherboard - MB
alone in about 99% of cases was not enough load to start, and if it
was, it was not enough load to regulate properly and half the time you
didn;t get the required "power good" signal.
