How do I find out how many amps my PC power supply really puts out?

Luckydevil:

What brand of amp is it? Depending on whether or not it actually puts out anywhere near 300watts... I would highly recomend not hooking this up to your pc power supply and buying a seperate ps for it.

Whoops! I was drinking when I posted and typed 12A when I meant to type 24A on 12V line.

This PC power supply is just for my LEDs and car amp.

On another tread about 2 weeks ago we figured out that a 300watt amp would draw about 25A and my LEDs would draw about 3A from the 5V line. Yet i was told that all amp makers over exaggerate the watts that their amps put out and so do the PC power supplies.

If I want to find out how many amps my amplifier draws I guess I could hook it up to a small stereo and the two 6x9s I am going to use and see what happens Yet I don't know how to measure the amps its drawing.

Isn't there another way?

Luckydevil:

Not all of the manufacturers overrate their amps, some even underrate them. All depends on the quality of the brand.

What size fuse does this amp have on it? The fuse size will be slightly more than the max amount of power that the amp will draw.

This means something.  This is important.

The amp is made by pyramid and is a 300watt amp/equalizer, model 808.  The cheapest I could find.

The 550watt PC power supply is made by Okia and is the cheapest I could find. Model okia550atx

The red power lead on the amp has a inline fuse in some kind of white palstic case. Should I open it and look at the fuse. I cant figure out ....I got it.

It says on 6A 32V on one end of the fuse.  The other side jsut has the name jasco.
