Atx computer powersupply Wireing schematic

[jleaman]

Im looking for a schematic to tell me the pinouts to turn on a atx powersupply and also to load it i remember reading on this form that you have to put a load on the 5v side to make the power supply put out its full curent.. ( some one was using one for a car amp and that is where i read it..

Can any one help me please..

Try this ...

This one mentions something about a load on the 5V buss:

I'm not sure, though, if you can take the spec for the load for a particular model, and assume it applies to a different model.

Not exactly sure as I don't have one in front of me.

But I think the green wire.. should be like 4th from the left on one of the sides.. short it with ground. With my supply it'll only work by shorting to a specific ground that is located very close to the green wire. don't remember which. just try all of them.

You have two html files inside. Should provide enough info.

The link that I posted turns on the power supply.

All power supplies comes with a manual that shows the pin output of all the power connector. The power supplies that came with the case does not have a manual for the power supply.

JasonL, why are you going to power with computer power supplies. Its best to buy a linear power supply for audio use. Also 18 gauge or gage is not big enough for high current devices. There is too much a voltage drop for amplifiers.
