I htought it might be interestign and slightly challenging to build a PSU i am open for any ideas pointers or good websites that will ehlp me do thsi all the better thnx for your help
 
Hey my skill level is not to high in actually constructing anyhting, i mena i am good witht hat kinda stuff though i really have never put anyhting of this skill level together

on money issues io got about 100+ to spend
 
This link ATX Form FActor provides the specification for an ATX PSU. As you?ll note there?s a lot to consider re: design. A power supply with a single voltage output is one thing, but a supply with several well-regulated outputs is another. You will also have to provide safety circuitry to shut down with overload, no load, and over-temperature. You will need to provide an always-present standby voltage and a means to turn it on via pins 14 and 15 in the standard motherboard connector. Components required are not likely to be found locally. Making it compact enough to fit in your PC?s case is going to be difficult. You will need a means to test it under load, as it seems that your PC cost a good sum of money. I don?t think it makes a good test bed for a first try so to speak.

I'm actually designing and building a prototype power supply currently, although it is for a car amplifier that steps 14V up to +-50V.

I wouldn't recommend playing around with this stuff unless you KNOW at least basic electronics and theory.

Many things can go wrong, from blowing a fuse to venting capacitors (not nice at all), flaming resistors, or melted wires.

The heart of the power supply will be in the transformer, the switching frequency, and the pwm controller you decide to use.
