Electronics filter: What can I do to make a 24v PSU turn into a 18-19v PSU? It's 0.5A power supply which as far as I can tell is important to know when using, say a resistor to lower voltage. But how resistant should the resistor be? I've found information on how to tell a resistor's value, but not how it will actually effect a line's voltage or how to calculate it. Are there any good sites with this information? Also what will happen to the amount of amps the PSU supplies when I do change it to 18/19v?? Also, what can be done to increase the amperage of a power supply? What inside the circutry is actually dictating the amperage?

Here's a technical question. Will this motherboard work with a G3 (Mac) power supply? Gigabyte GA-6VTXD Also in the motherboard is an AMD Athlon 900Mhz. Is that fast? What's the comparison to Intel chips? I've never really understood the conversion. I thought it would be neat to use an old, unwanted G3 case for something like this. [more inside]
