Modded PC power supply for charging

[BrianG]

You are correct, but I did make a note of that in step 2. ;) I have also had to add a loading resistor to an older PS as you explained, but I felt that choosing the appropriate resistor size to provide enough load was beyond a "simple mod" for some people. The resistor has to have an appropriate resistance value along with the right power rating and I figured the formulas would be too much. Plus, it might be a pain to figure out which supply rail needs this load. I have seen supplies that need only the 3.3v line for the rest of the supplies (5v and 12v) to work. However, I can go into that if anyone thinks it will be helpful.
