Re: Computer Power Supply and Turnout Problems
The problem may be that it is not providing power because there is not sufficient minimum draw on the 5 volt lines. Some power supplies for PC's require a minimum current draw on the 5 volt lines for it to kick in to provide all the other voltages. You can check the manual, probably on line, for what that number is. I have found that 1 amp usually works o.k. For yours, it may be less. so do check the manual, if you can find one.
