I want to convert a pc power supply to power my DFRduino mega 2560, but is the 12 volt rail is too high for the arduino as the upper limit it is rated to is 12V. If it is could I use a circuit like the following to reduce the voltage?http://powersupply88.com/simple-12-volt-to-9-volt-dc-dc-converter.html
I'm assuming as a power supply is used in a pc all its outputs would be regulated, is that right?
Last question: The 12volt rail is rated as having an 8amp output is that the maximum it can output?
My arduino is arriving tomorrow so the last thing I want to do is blow it on its first use
