robbie no6 Posted January 20, 2007 Share Posted January 20, 2007 Hi I was wondering how easy it would be to set up a desktop pc to run from a 12v car battery. If a desktop power supply is 12v, 5v & 3.3v could it be as sinple as getting some chunky resistors in line to drop the voltage? To utilise ohms law and work out the size of the resistor you would need to know exactly what your power consumption was going to be so i guess that is out of the question as it must vary depending what you are doing at the time. Anyway has anyone had any experience with this or am i way off track? Thanks in advance.... Robbie OK another quick thought, if you actually started the car the voltage would jump to 13.5....
