I have heatsinks and fans now. It is time to start testing the power supply, first that it puts out clean 12volts and second that it can handle a load up to the full 500 watts. We will use the Flir camera on this one as well as a thermometer device to monitor temps. Also we may have an oscilloscope to check the power output is clean as well. ( I mean it should be with as many chokes, capacitors and voltage dependent resistors in the circuit.
