The Power Limit Modifier is designed to work as an adjustable shunt resistor for graphics card power limit modifications. It works by adjusting the gate voltage of a P-channel MOSFET which acts as a non-linear resistor. Simply solder the small circuit board in parallel with the existing shunt resistor. Then solder a wire from the square pad to the VR (variable resistor/potentiometer) and a second from the VR to ground. Adjusting the VR will then vary the gate voltage and in turn the equivalent resistance of the MOSFET.
