Power Supply Unit Volmodding Guide
 

There are two systems components that traditionally undergo volt-modding: mainboard and graphics card. Besides these two, you can also volt-mod the Power Supply Unit (PSU) of your computer. A simple modification allows controlling the basic voltages of a majority of existing PSUs. Read our Guide for more details about this procedure.
