Overview
A buddy of mine asked me to convert an old computer power supply to a bench supply that he can use with a LiPo charger to charge his Traxxas Slash batteries. Because these LiPos often come in between 4000mAh and 12000mAh ratings, even just charging them at 1C would easily require 10A per battery. A typical linear power supply can only provide between 500mA and 2A where a switching computer supply can easily supply 20A per rail with 2 to 3 rails. Computer power supplies are also relatively cheap which makes them a perfect candidate for this project.
The victim for this modification is an OCZ 500W power supply. Comes with two 18A 12V rails and 24A 5V rail. The two 12V rails can be combined for greater power.
