DC/AC Conversion

In US, standard AC comes at 115V. The rest of the world uses 230V for AC. Most modern supplies support both these VAC Standards. Older power supplies had fixed-input switches that required you to set 115V or 230V

Installation

1. Take out 4 screws at the back of your case and then secure the PSU in
2. Enable the switch at the back of the PSU to turn it on
   1. If the switch is not installed, or the leads are not plugged into the motherboard, you can use a metal material to contact the 2 stop and start wires.
3. If the PSU is making sound, then it means the fan is runninng and the system is fine.
