Power Supply

Power supply is one of the important in your casing. This is how I check a power supply is good or not.

 1). Find a wire; remove copper from your wire.

 2). Unplug a power supply connector from your motherboard.

 3). from the power supply connector you can see the green wire, that wire is only one from the power supply connector.

 4). Put the wire into the green wire slot and the other part of your wire put it into the black wire slot. You can put whatever slot of black wire.

                This is how I test power supply.
