Microsoft Xbox 360 Power Supply Adapter (High Copy) 220 - 240 volt''
Place the power supply in an area where its ventilation openings will not be obstructed.
Don't put the power supply on a bed, a sofa, or any other soft surface that might block the ventilation openings.
Don't put the power supply in a confined space, such as a bookcase, a rack, or a stereo cabinet, unless that space is well-ventilated.
Don't put the power supply near any heat source, such as a radiator, a heat register, a stove, or an amplifier.
Don't stack other electronic devices on top of the power supply.
Make sure that the power supply is positioned horizontally and lays flat on the four rubber pads on its base.
If the power supply makes excessive noise, you might have a power strip or surge protector that is overloaded. Plug your power supply directly in to a wall outlet and see if the problem persists.
