• Make sure that the red voltage switch (located on the back of the
power supply) is set to the correct voltage setting. The setting for
the United States is 115 V. The setting for Europe and other
countries is 230 V.
• Make sure that the system board power supply cable is securely
connected to the system board connector (24 pin or 20 pin).
