Connect Power Supply The power supply should match the physical configuration of the
chassis. Make sure the power switch is off before assembly.
Before attaching all components, make sure the proper voltage has been
selected. Power supplies often can run on a wide range of voltages and must
be set (usually via a switch) to the proper range. Use at least a 450 watt power
supply, which should have built-in filters to suppress radiated emissions.
Connect Power Cables Attach the power supply cables to the power connector (P1 and P3) on
the motherboard. AT-compatible power supplies have two six-pin connectors,
attached as shown below. The six-pin connector on the power cable with three
red wires and two black wires is attached to P3. The other connector on the end
of the power cable is attached to P1.
