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 300 watt power
supply, which should have built-in filters to suppress
radiated emissions.
Attach the power supply cables to the power connector on
the motherboard. ATX-compatible power supplies have
two 20-pin connectors, JP7 and JP10. The power
connector pinout is:
