This mainboard requires a power supply of at least 200
watts. The power cord leading from the system's power
supply to the external power source must be the very last
part connected when assembling a system.
The ATX power supply provides a single 20-pin connector
interface which incorporates standard +/-5V, +/-12V,
optional 3.3V and Soft-power signals. The Soft-power
signal, a 5Vtrickle supply is continuously supplied when
A power is available. When the system is in the Soft-
Off mode,this trickle supply maintains the system in it's
minimum power state.

The poly-fuse protects the system from dangerous voltages the system might be
exposed to via the keyboard or USB connectors. In case of such exposure, the poly-fuse
will immediately be disconnected from the circuit, just like a normal fuse. After being
disconnected for a certain period of time, the poly-fuse will return to its normal state,
after which the keyboard or USB can function properly again.
