Power Supply and Cables

The 400 Watt power supply has a manual switch for selecting either 115 V AC (90-132 V AC)
range or 230 V AC (180-264 V AC) range for domestic or oversea locations. The input frequency
is 47-63 Hz, single phase. Input current is 8.0 A maximum for the 115 V AC range and 4.0 A for
the 230 V AC range. The power supply has a minimum efficiency of 70 percent at maximum
output load. The power supply is enclosed in a case that includes a fan for additional airflow
through the system.
The power supply has the following DC output specifications.
Outputs
Nominal Output Voltages (V DC)
Maximum Current Rating (A DC)
1. Standby +5.0 V DC output voltage is always on.
2. Maximum +5.0 V and +3.3 V combined power is 300 W.
The power supply has two power cables, P1 and P2, that connect to J1 and J2 on the system board.
The power supply has six peripheral device power cables (P3, P4, P5, P6, P7, and P8) and one
floppy disk drive power cable (P9). These cables connect in daisy-chains to the power supply and
to each other as follows:
