Heat and Power Consumption, Continued
The American Megatrends Super Voyager VLB-III motherboard requires +5V
and 7A. The +12V supply current to the ISA Bus is limited by the power
connector.
Power Supply Requirements
The Super Voyager VLB-III ISA motherboard requires +5V, -5V, +12V, -12V,
and about 44 Amps maximum.
Power Consumption
The SIMM memory banks consume 2 Amps each, for a total of 8 Amps.
Each ISA expansion slot is gated at 3.0 Amps maximum. Each VL-Bus
expansion slot is gated at 4.5 Amps maximum. There are six ISA-only
expansion slots and two VL-Bus slots, so the total maximum power
consumption for the expansion slots is 27 Amps. The total maximum power
consumption is 35 Amps at +5V with a 220 Watt power supply.
Power Source
Two power connectors (P1 and P2) are provided on the Super Voyager VLB-
III motherboard.
Conclusion
The minimum rating of the power supply should be 220 Watts for a fully
loaded motherboard, including a 12V power source.
