Power Specifications
Power Supply Requirements
The American Megatrends Baby EISA motherboard re5V, -5V, +12V, -
12V, and about 40 Amps maximum.
Power Consumption
The two SIMM memory banks consume 2 Amps each, for a total of 4 Amps.
Each EISA expansion slot is gated at 4.5 Amps maximum. There are eight
EISA expansion slots, so the total maximum power consumption for EISA
expansion slots is 36 Amps if all slots are filled.
The total maximum power consumption is 40 Amps at +5V with a 220 Watt
power supply.
Power Source
Three power connectors (PS1, PS2, and PS3) are provided on the Baby EISA
motherboard. These connectors provide seven +5V connects. Each is rated
at approximately 5 Amps. The total maximum power consumption for all
three connectors is approximately 35 Amps.
Conclusion
The minimum rating of the power supply should be 230 Watts for a Baby
EISA motherboard in normal use, including a 12V power source. But if all
EISA expansion slots are used, a 350-400 watt power supply may be
necessary.
