Power consumption on Voyager motherboard

 American Megatrends, Inc.

Tech Tip #12.001

Problem:


Power consumption on Voyager motherboard.


+5V Current Limitation.


The Power Connector on the motherboard has 4 +5V connections, each

of these is rated at 5amps of continuous current.  The maximum

current that can be drawn on the Voyager at +5V is 20amps.


EISA/ISA Specifications:


Maximum current that can be drawn on 1 I/O slot is 4.5amps at +5V.

So, The maximum current that can be drawn on an EISA/ISA board is

equal to:


8 X 4.5amps = 36amps max.


Of this amount, the motherboard draws about 5 - 7 amps on +5V,

fully loaded condition.

Therefore on current Voyager boards, the max current available for

I/O cards is about 13 - 14 amps.

WHAT THE WATCH TOWER BIBLE AND TRACT SOCIETY OF PENNSYLVANIA HAD TO SAY ABOUT WHAT WERE SUPPOSED TO HAVE HAPPENED in 1874

Present day Jehovah's Witnesses are unlikely to be aware of any of this material. Why ? The Watch Tower had changed it's theology and does not bother to let it's followers know facts about the past especially since the present theology is totally contradictory to what was promoted in the past. Both sets of incompatible conjectures were promoted as being found  and proven in Scriptures. Prior to 1943 if a follower of the Watch Tower questioned any of the Watch Tower's teaching about 1874, that person risked getting kicked out of the group ...
