A question for those living in 120v/240v countries
for those of you living in counties with the the 3-wire dual voltage system that has 120 volts and 240 volts (or 208 volts when tapped off 3-phase or 127v/220v in Mexico) ... who connects their 100-240 volt capable computer power supplies to 240 volts?
advantages:
- computer continues to run when there is a serious brownout (some can go to half voltage).
- voltage is balanced so there is no 60 volt phantom voltage that can mess with digital voltage meter readings.
- some power supplies are more efficient at higher voltage up to their max.
- lower current on building wiring means more efficiency (why the power company uses 12000 volts and higher).
disadvantages:
- requires wiring in a new circuit if one was not already there.
- uses 2 slots in the breaker panel instead of the usual 1.
- may not be allowed in some places (may not pass inspection if one was done).
- UPSes are more expensive (need commercial/industrial grade versions).
- fewer power strip and surge protection options (but some do exist).
