 When I was involved in some facility sizing in the past, the concern was
what would happen in the event of a power failure when the power came back
on - i.e., all 500+ machines in the building coming online at the same
time (we had to consider this because they wouldn't pony up for a generator
at the time).

 We went with the listed power requirements and now, even though we now
have a generator, a 56KvA UPS and several 36KvA UPS', we're very glad we
did because we've got oodles of power. Now if we can just keep the city
from shorting us out...
