RE: Redundant Power

It setting one up and using an old ups while testing, I found that I
could boot the 520 with one power supply on the UPS just fine, but with
both, the UPS overloaded and shut down.  Once the 520 was running, both
power supplies could be run off the UPS.  So initially, they both surge
but once running you do not see much of a difference.

This is probably a dumb question, but i'm going to ask it anyway!

When setting up i5 boxes with redundant power supplies, does the 2nd
power supply increase the load on the UPS significantly?  It seems like
it might increase the load by some amount, but i'm curious to know how
much...
