Also bear in mind that HP's published loads are significantly
overstated.  Maximum load is, I suppose, a theoretical maximum surge
when starting up a piece of equipment.  A few years ago, I sized a UPS
for a large HP system (997 with LOTS of peripherals) based on published
power requirements, and the UPS never operated at more than 30% of
capacity!  If you size a UPS based on HP's numbers, you'll have plenty
of excess capacity.
