Not a technical answer, but maybe this will do.  
I wanted to have as much as 30 minutes run time for 
a fairly typical latter-day system, if and when there 
was a power outage.  I also wanted plenty of power 
connections, not easily obstructed by outsized power 
plugs (like those squared-off brick-style plugs), 
plus whatever good and competitive features you would 
get from the better UPS'es.

What I found, in order to match the above, is that 
there is a certain line you cross where the units 
just become too heavy and too unwieldy for practical 
SOHO use.  For me, that line was crossed at the next 
jump _above_ the APC Smart-UPS 1400 -- so that is what 
I got.  I think it works out to supporting 700 watts 
total.  (But, if you have one of those dual-slot, 
monster gaming video cards that draws huge watts, this 
may still not be a lot.)  Prior to that, I think I 
had APC's Smart-1100 (?), which was a bit smaller and 
lighter.  

I got a certified refurb this time, from a company that 
I've used for UPS sales / service for many years, and 
it cost less than what I expected.  But, unless you are 
within driving distance of Canoga Park, that might not 
do you much good, since I think shipping costs would 
be prohibitive on account of the considerable weight.  
There is some possibility that this company has other 
locations, not just in SoCal.  But you can easily 
find that model from numerous other vendors.
