Are your OCXOs in gear that draws real power?  Do you leave that gear running 
when you aren't around?

Check the numbers. 

Small UPS boxes don't have much capacity.  I'm talking home size units rather 
than monster industrial gear.  The target market for the small low-cost units 
is long enough for a PC to shut down cleanly.  That doesn't take many 
watt-hours.

I got a refurbished APC-750, partly because I can also use it to monitor the 
line voltage.

If you get serious, you probably want one of the tiny gizmos that tell you 
how much power you are drawing.  They are handy anyway.  Beware that it 
doesn't get trapped in a setup that you don't want to power down so you can 
retrieve it.
