UPS power backup, any recommendations?

The concern is not "Xfinity Home Security / Devices And Equipment" help related. Thread moved here to the proper help section for assistance. 

Actually, this is an appropriate place to asks this question as he is looking to protect comcast equipment from losing its mind when power fails.  Every time we have power failures at least half the time I have to completely reconfig the modem, split the networks etc.  However, you cant really ask about a UPS without being able to find someone that knows the power consumption of the XB8 modem to start with which is what I need to know because I am working on a UPS solution for my wiring closet for this reason.   Do you happen to know this answer.  I need the number of watts average for normal runtime operation of the XB8.

Thanks
