What is the power consumption of the 8742HDC Set Top Box. It accepts 12VDC, but no where can I find the power. Elsewhere on the Internet one individual indicated 23 Watts. Is that accurate?

The reason for this question is that we'd like to power the 8742HDC using a 12 V UPS that can support a power drain of 30 Watts. Want to ensure that this backup unit is adequate.

The Cisco 8742HDC has a maximum power draw of 36 watts.  Using my power meter I measured the actual power draw at about 21 watts. 


The power adapter produces an output of 12 volts DC at 3 amps.  The box is pretty effecient on power and uses a Western Digital Green Power hard drive.


I think that a UPS with support for 30 watts should be sufficient to power the DVR.
