Watt usage

JeanMJeanM Posts: 1,117Member
So I was curious on how much power my hardware is using so I ran these through a watt meter and here are the results:

3640 50watt
3725 38watt
2620 13watt
2620xm 13watt
2621 12.8watt
2950 16watt
3550 not poe 42watt

Then I decided to check the pc and monitor as well, just for grins -

old viewsonic 20" lcd = 38 watt
p4 i3 2100 with 16gb of ddr and 2 sata drives (not ssd) 50-68 watts depending on what it's doing
sleep mode = 2 watts

And to compare the with some other common devices -
40" samsung lcd tv 64watts
dvd player idle 1.3watts to 7 watts running
wd media player 4.3 watts running
Now, gotta love electric tea-pot and hair dryer at 1400watts!

    Thanks for the info - is that everything in your lab?
    Had all of my WGU courses but too much to keep up on. I am working at it, will let you know when finished.

    Amazing that the 2600 series routers run at those wattage levels. 802.11af PoE could power those.

    Just wanted to share this with others on the forum, questions about power come up from time to time. Now I don't feel too bad about leaving a couple devices on 24/7 :)

    That's fantastic info to have, thanks Jean! Now you make me wish that I had a watt meter so I could test my own stuff!

    A very useful cheap one in the USA is available for $20 from Newegg, I think Amazon carries it also

    The P3 is the one that I use frequently. It is a very good unit, even at such a cheap price it has held up for years.

    Interesting. I wonder how much they pull when they first startup. My 2821 is pretty loud when it first starts, but quiets down once its loaded and running. I was worried that I might have to run another circuit from the breaker box if I wanted to run all my equipment at once (10 Routers, 4 Switches, 1 PC, 1 Wireless AP).
