Home Network Power Consumption

Ah well in that case an instantaneous reading may not be that accurate. It would be interesting to record the Wh over, say, 24hrs and average it.

Monitoring for 15 minutes thats long enough… ;)

I measured 6 watts for a cisco SG200-08 switch
My first server with a pfsense is with a Asus Pundit-R (p4 2.4 GHz, 1 GB ram, 2 x intel PCI pro1000 network cards and 8 GB SSD) at around 60 watts
Seems a bit high, as i run a freebsd based nas with a Xeon 1265Lv2, 32 GB ram and 20 * a 7200 rpm hdds which uses 180 watts.
I have spare mainbord with 8 GB memory and could try a xeon 1220Lv2 and a very efficient power supply. Perhaps that consumes less, but is a 400 euro investment.
This pundit has no issues doing line rate donwload at 120 mbps which is nice, and it does not need to be a much faster machine for me i guess.

60W for a P4 seems about right unfortunately. The Netburst CPUs were notoriously power hungry and I expect your desktop model has no power saving features. My own P4 box with 2.8GHz desktop CPU idled at ~55W but it has no video hardware. I replaced it with a P4-M which idles at around 40W. Still not great. :( I'd replace it but it has 9 on board Intel NICs and runs rock solid. :)

Interesting thread, can contribute some more data:
Cisco SG300-10: 6 W
Cisco SG300-28: 10 W
pfSense machine: 33 W (Atom D-525, CF, 1xWLAN, 4 GiB DDR3, no keyboard, no monitor)
Desktop management machine: 160 W (Asus P5E3-Deluxe, 8 GiB DDR3, 4xHDD, 2xDVD, 1xWLAN, 2xEthernet, 19" TFT, USB keyboard, not yet measured under heavy game load :))
Backup pfSense machine: 6 W (Alix.2D13, 1xWLAN, CF)Peter

Xeon E3-1230v2, 16GB RAM, 1 SSD and 4 Hard Drive, 350W 80+ GOLD: around 50W IDLE (probably I can arrive to 40W if I disable Supermicro IPMI and I slow down/remove some fan)
Watchguard x750e with Pentium-M, PowerD and DC-DC brick: about 25W
HP 1800-24G: about 15W, depending on how many ports are connected -
60W for a P4 seems about right unfortunately. The Netburst CPUs were notoriously power hungry and I expect your desktop model has no power saving features.
With some traffic i saw 90 watts. So i ordered a new mainbord/psu (msi c847ms-e33)
According to tests (its brother, the p33 was tested) it uses around 20 watts idle -
Total as shown by my UPS, I don’t have the breakdown per unit: 27 – 31 Watts

Nice power usage numbers Downloadski :) …. what device did you use to measure power usage?
-
a plug in the wall outlet type of device (live in Netherlands Europe)
I have it since years and not a idea how precise it is. This PC uses half to a third from the test pc i used to check pfsense out.It might be a unit made by Cresta.

To quote the Cresta RCE1106 manual:
Accuracy:
- Voltage: +/-3% of value measured
- Current: +/-3% of the value measured +/-0.03A
- Power: +/-5% of the valve measured +/-10VA
- kWh: +/-5% of the value measured+/-0.1kWh
That seems about what I'd expect from a plug top style meter costing <£50. I imagine my own meter is similar. I have a hard time believing the figure giving by Kill-a-Watt. :-
This seems to support that: http://forums.anandtech.com/showthread.php?t=137169I'm not going to stop using it though. Much better to have some reading for comparison that no data. :)
