Home Network Power Consumption

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. :)
