Power Consumption Meter

[~Divine~Wind~]

just wondering if anyone has any experience of using one of these?

Im starting to wonder which of my PC's consumes the least amount of power whilst Idle so I can use that one for my DL/media server.

any recommendations?

I use the meter below:

My PC consumes around 320w full load, E8600 @ 4.4GHZ, 8800GTX,2 Hard drives and watercooling.

I have a couple. Ive bought them from aldi/lidl in the past. Work fine!

Pretty cool device, wish OC would sell something like that, thanks for the link

i use one from a competitor

specs

b3 q6600 @ 3.2GHz (not prime stable)
4870 stock
3450 stock
3 HDDS

340W when folding with 1 cpu and 1 GPU client ,this is not at load

about 220W idle

never attempted to get a readign at 100% load

Just remember that unless PSU has active PFC these cheap power meters can give nearly 50% too low reading depending on how far current draw is from sinewave and what's the phase displacement:

The link isn't much use to English speaking folk, but the content looks like it might have been interesting...

Curious - is there any software out there that will do this job? Or is it (as I'm thinking) impossible?

You can always try translation of Google:

Yellow curve is voltage, green current and purple power.
On top of the graph are values shown by meter and actual power consumption calculated by oscilloscope. Below graph there's apparent power (voltage x current) you would get by measuring current using True RMS meter (basic meter can't measure non-sinusoidal current/voltage correctly) and power factor.

First load is obvious and second basically capacitor just cycling current back and forth and not consuming anything. (negative power half of the time)
Third one is apparently one of those transformer powered fluorescent work desk lights. (current behind voltage means inductance) Topfield is DVB receiver (SMPS) and Harman Kardon audio amplifier using transformer followed by rectification. (compare current to that of table desk light)
Next one is again obvious, Finlux is CRT TV with basic SMPS and Eizo has PFC. (about sinusoidal current draw instead of spikes)
