Measuring Power Consumption
I bought a Kill-a-Watt power meter some time ago and used it to measure how much power my MAc ***** up. I currently have a Mini and it's power consumption I think is tremendous. I am considering purchasing a MacPRO sometime in the next few months and was wondering what the MacPro, or any other Mac for that matter, uses in electricity in 3 different modes: sleep, pegged, running
Mac Mini:
running: 19-20 watts
pegged: 33 watts
sleep: 2-3 watts
Also, please post how you measured the electricity used.
Thanks, Jim

VI that measures power consumption(HP 4155A)
can anyone help me in writing a VI for measuring power consumption
using parameter analyser 4155A.
Iam using HP 4155A semiconductor parameter analyser for setting up constant power source to the circuit.
now i have to measure the power consumption.GoHere

How to measure power consumption of a brushless DC motor
Hi,
I need to measure the power consumption of a moog 23-23 motor using a PXI platform because I need to save the instant power consumption data. I have a Dqmx 6259 and a FPGA module. The problem is that I don't know if I should measure the current and voltaje of all three coils of the motors or if it is enuogh measuring just one, plus is it better to measure in differential mode all the signals directly with the DAQmx or shoul I use a differential amplifier first?I don't see anything wrong with your approach; however, I'll throw out a few thoughts:
If you could tie the sending of the change-voltage command (in your DLL) to the START TASK command for DAQ, you could reduce the variability in the time between the two events. Maybe that's important, maybe not.
Can you set the voltage via some LabVIEW code, rather than a DLL?
You might or might not want a variable sampling rate - if you expect 10 mSec, you might want to sample at 10 kHz to catch the 1% difference between 10.2 and 10.3 mSec. But if you're expecting 500 mSec, you could sample at 200 Hz to catch the 1% difference between 500 mSec and 505 mSec, thereby saving data space and processing time. Maybe that's important, maybe not.

Quad G5: Actual Power Consumption
I haven't seen the numbers posted, so I thought I'd share from this config:
Quad 2.5 Ghz G5 (Rev A, dual pumps)
4.5 GB PC2-4200 RAM (4 x 1 GB, 2 x 256 MB)
Geforce 6600
Western Digital 250 GB SATA Drive (WD2500JS)
Seagate 400 GB SATA Drive (ST3400832AS)
No firewire or USB devices connected (except keyboard, mouse)
Here was the measured power consumption (in watts):
455 Peak measured (with 4 CPU's at 100%, disks writing)
275 Idle (CPU at Highest)
245 Watching a DVD (CPU at Automatic)
210 Idle (CPU at Reduced)
43 Mac Sleeping
The specs page lists "At least 10A" required at 120 volts. Even if you squeezed 9 drives into the G5, I don't see how one would ever approach 1200 watts.
I use a Belkin 1500VA (830 watts) UPS, which is 55% loaded when the Quad is at its peak, and can sustain that for around 10 minutes.
At 7 cents per kWh, running BOINC could cost 77 cents per day, running idle would be 36 cents, and sleeping 8 cents.I posted similar results a few months ago. Amazing that people were worried (when the Quads first appeared) that they'd have to run new power lines to support them.
I used a 'Kill A Watt' to measure - what did you use? -
+5W power consumption when playing audio on X201 with Linux
Hi folks!
My Thinkpad X201’s power consumption raises from ~10W to ~15W when playing any kind of audio under linux. This problem does not seem to be CPU-related (for example when streaming with pulseaudio over ethernet instead of playing directly on the X201 the power consumption does hardly increase) and does not occur under Windows. I’m using Fedora x86_64 16 with Kernel v3.2.1 but it also occured with a v3.2.1 vanilla kernel; Fedora 14 and 15; Ubuntu 11.10 and 12.04 and so on.
I’ve allready posted my problem several months ago here: http://forum.thinkpads.com/viewtopic.php?f=9&t=99246 but haven’t gotten any useful answers.
I measured power consumption with powertop but also confirmed with readings from /sys:
while true; do bc -l <<< "$(cat /sys/class/power_supply/BAT0/current_now)/10^6*$(cat /sys/class/power_supply/BAT0/voltage_now)/10^6"; sleep 1; done

Is anyone able to confirm this problem or does anyone have a solution? I’m really desperate since I often use my Thinkpad as a big but wonderful portable music player (with headphones of course! Don’t want to annoy my fellow trainpassengers …).

I have a Nokia N86 which is 2 years old.
I have been experiencing a problem with battery drainage since I bought it. The battery meter suddenly drops from 5 bars to one bar when I browse the net using HSDPA, after about 30mins or so, when the phone is already hot. I sent it into service once, because it happened very randomly and it did not look like a major issue. They said they recalibrated the battery. After a week of somehow uniform battery draining, the battery started going flat suddenly, again, from 5-6 bars to "low battery".
I went to a service center again to check if it's the battery or the phone. Nokia Energy Profiler says that the current is about 400-500mA when using HSDPA. The engineer at the service center connected a power supply with measurable current consumption, and during the usage of HSDPA, the current was at least 800mA, with almost 1000mA peaks. He said that these current intensities damage the battery in about a month and that he would not recommend changing the battery, but the HSDPA chip. The warranty period expired a month ago.
I am asking you guys:are these values normal? 800-1000mA during HSDPA usage for a Nokia N86? I need a serious, valid opinion from somebody who really knows mobile hardware. Thank you.This has happened to me every now and then. First it seems as if the battery is almost full and then it's suddenly empty even without using the device much.
Sometimes the device feels warm. In those cases I just reboot it.
Obvious things to check would be that BlueTooth and WLAN are off if you don't need them.
Sometimes the switch of the kickstand has activated when I have carelessly thrown the phone on a bed for example. If you have defined it to start an application that could cause some power consumption.
I haven't tried to measure my power consumption. I guess there are two options:
- the device actually consumes a lot of power sometimes
- the battery indicator isn't always up-to-date i.e. it shows several bars when the battery is actually almost empty.
It's a shame because it's a pretty nice phone and I quite like it. Luckily it's quite a rare problem.
(But not that great if the battery dies during a bicycle trip just because I have SportsTracker running.) -
Hello,
i'm running a little media server on clarkdale basis (MSI H55M-ED55, Intel i3-530) with sound chip ALC889.
Kernel is 2.6.32.9-1-ARCH and architecture is x86 Archlinux.
The hardware is supported nicely so far however there's one thing i'm not very happy about.
When playing music the power consumption climbs from 20 Watts (idle) to 28 Watts although the workload of the CPU is only 1%.
Enabling power_save for the chip alone saves 2 Watts when idling.
Compared to the consumption of the audio chip in Windows 7 which is 1 W at most the 8 Watts are unusually high for a sound chip. Is that a known issue or do you know if it can be resolved somehow? I've tried kernel 2.6.33 but the high sound consumption remains.
I assume it's just a kernel driver thing which i can't do anything about but I'd be glad to hear different.
Regards,
demian

Actual power consumption on WS-C6509-E
Hello everyone,
I have a WS-C6509-E with two WS-CAC-6000W power supplies. I have to determine what is the real power consumption of the whole device but I noticed that there is a mismatch between measurements and show power output so I would very much appreciate if someone could explain why is that so.
I did the following test to try figure out the consumption from the power grid.
Step 1. When both supplies are active, show power gives me the following output:

Step 4. I used the current clamp to measure the current on the remaining power input and it reads 4.9 A.
When I multiply the current with voltage I get
P=4.9*230=1127 W.
So why does the show power output gives system power used = 2253.72 Watts, which is actually double value of measured 1127 W? What am I missing?
Thank you in advance for any help on this,
Marinmarin_otto.
Where are you located and what AC line voltage are you operating on (208 or 230v)? I ran into your post and was wondering if you were operating on 208v which is line to line (two hots) and perhaps you are only measuring current on one line, effectively half the power.

We operate tens of macbooks at our campus for student loans. We are trying to cut on the power consumption of the loans operation. I am interested to know how much power does the power brick consume when:
a) nothing is connected to the MagSafe jack.
b) the macbook is fully charged and the LED is lit green.
Please don't guess or think! give me a firm answer if you know. I appreciate that!I pulled out my 1940s era General Electric Wattmeter. This is a two-coil instrument that measures Vrms * Irms * cos( phase angle) = actual Watts. This type of meter does not measure reactive power that does not deliver energy to the load but circulates in the system. Reactive power is a concern because the out-of-phase current of reactive power does cause energy loss (I squared R loss) by heating the wires carrying the current.
Power brick energized, but not attached to computer - unmeasurable.
Power brick energized, attached to computer, green LED on - about 0.7 Watt.
Power brick energized, attached to computer, OSX booted, but idle - 8 to 10 Watts.
Power brick energized, attached to computer, screen saver running - 8 - 12.5 Watts.
Power brick energized, attached to computer, 5th Element DVD playing - 12.5 -15 Watts.
Power brick energized, attached to computer, Grapher, contours.gcx - 18.5 - 20.5 Watts.
Once in a while, I could get the MacBook to peak at about 25 Watts (averaged by the mechanical dynamics of my meter) of power consumption. The initial plug-in of the power pack to the socket also consumes several amps for a split second - too hard to measure accurately with my crude equipment. There's also a little audible crack! as the prong touches the outlet, so it is obviously a pretty large momentary in-rush of current.
When the power brick is unplugged, the Irms current draw is about 22 mA according to my Fluke 8060A. Presumably that's almost all reactive at close to -90 degrees phase angle relative to the voltage. Switch mode power packs like the MacBook's tend to be capacitive loads. That's about 2.64 VARs of reactive power.
When the MacBook is idling at about 9.5 Watts of real power consumption, the current draw is about 245 mA. The real power corresponds to about 70 mA of in phase current. This gives the surprising result of about 234 mA of lagging reactive current.
In terms of what real-world thing can you do? For 10 to 100 MacBooks, I don't belive it is worthwhile to do anything. Probably remediating the power supply to reduce the reactive current load would be good thing. At industrial scales, factories worry about current phase angle a lot. Power providers bill for reactive current they have to generate, otherwise they would lose revenue by heating their transmission lines, but the customer gets no energy delivered to the manufacturing process by the out-of-phase reactive current.
Probably, the energy consumed and eventual environmental waste generated by remediating 10-100 power supplies, not to mention the engineering hours required, would not offset the power that would be saved over the useful life of the MacBook.
On the other hand, grumbling at Apple to contract with the manufacturer for a greener design for the power pack for the many thousands of users would be a good thing on which to expend a little energy.
PS: just to be sure my Wattmeter is giving reasonable results, I plugged in a "60 Watt" bulb that's been used for about 200 hours. According to the meter, it draws 58 watts.

I was reading an article on tomshardware.com the other day in which they described a process by which they were able to measure the power consumption of various video cards using a simple device that plugs into a standard wall socket and then displays the number of watts the currently plugged in device is using. In light of the ever-increasing PSU recommendations that tend to show up here (I recall seeing one poster recommend "a PSU with 24 or more amps on the +12V rail for anything other than a barebones system"), I decided that it might be beneficial to these forums if I did a little empirical study of my own. So anyways, I shelled out ~$30 for the device shown here:
http://www.supermediastore.com/kilwateldet1.html
...and ran some tests of my own. The results:
Preliminary Testing -
To verify that my power meter would give reasonably accurate readings, I first hooked it up to a 3-way lamp with a 50/100/150 watt bulb installed. The readings returned for the 50/100/150 watt settings (respectively) were 44/94/142, so it would seem like my power meter is at least reasonably accurate. Some other stuff I measured just for the hell of it...my speakers use 3 watts of power in stadby mode, and 30 watts when active (haven't yet tested when active and playing at full volume), and my monitor uses about 70 watts when on, and about 2 watts in standby mode.
Results -
Satisfied that I had not just wasted my money on an inaccurate power meter, I then went and hooked it up to my PC (the one described in my sig) and measured the power consumption under a variety of circumstances. It is important to note that these readings reflect the total amount of power drain being applied to the wall socket, not the amount of power that is actually being demanded by the system. This is because no PSU is 100% efficient (a good one will be maybe 80% efficient, if even that much), so the amount of power that is actually needed by the system is actually about (at least)20% *less* than the recorded values. Anyways:
During startup, the power usage spikes very briefly at 197 watts, then averages 152 watts over the rest of the boot cycle.
The system uses 134 watts of power when idling.
Under full CPU load, the system uses 168 watts.
Running 3d Mark 2001 the power usage is 169 watts.
Playing Far Cry (high detail settings, 1024x768x32), the power usage is again 169 watts.
Conclusions -
So, let's now assume a worst-case scenario, in which the extra 34 watts recorded during full CPU load came entirely from extra CPU power drain (a reasonable assumption), and in which the extra 35 watts recorded during 3d Mark and Far Cry came entirely from extra video card load (a much less reasonable assumption), and in which we have a PSU that is 90% efficient (greater efficiency means that the system would actually have to demand *more* power in order to get the total power drain up that high). In this case we see that if an application were developed that fully taxed the video card and CPU continuously, the total power drain would be 134 + 34 + 35 = 203 watts (which actually correlates rather nicely with the 197 watt spike observed during the boot cycle), meaning that the system is demanding about 183 watts from our unrealistically efficient PSU (note that with the PSU efficiency set to a more realistic 75%, the system would only be demanding a mere 153 watts of juice at full CPU and video card load).
Admittedly, the video card in my system is relatively weak, so let us again take the worst case scenario and assume that if I were to be using a 6800 Ultra, the total power drain would be 100 watts greater (this is above what the actual difference should be given the results posted on tomshardware.com regarding the power use of the 6800 Ultra), so our video card now consumes an astounding 135 watts of power, and our total power drain (in our unrealistic situation where we have some application which is capable of 100% CPU and video card utilization for a sustained length of time) is now 303 watts. With our unrealistic 90% efficient PSU, it would mean that the system is demanding about 273 watts from the PSU (about 228 watts with a 75% efficient PSU).
Note that aside from the weak video card, I have a fairly robust system (which also happens to be slightly overclocked), with 4 HDD's (two of which are WD Raptors), 2 optical drives, several PCI devices, and two large 120mm case fans, and yet the power demands of this system, even in an unrealisticly demanding situation, are *well* within the ability of a quality 380W (or even 300W) PSU to deliver. In this case even if all the power happened to be being sucked off of the +12V rail (which is not the case), any PSU with 18 amps at +12V could still handle it. Furthermore, even if I were to add a needlessly power-hungry video card into the mix, the power demands are *still* safely within what any decent 380W PSU should be capable of (and even what a quality 300W PSU should be capable of, although this may be pushing it a little, though it should always be noted that the numbers indicate a hypothetical worst-case power drain that should be beyond the maximum drain possible in any real-world situation).
So, we can therefore conclude that the power demands of a reasonably robust Athlon64 based system are not astronomical by any means, and that they do not justify a minimum recommendation of a 465W PSU with 24+ amps on the +12V rail for any system which is not "barebones," and that there is no observational evidence to support the idea that a PSU with 18 or fewer amps at +12V is categorically inadequate for use in an Athlon64 based system.
...anyways, I guess that's all, I hope you found this interesting, or at least informative. I'm off to see what else I can do with my power meter thingy...Really? Do you have measured data which clearly supports your claims, or are you just holding up an opinion as a matter of fact?
My point was, my measured results show that the total power demand of an Athlon64 based system across *all* of the rails is fairly low, even at 100% system load. So, let's recalculate things assuming a 75% efficient PSU, with 75% of all load being at + 12V (which is still probably higher than the actual value), and let's leave the hypothetical 6800U inside of my system. We get .75 * 303 = 227 watts in total that the system is demanding. Of these 227 watts, the system is demanding .75 * 227 = 170 watts over the +12V rail. 170 watts / 12V gives us a total demand of 14.2 amps on the +12V rail. Note that this is with the hypothetically demanding 6800U card installed and is still likely to be at least a couple amps higher than what a *real* system would ever use, and any *quality* PSU capable of 18 amps at +12V should still be perfectly adequate for use in the system.
Furthermore, PSU efficiency dropping to 60% in real world situations supports my results, as it means that the actual system was demanding substantially *less* power than the system in my hypothetical example, making things even *easier* for the PSU. Re-running the above equation with a 60% efficient PSU and 75% of all power demand coming from the +12V rail, we see that the system is only asking for 11.4 amps at +12V at full load with a 6800U installed (and also at full load).
If you want to disagree with my results, that's fine, but don't expect me to take your argument as credible unless you have some actual, measurable data to back up your claims. Saying "this is the way things *really* work because I say so" doesn't cut it, so until you want to break out a multimeter and measure the amps your PSU delivers to the MB on the +12V rail at boot, idle, load, and gaming and then report your results and discuss whether or not they are consistent with your "amps are what counts" hypothesis, I hold my results and conclusions up as being valid, and as soon as I see any measured results which contradict mine, I will gladly stfu about PSU recommendations being needlessly high. -
I915 power consumption issue after switch to systemd?
After switching to systemd I noticed a massive increase of power consumption on my Thinkpad X220 (i5 Sandy Bridge).
The strange thing is, that after some reboots it randomly seems to catch the i915 power saving mode and the consumption gets from ~24W to ~7W at idle. But only after several reboots.
Adding the good old i915.i915_enable_rc6=1 to the boot parameters doesn't make any differences. But looking at the powertop detail outputs it seems to be a i915 issue.
Using the latest linux kernel from core (3.6.4) and latest intel drivers (2.20.12).I started to get suspicious because I have only ever had the issue in my office. Last week, when I encrypted my drive, my machine wrote to disk for more than 14 hours solid. I then did all the set up and all the restoring from backup etc. with no issue whatsoever. Lenovo ran the thing for 48 hours straight with no problem. But once in my office...
So I asked the local IT people if they could think of anything other than overheating and explained the issue. They took my laptop yesterday , booted it from a hardware testing CD and ran it for a couple of hours sitting on top of a hot computer in the server room which is definitely hot. (It has a whole bunch of computers, I guess.) No issue. They then ran stress tests for a while in the same place. No problem. Highest recorded temp: 65C.
The head of IT then took my power adapter to a more general IT service to be tested and inspected. They looked at it, they opened the plug to check the fuse, they tested it. No problem. Of course, the guy also explained why he was asking and the other IT person said, "Oh, is that on level 1?" "Yes..." So apparently there was another machine (a Mac), I think, doing just the same thing in an office in my part of the building. Testing showed that the power spikes and when the power spikes, the laptop shut down as a safety measure. Solution: they installed a UPS for that one laptop. They didn't tell anybody else, including the local IT people.
What the local IT people were going to do was to install equipment to monitor the power in my office and see if anything weird was causing my laptop to react. However, that was when this was an extremely-unlikely-but-we-are-getting-desperate-for-theories scenario. Clearly, that theory no longer seems wildly implausible at all. So the current hypothesis is that it is most likely that my machine is also reacting to the spikes in power by shutting itself off. (I'm not sure why it should have just started doing this but who knows what the state of the electricals is and how that might vary?)
I have been told that a surge protector will do no good. (They've given me one anyway but apparently it will not deal with spikes in phase 3 power or something - I didn't understand this bit but the head IT person said he didn't understand it either but the electricals IT person showed him with graphs on the whiteboard. So it must be true.)
The current plan is to try to get the UPS from central IT which was provided for the other laptop since that person's discipline has since moved to another floor of the building so the UPS probably went back to central IT. They are going to ask during a meeting tomorrow about this possibility. Otherwise, they are planning to order a UPS for me on Monday.
I'm somewhat surprised that the abrupt shutdowns haven't screwed my data. I've lost work but not seen fs corruption. I didn't take my laptop today. I'll need it next week but I do not plan to plug it in in my office until I have a UPS.
I'm pretty annoyed, to be honest. I've wasted hours on this and got incredibly stressed about it. The IT people have also wasted a (smaller) amount of time. I hoped to have a new draft of an article I'm working on written by the end of reading week but that didn't happen due to all of this. And they *knew*. It would be different if this was an unknown problem just discovered - of course, one could understand that. But there's a known problem which can cause this type of problem and presumably could well damage equipment without these sorts of safety shutdown features and they don't tell anybody.
And, no, I doubt very much indeed that a damaged personal machine would be considered the institution's liability. (Maybe if it was a student's machine and the student was required to use it or something but even then...)
I can't believe it does much good to their equipment either.
The local IT people did know there was an issue with some burnt out devices but that was about eight years ago and only got mentioned as a outside possibility when other diagnostics turned up no result.
What gets me is that the proposed solution will only solve the issue for me - not for anybody else in my part of the building on level 1. -
Higher power consumption after suspend
Hello,
It seems that my power consumption is significantly higher after resuming from a suspend than before. I suspend with the systemctl command. Measuring the battery usage (with powertop or looking at /sys/class/power_supply/BAT0/power_now on my laptop), I get the following numbers :
- 6-7 W before suspend
- 10-11 W after
Those number are quite stable in time, in particular the higher consumption stays until shutdown. I have tried looking at the power decomposition of powertop, and it seems that the backlight display consumption is indeed higher, although I keep the same luminosity level. I tend to consider the decomposition usage by powertop as a guess estimate anyway, so I am not sure whether this means anything.
Any ideas on how to solve this issue, or how to investigate further on?
Cheers,
GuillaumeHave a look at powertop before and after suspend. I noticed that some power saving options get turned off when suspending. I don't have a solution though.

Power consumption double compared to windows... where could energy be
I just bought a new Laptop (Acer Aspire 5755g), and first thing after I got it was, of course, installing arch ;-)
However, I noticed that the energy consumption under Linux is at least about 22 Watts in idle mode, while it uses only 10 Watts on the preinstalled Windows 7. I was wondering where the big power leak could be. That's what I already thought of:
• I enabled most of the laptop-mode energy saving options, that means ondemand CPU governor, soundcard/ethernet/wireless powersavings, usb autosuspend, hard drive power saving etc...
• Since it is a nvidia optimus laptop, it has two graphics cards. However, I disabled the nvidia graphics card in the BIOS (what saved about 5 Watts), and I think the remaining "cheap" intel chip should not use that much power.
• The laptop has an LCD LED display that can be quite bright. However, the 22 Watts are measured when background light is almost at the minimum.
Are there any ideas, where else the problem could be?
I know of the kernel power regression discussed on phoronix recently, but can this really double the power consumption?rggjan wrote:
I just brought it down to under 8 Watts! Using this trick:
http://www.phoronix.com/scan.php?page=a … ower&num=1
What made the laptop finally turn of the fans, and really saves a lot of power...
Indeed, this and the pcie_aspm option, plus disabling the NVidia card with power management from Bumblebee (extra dangerous BTW, I would not recomend, though I use it) and unloading some modules, took my Alienware M11xR3 consumption down to 7.95W. -
Thinkwatt: record power consumption and visualize it with gnuplot
https://github.com/mikar/thinkwatt wrote:
Thinkwatt is a bash script for use with thinkpad laptops. However, as of v0.2, it works with all kinds of laptops as long as they've got a battery attached.
Thinkwatt can
* record your power consumption,
* calculate an average of that consumption
* and visualize that data in a 2D gnuplot graphic.
options:
-r, --record record power consumption and optionally create a graph from the gathered data
-p, --plot create a plot image from a specified data file
-a, --average calculate the average power consumption from a specified data file
-q, --quiet makes thinkwatt less chatty
-o, --output the output file. can be prepended by a path.
-h, --help show this help text
examples:
thinkwatt -r (will record to a temp file until cancelled)
thinkwatt -r 300 -o /foo/bar/consumption.dat (will record for 5 minutes to the specified file)
thinkwatt -p /foo/bar/consumption.dat (will create a graph from the specified file)
Thinkwatt works with all laptops, not just Thinkpads.
If you're running thinkwatt on a Thinkpad it is still recommended to use tp_smapi as it provides more accurate results than the generic acpi.
This is an example of what the graph can look like:
It's mainly useful for retracing power consumption during certain situations (e.g. measuring the influence of certain hardware or software (kernel comes to mind), or simply reliably gather typical power consumption for certain activity profiles like surfing, working, watching movies etc.)
I guess I'll add to the script when and if time and my bash skills allow it. Suggestions for improvement are always welcome.
You can get thinkwatt from my git repository here or the AUR here.
