How much power is used by a sleeping Mac?

My power company sent me an email about "vampire power" used by a sleeping computer, and the estimate that the total is roughly $79.98 per year per computer, if the computer sleeps vs. being manually shut down. Is this true of an IMAC?

Does that estimate sound accurate?
That number seems wildy high. I just measured the wattage used for various statres on a 20" iMac (7,1)
     Startup = 70 Watts
     Running = 90 - 105 watts, depending on activity
     Sleep = 1 Watt
At a usage of 1 watt, it would take 1000 hours for 1kWh (standard measurement of electricty usage). I'm not sure what the rates are in your area, but for my area (about 13 cents/kWh) it would use about $1.17 per year, assuming it was sleeping for that time.

How much power does a Mac use when it's sleeping

I recently asked about shutting down vs. sleeping a computer at night. Now I'm wondering how much power it uses sleeeping. I have a laptop which I imagine is pretty dormant. What about a desktop-- Intel Mac?

I can tell you nothing about a laptop as I don't see a way of measuring what it's using while asleep. As for the desktop you are pretty much spot on, You can use it for about 11 times longer than a 100W light bulb for the same money.
In fact by using one of those price comparison websites I work out that it'd cost, (@ 10.17p/KWH), [24x365] x 0.009 x 0.1017 = £8.018 if it was left on standby all the time for a full year.
That excludes things like a standing charge for the electricity, and assumes you were on the Fixed S@ver Dual Fuel plan from EDF Energy.

How much power do iMacs use when working and asleep?

As usual, whilst claiming green credentials, the information Apple gives regarding power use is minimal and vague to the point of being meaningless.
The only figures they quote are:-
Maximum continuous use 205w (21.5") and 310w (27")
What exactly does maximum continuous use mean ?
a. When the machine is switched on but not doing anything
b. Working at general office tasks
c. Working flat out transcoding video etc.
Which of these is it? Or is it all 3?
Does it use more power when performing harder tasks?
If so, what power is used under scenarios a and b?
Finally, how much power is used in sleep mode?

Apple, nor any other device, apple or otherwise, isn't going to give you every power draw for every possible scenario. So they post what the maximum power would be under maximum load (graphics intensive, computations utilizing all the cores, etc.). That would be useful for estimating, say, what UPS to choose for the machine.
You want various power draws under various conditions then attach a wattmeter or a KiloWatt EZ.
Why are these details significant?
As for sleep, I found the following (reference):

How much power is Sleep Mode using?

I use my PBG4 as a desktop, with the power plugged in. I love using sleep mode so it'll come back on almost instantly, but I'm wondering how much power I'm actually using (read: "wasting").
Is it so miniscule that my environmentalist conscience can justify leaving it in sleep mode overnight? Inquiring minds want to know.
/tw

According to this Apple PDF: Apple Product Environmental Specification - Powerbook G4 12", the PB draws about 3W while asleep and plugged in, about 20W when awake and idle and about 2W when turned off and plugged in (battery charging).

How much power does your DSL modem combo use?

My Westell-F90-610015-06 according to my Kill A Watt EZ uses 5.4-5.6 va @ 2.6-2.8 watts @ 0.04 amps

G4 - how much power does it use?

How does the computer use power? It's not like a heavy duty motor in a refrigerator, a shop vac., heater or power tools...
How much power does a powermac G4 consume, on average...in terms of dollars added to a monthly bill? I see on the back of the Mac that it's rated at 6 to 8 amps, but I can't understand how it can suck up that much electricity when all I hear is the fan, basically.
I use it for video editing, so if remove internet, and most other programs that might use power, except for apps needed for video, photoshop and text edit, would I save at all?
thanks!

...so if remove internet, and most other programs that might use power, except for apps needed for video, photoshop and text edit, would I save at all?
Hardware, not software, uses power. One heavy-duty program may demand more of the hardware than another but most--pro audio/video editing and some 3D games excepted--never force the hardware to work up a sweat on modern machines.
There is a current tester that clamps around the main power cord of anything electrical to read power consumption. I can't find the link to it right but it is standard piece of kit for electricians. My appliance guy's tool bag has sported one as long as I've known him. If you REALLY need to find out hard numbers, that's the way to go; be aware that the tester I saw on the 'net was US$100--you could run a G4 a long time for $100.

How much "power" will my VGA out give me?

I was just wondering, how much power the graphics card is on my iBook G3. I have used the TV out through the headphone jack, and it works ok, but very low quality. I see there is a mini-VGA out. For $20 - I can get an adapter that turns that port into a regular VGA plug that I can use with any other monitor.
This Black Friday, there is a place selling a 22" LCD monitor for only $139.99 which is super cheap - and I was wondering if it would work with my iBook. What I am concerned about is - this monitor had a native resolution of 1680 x 1050, and my iBook monitor is 1024 x 768. So, when I plug in this monitor, will that option become available, or will I be stuck with a 22" monitor with a stretched 1024 x 768 picture? If that is the case, then it's not worth it.
But I was just wondering what the max resolution was of the VGA out on these old iBooks.
Thanks!
Scott

I don't know about the Pro models. You may want to ask in their forums if you're considering buying one of them.
As a matter of fact, I'm not 100% certain about the MacBook since I've never actually tried connecting an external display and I don't often post or read topics in the MacBook forums. However, the question has come up many times here about the iBook G3 (Dual USB) (where I have been posting for over 5 years), and I'm sure that its resolution is fixed at the maximum of the built-in display. I based my comment about the MacBook on the assumption that since the MacBook is the iBook's replacement, there is a similar limitation. Pro models have several capabilities lacking on the consumer models, and I really don't know about the resolutions they may support.

How much power?

within the next few weeks, i will likely be making the move to the world of mac and subsequently, to logic pro. my only real big question at this point is just how much power will i need? i will definately be going with the intel processor but how many tracks can i work with at the 512mb minimum requirement or how much more ram would i want to upgrade to? i am currently looking into the imac or macbook due to price and mobility.

Buyig rams fr A vendor and not fr apple to use on A mac.
Is A real riskyie situation.
1 not all memory works on all mac.
whether it is DDR /SDR. Trust me.
Some macs will accept the memory but will not work properly.
why do you think loads of mac go crashing on logic when stuff is being process,
the time it take to get from 1 memory to the other it go CRASH CRASH.
Say you went back to the shop
LOCAL VENDOR.
NOT MAC.
They will tell you all type of RUBBISH some vender that is I had to make out like i am some real yard man ganster cause the boss man was,nt having it.
Wow lucky for me, for 1 of the first time IT fealt great. cause they see I was JAMAICAN and I was in no (ramping)/ meaning -PLAYING.
I WHEN AS FAR AS MAKING OUT LIKE I WOULD SMASH THE WHOLE SHOP IF THEY DID,NT SHORT
THE BAD MEMORY OUT, ITS NOT WORTH THE HASSLE.
EIGHTER GO TO APPLE.
ARE TAKE SOMEONE WITH EXPRIENCE ON MAC, AND IT WOULD ALSO BE BETTER TO TAKE A MAC WITH YOU THEN TEST THE MEMORY.
ONLY SOME MAC,S WILL PASS ON THE MEMORY CHECK, THOUGH.
BUT IF YOU CAN GET A DEAL AT A VENDOR A YOU ARE NEW TO MAC.
THEY CAN SEE YOU COMMING
YOU ARE IN TO BE PLAYED.

Buying a new iMac... how much power do I need to run GarageBand well?

Hi All
I am about to get a 27" iMac but am weighing up the options for the processor and memory (and maybe hard drive too). Neither my wife nor I are into gaming or high end graphics stuff, so we do not need an i7 with 16GB ram... but is the bassline 27" iMac powerful enough to run GarageBand with no problems?
I have not really used it much before as our laptop is about 6 years old and it really struggles running GB, hence I have not been keen. However as I am a musician and am about to get a new computer... I am keen to find out just how much power I'll need.
At this stage, I want to play around with GB and dop some aranging, not sure how many tracks this will end up equating to as my experience grows... but unless I really get into it, I am unlikely to progress to Logic or similar... but if I did, would I need more than the baseline?
So in short... do you guys think the 27" iMac i3 with 4GB RAM will cut it for someone who is getting started but wants to spend a reasonable amount of time in GB? Why/why not?
Thanks

In order to fully understand what you just said to me... I had better find out what an 'Addictive Drum AU' is. I am quite teh newbie when it comes to digitally recording, either from a real instrument or a virtual one.
I am assuming that the Addictive Drum is fairly intense when it comes to the CPU? Are there many other virtual instruments that are hard on the CPU? For an average user I am assuming this will not pop up to often, correct?
Garageband is not a 'closed system' in that you are stuck with what it offers. You have the option to use 3rd party software to enhance your productions. AU stands for Audio Unit, a coding standard around which many 3rd party developers use to integrate with Mac products. As you develop your own habits and tastes with your productions, you might decide that the options GB offers you are not to your liking. This is where these sorts of products come in. They are very easy to use with GB. Addictive Drums is a Drum program that is actually lightweight on your system compared to others. The only reason I had 8 instances (one loaded on 8 individual MIDI tracks) was because of a limitation GB has. It suited my workflow to do it this way.
There is a huge range of AU's available, Native Instruments being a company that does a very good set of products. Some are indeed very CPU intensive, others are not. You have to do your research by asking questions on various forums and seeking reviews etc.
The term 'Average User' really means nothing in my honest opinion. Depending on your preferred genre of music and how you go about hooking into this slippery slope of hobby home recording, you may bump into a variety of limitations either in GB itself or limitations because of your machine. Because RAM is easily replaced by the owner and hard drives are easily obtained for extra storage, CPU is the thing your are stuck with from day one. Programs are getting bigger and they are relying on lots of number crunching. Amp simulations are a good example of CPU intensive software. It is easy to find yourself spending $60 here and $99 there on all sorts of cool Software, and before you know it you have quite the quiver full. I am not a heavy GB user, in that I don't run 30+ tracks on my projects. I am a 12-16 track average user most of the time. However, the reason I upgraded to my iMac recently was because I had one piano AU, yes just one, that stopped my 2 year old macbook in its tracks when using another recording program. I had all the RAM that GB could use, an excellent hard drive and a very good sound card, but the computers lack of grunt made working with it tedious and sometimes frustrating. You more than likely have a budget to work with when getting your machine. The advice I would give any personal friend who was getting their first computer for recording is to get the most CPU you can for your budget. You could be staring at this machine for the next 4-6 years. Typically RAM and hard drives get cheaper over time should you need them, relatively small prices to pay in the long run.

How much power is supplied for the video card in the 2009 mac pro?

I am trying to find how much power is supplied by each six pin power point and the pci e slot on my 2009 Mac Pro

The first two slots can provide 75 watts each. 40 watts each for slots 3 and 4.
Each auxiliary 6-pin power connector can provide 75 watts.
You can't use all these at maximum at once, though. Total power is limited to 300 watts.

[915 Series] How much power?

How much power in watts does a MSI 915P Neo2 Platinum Motherboard + 3.2Ghz Procesor + 2GB DDR memory require?
I'm trying to find out how much power my system uses, I've seen a "350W Fanless PSU" but I'm not sure if 350W is enough to power my system.
I've looked on the MSI site but cannot find any mention of the power used by the motherboard itself.
Pete

+12v - 22A min
+3V - 30A min
+5V - 30A min
Watt rating > 400 (preferrably > 450).
Rule of thumb for a Prescott system. High end or dual cards, add extra amps to the +12V and consider watts > 500.

How much power is required from a USB port?

The 3rd gen Nano manual says that a "high-power USB port" is required (e.g., a un-powered USB hub won't work). If I buy a USB2 cardbus adapter (because my old laptop only has a USB 1 or 1.1 port), how much power is "high-power"?
D-Link sells such an adapter (DUB-C2) that says it has 500 ma per port. Is that enough power to charge Nano?

100mAmps is low power.
500mAmps is high power.

Is there a way to find out how much data was used over the lifetime of my phone (cumulative cellular and wifi)?

Is there a way to find out how much data was used over the lifetime of my phone (cumulative cellular and wifi)?
I was just curious

Given that the phone doesn't track how much data is used over WiFi, no. And cellular data usage can be reset.

Kernel Memory limits. How much can it usefully use?

I just wanted to check something.
Obviously the Linux kernel can handle a lot of memory, but the question is how much can it usefully use before it needs to be specially compiled?
I need to build a server to clean email, and because it is very very busy, (well the last one was and so is its stand in) it will need 4GB of RAM as an absolute minimum but I would like to put in 8. If I go for 8, do I need to rebuild the kernel?
Kind regards
Benedict White

If you install Arch64 and use the normal kernel package -- no. You won't touch the RAM limit for some decades to come.

How much data is used when using facetime over 4g

How much data is used when using facetime over 4g. Say a 10 min call over facetime, will it use few MB or more.
Thanks,

It depends on how long you are on line. What you could do is reset your data usage in settings/general/ usage and then start your FaceTime session and check usage after your session
