How much energy does an iMac uses in volts? (regular and when it is asleep)

How much energy does an imac uses

The voltage during sleep or usage is the same. It's the current in Amperes that changes. The "energy" is the wattage consumed which is Volts times Amperes. That information should be in the User Guide. If you don't have one you can download one here.
According to the specifications the rated power consumption is 200 watts for the 20" model and 280 watts for the 24" model. Sleep consumption is probably around 40 watts.

How much power does the iMac use at idle? (e.g. in watts)

I've just noted how much my current PC chews up in power - wondering how good an iMac would be?

How much data does google maps use

how much data does google maos use ?

That question has a lot of variables. If you are just looking up an address it should not using very much. If you are using it for an 8 hour drive it will use quite a bit.

How much energy does a "brick" power cord take?

Hi,
1. How much energy does the White Brick power cord consume when the computer is fully charged?
     A. Does it vary based on processor action?
     B. How bout when the computer is sleeping?
     C. How bout when the computer is off?
2. How much energy does it consume when it's not attached to the computer?
     A. I also want to know this for chargers for other Apple devices.
Thanks for any info on this. I haven't done any searching on this, so maybe it's an obvious question.

Thanks for these answers. I neglected this post for a while as I didn't have time to investigate. The answers were helpful.
I did find some more information:
https://discussions.apple.com/message/6423752#6423752 lists (for a 2008 macbook) the consumption. I would be interested in seeing this for the latest models. Especially interesting is this: "Power brick energized, but not attached to computer - unmeasurable." Is the power adpater (it's a transformer) this energy efficient? This is a big deal if I am planning on unplugging my laptop at night.
I also see this: https://www.apple.com/macbook-pro/environment/ . But, unfortunately (and outrageously), it does not give details (it is not outrageous as a status quo piece of marketing, but it's outrageous that the status quo is that little information! So, the problem is not Apple, per se, but the habits. Maybe that is an area for a marketing company to improve on!
I found this for some more, general information: http://electronics.howstuffworks.com/everyday-tech/plug-in-transformer.htm . That gives: "The power consumption is not large [on power chargers] -- on the order of 1 to 5 watts per transformer."
I'd certainly be interested in information on Apple's other products (like iPod and iPhone chargers).

How much data does Apple TV use?

I am experiencing a large amount of data usage and cannot determine what the culprit is. I am approaching my cap of data allowance on a regular basis. Does anyone know how much data the Apple TV uses? I realize it depends on what you are streaming. I primarily stream Netflix (set on the lowest data rate)
Thanks

I found this answer on NetFlix's blog sometime last year:
In the USA you have 3 video quality options: good quality, better quality, and best quality. Here is how much bandwidth they each use:
Good quality (up to 0.3 GB per hour)
Better quality (up to 0.7 GB per hour)
Best quality (up to 1 GB per hour, or up to 2.3 GB per hour for HD)
Depending on how many movies you watch this could have a huge impact on your monthly usage...obviously your ISP wants you to watch its own movies.

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 data does a call use over 3G?

Does anyone know how much data a call uses when using 3G?
For example if I made a 10min call over 3G is there an easy way to estimate how much data it would use?

I'd check my balance, make a call, then check the balance again. That should give a fair indication.
I'm a light user and find Tesco's SIM-only deal (500mins, 500MB, 500texts) is way more than adequate for my basic mobile needs for a tenner a month. Worth considering.

How much spaces does an iMac need?

I live in a condo in Japan and physical space is limited.
How much physcial space do I need for an iMac?
I have a desk in a spare room where it would fit perfect, but we don't have central heating (Japan generally doesn't have it) so in winter that room is not heated and the daily temperature hovers around 30 degrees Farenheit.
In our heated living/dining room I have a tea cart that is 15 x 24 inches, but I'm not sure if that is big enough.
Another option would be that in winter to move the computer from the spare room to the dining room table every time I wish to use the computer, but that seems a little weird and I would hate to drop it along the way.
I have my eye on either the 17-inch iMac, upgraded 2.16 Ghz, upgraded 2 GB memory, and upgraded 250 GB hard drive.
or
the 20-inch iMac, 2.16 Ghz, upgraded 2 GB memory and 250 GB hard drive, both with wireless keyboard and remote.
I thank you in advance for your suggestions.

The iMac is about as compact as you can get in a desktop computer. It basically takes up the same amount of space as a monitor of the same size. Of course, you also need a place to put the keyboard and mouse, but the iMac itself isn't very big.
If your tea cart isn't big enough, you might consider buying or building a small table for the iMac. There is at least one company that sells a desk made specifically for the iMac, and it's rather compact (http://www.raindesigninc.com/igo.html)
I wish I was back in Japan. I lived there for a fair while, but came back to the states two years ago. Didn't have a Mac in Japan though.

How much data does Assisted GPS use

Guys
I'm planning a trip into Europe, we will of course be taking a TomTom, but in the event that I need OVI maps, could you tell me how much data AGPS uses.
O2 charge £6.00 per mb, so I don't want to come home and find a massive bill waiting for me.

Usually when I try to use it, I use about 6-15mb per fix. It doesnt use A-GPS again after getting a fix unless satellite signals fail.

How much space does IOS 6 use vs IOS 5.1.1

I upgraded my iPhone 4S to IOS 6 yesterday. Today, I was telling a friend about it and she said she doesn't have enough free space to install it on her 8GB iPhone 4. This got me thinking that with all the upgrades, how much more space does IOS6 require vs IOS5.X.X. Does anyone know?

Bit of a strange one, the file itself was 650-something MB, but when it came to install, it required me to have at least 2.5GB free space. When it was installed though, there was no change in the free space on my iphone. So, its a mystery.

OK, So How Much RAM Does Photoshop CS5 Use?

ANSWER: All you give it, lol!
I posted this for those buying or building a PC and are deciding "how much RAM do I need?"
I built a fairly powerful rig for Photoshop and editing in Premiere Pro, and without all the tech specs, I have 24GB of ram, mostly for encoding HiDef video. Surely Photoshop wouldn't eat THAT much, right? Dead wrong. I have Photoshop set to utilize 75% of my available ram which would be near 19GB. I just worked on a fairly large image, where I took 23 vertical shots with my 5D Mark II (5616x3744 resolution files, pretty big) and did a large photomerge which ended up at about 60,000 x 5,500 after the crop. Granted, large image, nearly 3½GB .PSB file. So while the merging and aligning was taking place, I watched my Ram Gadget soar, right up to 19GB within 4 minutes of processing:
Yowza. I expected that from Media Encoder processing 1080p HD video into a Blu-Ray disc format, but not a Photoshop file. So, the point of all this: ram is lower in cost than it's been in many months, a 12GB Mushkin kit (3x4GB) is down to $169 on Newegg. Don't skimp in that arena, fill 'er up as best as you can. Future versions aren't going to use less ram, let's face it, the software has to process a lot of pixels! Try to go a minimum of 6GB, but definitely 8-12GB if you can. Of course this means bye-bye FINALLY to 32-bit operating systems, but once you have a large playground of memory, you and Photoshop will be happy campers.

I purposely waited to respond so I wouldn't write things I'd regret later:
"Nice system."
Huh? I didn't list my system on purpose. The point wasn't showing off gear, it was PS's use of RAM.
"With regard to RAM and Photoshop, people often say more is better without qualification, and you have just confirmed that advice."
You actually have no evidence of my qualifications. I'll send you a link to my Microsoft transcript if you'd like, there are 16 certifications you can peruse.
"Personally, with 24 GB of RAM I'd suggest settting Photoshop's limit even higher - e.g., to 95% (which is what I use for 8 GB) ... The OS doesn't need much on that scale."
24GB x 95% = 22.,8GB... that leaves 1.2GB of RAM for everything else including Windows 7 64 bit. I'm sorry, that's an extremely unwise choice. Noel, maybe you need to remove the "unqualified" beam from your own eye before you point it out in others.
If anyone is reading this please PLEASE don't set your Photoshop limit to 95% of your available ram. Your system will mostly likely crash within minutes of starting Photoshop. The proven setting is 75%, set it there and move on. Thanks.

How much data does Apple Maps use?

I used maps for 15-20 minutes and it used 300 MB of network data. Looking for an answer because I only get 2GB per month and I wasted almost 20% of it in less than a half hour.

I guess it is possible I had satellite view on. I just used whatever was default and I got that huge data charge. I have just been avoiding maps since and using everything else normally so it has to be maps that was my big problem. Thanks for the response!
