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.

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!
k...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 does your DSL modem combo use?

How Much Power Is My Mac Book Pro Using?
How much much power is my mac book pro using when it is closed and the power chord is plugged in? This is bugging the crap out of me because my dad keep making me unplug once im done. He claims its costing 7 bucks a month. I think that is bogus (remember this is when the laptop is closed). anyone have any answers?
I guess you could look at the info printed on your power adapter. Normally you'll see the output voltage and current values. Multiplying the two together will give you the power consumption of the computer (in watts) while it's plugged in. For example my Macbook says "16.5V and 3.65A" so it's about 60 Watts. For a MB Pro, my bet is around 80w. Looks like your dad did do his math to come up with that 7 bucks a month,:), but the pre-assumption is that you had it on 24/7, which i doubt. If you dad bought this MBP for you, you might wanna ask him why would he care the mere $7 after spending about $2000 on the thing.:)

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 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)
ThanksI 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 the FIS2R drains?

short question: How much Power needs the 865PE NEO2 FIS2R with all onboard components enabled? What is the Max-Usage? Does anybody know this?

Hi,
thanks for your answer. But my question ist how many the Mobo consumes. Without the periphery!
Why do I want to know this?
My Machine:
- MSI 865PE NEO2 FIS2R (Bios 1.8)
- Zalman ZM400A-APF Power Supply (400W)
- 1 GB Dual Channel RAM ( 2 x Corsair TWINX512-3200CL2PRO in Slot 1/3) running at 2-3-3-6
- 2 x Samsung SP1604N as Raid 0 on IDE3
- 1 x Teac 516E DVD Rom
- 1 x LG GSA 4040b Multi DVD Writer
- 1 x Terratec Aureon Fun 5.1 (PCI Slot 3)
- 1 x ASUS Radeon 9800XT (AGP Slot)
Cause I got almost all information about my periphery I want to know what the Mobo with it's onboard components consumes. The Zalman 400W is one of the best PSU out there as THG said in a test. But are 400W enough to be stable under heavy stress? Most 450-500W PSU aren't delivering what they offer.
So what is the consumption of the Mobo itself with all onboard components turned on (Firewire, USB Ports....)
It should be possible to calculate a whole systemconsuption based on all information I have, or not?

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 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?
Thanks
MikeBit 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. -
