24inch 2.8GHz iMac Power Consumption

I am planning out a new computer setup and need to make my UPS plans. Does anyone know the wattage of the 24inch 2.8GHz iMac? I need to make sure I get a UPS that provides enough. I asked the apple customer support and they said that information was unavailable. That makes it sound like they don't believe in an UPS protecting the computer from power losses. Any help would be greatly appreciated. Thanks.

This post is caveated that I don't know how accurate my power meter is but it is pretty new. 
iMac 2.8GHz
Off ~ 17.5W
Sleep ~ 16W
During boot ~ between 30 and 180W
Mail, Office and printing ~ 110W
EyeTV encoding H.264 (processor at 160%) ~ 135W (I also loaded every app in the Dock to get the processor to 200% without any real change in this figure.)
Idle - 105W
So my figures at least are significantly lower than the quoted maximum. It depends on whether you're buying a UPS purely to give you time to shut down or if you may wish to work for some time too.
cheers

  • HT3559 iMac power consumption

    Where can i find the power consumption level of my Imac (21.5 inch late 2009) when it is in sleep mode.
    It doesn't seem to include sleep mode here:

    I have seen it in the past in the enviromental report but that doesn't seem to be online for the 2009 model anymore?
    Thanks

  • Power Consumption for iMac 20" INTEL DUO CORE

    I need to know which is the power consumption for the 20" 2.16 GHz INTEL CORE DUO. I want to buy a UPS for this machine and I could not figure out in any place within the manual where to get that information. It is something that have to be very easy to find but it was not the case for me in this opportunity.
    I cannot believe that I have to create a post in order to get this answer!
    Kind regards to all and thanks for any clue that any one can give me.

  • Power consumption when PowerOFF: 24" iMac 2009

    I really wonder about my iMac 2009 Modell: when using sleep mode I got 11-12 watts power consumption. But when shutting down the iMac (Power Off in Apple Menu), the same iMac takes 10 watts
    Is this normal and how can I get sleep mode with far less or none watts?

    I'm having the same thing with my 2008 24 inch iMac. I'm not sure if it is the hard drive or one of the fans, but there is a loud WHOOSH every time it starts up or wakes from sleep and the whirring noise is pretty much constant. It used to be completely silent, so this new sound is very noticeable.
    Lately, the noise with abruptly stop and then make a struggling sound as if whatever is causing it is either going away or making it stop revolving or whatever (it would help if I could determine exactly WHAT is making the noise). I check iStat, but can't see any wide variance in the fans rpm speeds when it is happening or the heat of various components spiking. It is not affecting my computer use as it did the first time I had a similar problem (which turned out to the the hard drive, since replaced under warranty).
    I bought Apple Care for this computer, so it is still covered under that, but I don't know if the fact that the noise is completely annoying to listen to all day is enough reason to bring it in for service and be covered under the extended warranty.

  • Power consumption of the iMac 2007

    Hello!
    I found at this website: http://www.apple.com/environment/reports/ the reports also for older models of the iMac, but not for mine.
    Can someone eventual tell me the power consumption of the iMac 2007 24" in standby- ond off-mode? Or is there an older report from Apple available somewhere?
    Best Regards!

    It's going to fall somewhere between the idle of 92W and the maximum of 310W.  I would aim at around 210-230W.
    I run mine on a APC 1500 pro which provides about 15 minutes at 400W.  I have other devices on it as well.
    I would think at a minimum something like below.  This would only provide about 8 Minutes at 300W

  • IMac G4/700 Power consumption

    New question on an old but reliable machine:
    Lately my UPS has given an "overload" signal several times. It is supposed to handle 350 VA/200W.
    I searched through this forum and could not find a thread indicating where to find the rated power consumption of my iMac G4/700.
    Since this problem only started occurring recently I suspect my UPS battery is bad but I thought I would try to research all possibilities. Thanks for any help.

    When shopping for a replacement battery for the UPS, also consider
    the newer technologies in the higher model line of UPS products that
    have an 'automatic voltage regulation' feature. This will help keep the
    attached computer healthy and protect it from both Up & Down action
    on the grid. Also, some have a special USB-Ethernet data cable for
    use with the uninterruptible power supply that Mac OS X can then use
    to see and control the backup power configuration within System Prefs.
    The UPS, beeping, may also mean that during the weather and holiday
    seasonal loads on the grid, there are localized changes in the quality &
    availability of electricity in your area. My newer APC brand UPS is OK
    in that it shows the power specifications on an LED display on it, and
    also allows me to set power settings in the Energy preference panel.
    And it has a bigger battery, better technologies than my old failed one.
    Sometimes warehouse stores have a fair price on these, since shipping
    is generally high from elsewhere, due to the weight of the battery's lead.
    Good luck & happy computing!

  • HT3559 iMac 20" 2008 power consumption off, sleep, idle?

  • IMac (Retina 5K) power consumption

    At what wattage is the iMac 5k (4.0 GHz) rated?
    I've ordered one, but want to properly spec out a UPS for it and my peripheral devices.
    The only tech specs I can find regarding power consumption are:
    Electrical and Operating Requirements
    Line voltage: 100-240V AC
    Frequency: 50Hz to 60Hz, single phase
    Operating temperature: 50° to 95° F (10° to 35° C)
    Relative humidity: 5% to 95% noncondensing
    Operating altitude: tested up to 10,000 feet
    (Ref: iMac (Retina 5K, 27-inch, Late 2014) - Technical Specifications)

    Drill down in the Tech Specs link to the Environmental Report.  ~72W at idle.

  • Max power consumption 2011 iMac 27"?

    What's the total maximum power draw of a 2011 iMac 27" with 3.4GHz Core i7, 16GB RAM, 250GB SSD + 2TB HD?
    This is so I can properly size a replacement UPS.
    The Apple environmental report doesn't address this: the closest it comes is the idle power consumption with display on.

    Thanks for that rule-of-thumb!
    Actually I have a maxed-out iMac (not a Mac Pro) -- as you'll see in my profile, a BTO with max speed Core i7, max RAM, also a 2GB VRAM. Both from greater eneregy efficiency of latest processors, I assume that without question a current iMac would in fact draw less than an existing Mac Pro.
    I have an APC Back-UPS RS 1500, aka model BR1500LCD. Its battery is nearly at the normal age for replacement, so I'm considering the APC "trade-ups" program. Ideally, I'd get as replacement:
       Back-UPS Pro 1500 (865 W, 1500 VA)
    Unfortunately, that's several inches too high to fit under my computer table, so that's out. That would seem to leave:
       Back-UPS Pro 1000 (600 W, 1000 VA)
    With Apple's Environmental Report showing idle-display on consumption, at 115 V, as 143 W, the latter 600 W model would seem to fall within your rule-of-thumb recommendation, and even if I'm also running an external HD for backup that I want to let stop gracefully in the event of an outage.

  • Power consumption for 7100?

    Hi:
    Does anybody know what is the power consumption of the 7100 series device in the 'idle'  mode and 'call' mode?
    Can not seem to find this information....
    Thank you

  • Power consumption for latest mac pros?

    I read on Apple.com somewhere that the 2008 Mac pro's maximum power consumption is 260+ Watts for a Quad-core. How different is it for the new Mac pros?

    I guess English is a lost language now.
    For the Mac Pro it is really really simple and based on 7 yrs of PowerMac G5s and then Mac Pro owners: 1500VA - you can get by with slightly smaller 1300VA and some people, because of better build, used SMART UPS 1000VA.
    And as I said in another thread, the Mac Pro 'suffers' from inrush current that can knock out smaller UPS, and people that have tried to use 500-900VA units got into a lot of trouble and had to upgrade.
    No one can know the total system watts used other than use a KILLAWATT on the power cord.
    Look at the case, can an iMac dispel as much heat as easily? no. It is designed for lower power and much fewer components.
    Core i7 has HyperTransport and Turbo boost for one thing. Apple had a huge coding problem with audio (incl iTunes and others), flash and Nehalem based systems. High cpu temperature and lost processor cycles and performance.
    The 2010 Mac Pro can do more for the same, and DDR3 lowered heat and watts noticeably.
    There are sites where you can plug in various components and get an idea of how large a PSU would be needed. Try one of those, too. PSU efficiency, and there is "overhead" needed for the motherboard chips and to run PCI Express for graphics, Firewire, etc. It all adds up.
    Apple's example is low-end system configuration, the chart says CPU MAX, not SYSTEM (but then, most everything on hardware requirements lately needs a grain of salt).
    Quad-core 2.66GHz configuration:
    One 2.66GHz Quad-Core Intel Xeon "Nehalem" 3500 series processor,
    3GB memory (three 1GB 1066MHz DDR3 ECC DIMMs),
    640 GB Serial ATA 3 Gb/s 7200-rpm hard drive,
    18x double-layer SuperDrive,
    NVIDIA GeForce GT 120 with 512MB of GDDR3 memory
    APC we know, whether PowerMac 2.0DP from 2003 or Quad G5, or Mac Pro, that 1500VA is strongly recommended.

  • Low Power Consumption Thumb Drives (For Aluminum Keyboards)

    Like most folks without an iMac (I have a MacPro), I'd like to plug a thumb drive into the side of the keyboard. But with most of the drives I have I get the "Low Power Notice".
    However, when I plug in an older SanDisk Cruzer Titanium, it works great. The drag is it's only 512MB.
    Does anyone know of lower power consumption thumb drives that will work with the aluminum keyboards?
    Thanks!

    OK, are you plugging your keyboard directly into your MacBook Pro with the notebook plugged in or running on battery? It seems like the keyboard is not receiving enough power or is defective so you just need to narrow down where the issue is.
    My guess is the keyboard is not getting enough power so it in turn cannot power external devices. You might try taking it into an Apple store and speaking to a Genius. If you can't try another keyboard and see how that performs, if you get the same issue then it's not the keyboard it is probably the amount of power being supplied to it.

  • Intel iMac Power / Overheat issue?

    Hi there,
    I have an Intel iMac from 2006. About 2 years ago it started to just turn itself off randomly as if there was a power failure. When it does, the only way to power it back up is to switch it off at the plug, switch it back on and press the power button (strangely) twice. I have noticed it seems to be temperature related - when my iMac reaches around 78C (which I'm pretty sure it should be able to handle fine?) it tends to be in the danger zone and at any minute can switch itself off.
    I've got around this by using smcFan Control - which thankfully displays the temperature in the menu bar meaning when I hit around 72C I can whack the fans up to full blast to keep the temperature down. Being a sound studio computer - the hum of the fans really isn't ideal, but it at least makes my computer usable. However, I'm currently in the middle of a big project on Logic and I've had to turn my room into a fridge (window open-more clothes on) to be able to work on it as all the processing involved heats it up to 75C+ in no time.
    I was hoping someone could shed some light on this or at least tell me if I am right in thinking that 78C is nothing really and the iMac should deal with it easily.
    I have seen tons of posts regarding the G5 iMac power problems and similar problems with the intel iMacs - I've done all the hardware resets (PRAM, SMC, PMU) as suggested in these forums but nothing has helped.
    I have had the power supply changed in the past (before this problem arose) as one day it just went kaput. Don't know if that makes any difference but I'm pretty sure that the problem started a little while after the replacement was installed.
    Thanks in advance!

  • Is there a way to adjust the bass and treble on my iMac Power PC sound system?

    Is there a way to adjust the bass and treble on my iMac Power PC G5 sound system? It has a lot of volume (more than my JBL speakers).

    No, but iTunes has an Equaliser that enables you to do that.
