Will this work for the new quad-core iMacs? The maximum continuous power is rated at 365W for the 27 inch iMac.

I am wondering because the Technical Specs for this item says that the output power capacity: 257 W/450 VA. Does this mean that it won't provide enough power if the iMac is processing something requiring peak power?

    Good question! It is not that it won't run, you just won't get the rated 9 minutes of power during an outage, maybe more like 7... In my experience when a power outage occurs, either the power comes back on in a brief minute or two, or if not, you tire of hearing your UPS chirping its warning sound and have a chance to safely shut down your computer well before the battery backup is drained. Hope this helps.

  • This is inadequate. However, Id avoid the Back UPS and go with a PFC friendlier UPS that outputs a pure sine wave like the pricier, louder, but reliable APC smart ups or the new less expensive cyberpower PFC friendly CP1000PFCLCD that doesnt use a pure sine wave, but will work well with a PFC powersupply.
