I would like to know roughly how much it costs to have my iMac stay turned on 24/7 with the display turned off? Its a 2011 3.4Ghz 240GB SSD 27" iMac. I would like to access photos/files/movies stored on the iMac via my iPad that's why I just leave the display on the iMac turned off, but the rest of the computer is still active. How much watts does it consume? I'd imagine a bit more than usual because the 3.4Ghz CPU is always running at 3.4Ghz? Or is there a way to put the CPU in a lower frequency sleep mode? I am thinking the SSD draws much less power than a traditional mechanical drive? I am thinking leaving the iMac on 24/7 is better than "shocking" the system by turning it on and off a few times in a day? I am worried about the capacitors or the power supply might be worn down unnecessarily by constantly turning it on and off. Thanks.
