I’ve tested the power consumption of a couple more typical University desktop PCs. I also had some feedback on the shocking 9W consumed by the Viglen Genie I tested while it was ‘switched off’. More recent Viglens only use a much more reasonable 2W while switched off/asleep, which just shows the advances made in motherboard and power supply design. The older Viglens will of course get replaced in a couple of years, but until then we will have to live with their inefficiency .
|System||Switched off||Sleep mode||In use||Screens off|
|Viglen Genie desktop (old)||9W||9W||90W||47W|
|Viglen Genie desktop (new)||2W||2W||90W||45W|
|Dell Latitude E4210 laptop
(2 19″ screens)
|Dell Optiplex 760 desktop||2W||4W||80W||48W|
|Dell Optiplex 745 desktop||4W||4W||90W||45W|
|iMac desktop (27″ screen)||2W||2W||130W||90W|
If you want to test your own PC, you can borrow a power meter from the desk on Level 3 of the Hartley Library.
