Well I'm running a Dell Poweredge T110 ii / Intel Xeon e3 1240 v2 @ 3.4Ghz and only sipping an amazing 68W of power Maxed out while running 8 threads which I consider to be very energy efficient 5 years ago a chip like this would consume that much power at idle!. The onboard graphics Matrox eWG200 8mb of vram is very bad but I guess this is an intentional design factor where energy efficiency is the No 1 priority I think it only consumes about 4W of power for the graphics. This is meant for a small business server very quiet and energy efficient no onboard sound either lol probably total power consumption from the wall socket is approx 100W! seen a youtube video of someone testing this machine with a watt meter installed.
