Mobile Gaming Deluxe. The Schenker XMG C703 is yet another version of the MSI GS70 barebone to come on the market. The notebook's appeal stems partly from the fact that you can select from a variety of configuration options when you purchase the device from the retailer. Equipped with an Intel Core i7 4700HQ processor, a Geforce GTX 765M and a thin, light case, the notebook debuts in the mobile arena.

I noticed myself ,using the hwmonitor that the power consumption on idle, at brightness level 50% was 0.8-1.3 watts, while, off the charger...
Earlier on, I had noticed on the idle consumption while on the charger at the levels you described around 8 watts...
While on win8.1, power saver profile...(primary ssd)
While the 6hour idle(pdf reading) sounds about right, saying that it consumes 8 watts is false.
Please either retest or put it as a note...
The reason I commented is that i, somewhere around the notebookcheck, read a comment where one was discouraged by the idle consumption...
