Power Consumption & Noise
We used SeaSonic's Power Angel Power Meter to measure the amount of power our test system pulled from the wall. You'll find two figures below: peak power consumption under a full CPU/GPU load, and how much the system pulled from the wall when idle, following a fresh system boot.
Intel did a great job with balancing cooling and noise. As stated, our lockups were due to something funky going on with the wireless card, which Intel is in the process of fixing through a BIOS update. Otherwise, the system ran stable and was nearly silent, even under a full load. To hear the fan, you have to lean in real close, which is not something you're going to do under normal circumstances.
