The Beebox consumed just 6 watts at idle with a 2TB 2.5" hard drive, 16GB of DDR3 memory and the 128GB SSD installed. Taking all that into consideration, using just 2 watts more than the ECS Liva X the Beebox is extremely efficient.
With both cores at a constant 100% load the Beebox consumed just 9 watts, which was just 3 watts more than the LivaX but 8 watts less than the Asrock N3050-ITX motherboard and 28 watts less than the Sempron 3850 system.
With the CPU and GPU under full load the Beebox consumed no more than 14 watts, nearly half that of the Asrock N3050-ITX.
