Each C200 mines at 20GHash/s, consuming a mere 100W. Designed for high density operation, the C200 provides efficient movement of air and is suitable for operating in a fully loaded 42U rack (up to 40 units per rack)...When compared with GPU mining, the C200 consumes 100 times less electricity and 14 times less rack space, meaning there's virtually no operating cost associated with this device.
