Why do commercial SAS cabinets apparently draw so much power? (zerobytes.monster)

Looking at specs of older, data center quality expansion cabinets from companies such as Dell and HP, I see large current draw numbers, such as 7A at 120V for a 16 bay cabinet. Assuming each drive uses 10 watts max, that's only 160W. Add a few fans and 10% loss for power supply inefficiency, and you're still only looking at maybe 2-3A. Watt's going on here?

To be clear, I'm not talking about entire servers, these are only drive cabinets.
