That seems unusually high. Mines showing a peak 0.05-0.06A, 11-14W. I'm
using one of these to measure:

What make is the powersupply? What's the motherboard? My guess is that one
of those two is to blame.

On my machine copying a 4GB file from an SSD to a mirrored pair of SATA
drives added approximately 20W to the consumption. Pretty trivial in
comparison to the CPU or GPU.
