Horsepower and watts have nothing in common, but for the fact that they measure the same thing (rate of energy conversion). Depending on the definition, one horsepower can be equivalent to anywhere from 735.5 to 9809.5W.

Because no energy is lost to friction with electronic devices, the 95W part at full tilt will draw and generate 95W of heat; the 65W part will draw and generate 65W of heat.
