MSI 3PF9

At the standardized usage ENERGY STAR assumes, the MSI 3PF9 consumes 87 kWh a year — about $16 at the U.S. average electricity rate ($1.37 a month). It sits near the bottom of the certified table — using 94% more than the median computer monitor (rank 1301 of 1482) — so the state you live in matters more than usual. The same unit costs $11 a year in North Dakota but $41 in Hawaii — electricity rates, not the appliance, make the difference.
