How Much Electricity Does a PS4 Use?

Adding a PS4 to your household would increase your electricity bills by £22 to £32 per year assuming you play 2 hours per day, depending on the model and how you power down when the system is not in use. The more powerful Pro PS4 only increases annual electricity costs by £7 per year over the Standard model. As the systems use much more electricity during active gaming, those who play more will clearly have higher energy bills. To figure out your estimated electricity costs, simply adjust the numbers according to your play time (e.g., by playing 1 hour per day on average, your active gaming electricity charges would be half that of the numbers in the following table).
