The Numbers
Firing up folding at home brings my (60gb) PS3’s power consumption to an eyebrow raising 234 watts. This is in the same league as many high end gaming PCs. When the screensaver kicks in, that number drops to about 215 watts. With screensaver on or off, the draw is very consistent so calculations can be extrapolated from these two simple numbers. So without further adu, let’s do some math.
234 watts of constant draw is 0.234 kWh per hour. So, if ran for 24 hours straight a PS3 folding without the screensaver would draw 5.616 kWh (0.234 x 24).
5.616 kWh a day x 31 days = 174.096 kWh a month x 23 cents per kWh = $40.04
Thats right; $40 a month is the worst case scenario based on my power rates. I don’t think I need to tell you that that is no insignificant amount of money. Let’s run the screensaver numbers.
5.16 x 31 = 159.96 x 23 = $36.79
