After seeing a deal on a 500w EarthWatts power supply, the hippie in me decided to make the purchase and save the world. Curious as to how much less power an 80Plus certified power supply would draw, I checked the UPS reading for this server and noted 174 watts. I then swapped out my standard boring power supply with the new exciting hippie supply (it's actually colored green) and was shocked to see it required 24 fewer watts to run the exact same equipment. That's a savings of 210.24 kWh per year at 6¢/kWh which means my $40 upgrade will save me $12.61 a year with a full ROI in 3.1 years. Definitely not a wise investment, but satisfies your inner hippie as long as you don't toss the old supply in a landfill.User Comments for 08-25-2007:
 | In 4 years it will be paying for itself! To bad the Moores law on powersupplys predicts that we will require 1000Watts by then... Do you notice if your videocard or processor are starving for power? Senator Kelley |
 | I completely offset your savings by using approximately 40 amps for my computer. brian |
 | Just to make sure Brad doesn't unbalance the world with his power savings, I left my 2nd computer online all weekend -- if power supplies were cars this thing would be like strapping two Hummer's together... E1 |
