PC Component Energy Efficiency a key to lower power bills

The draw of energy efficient PC gear is that it could, seemingly, cut off a large chunk of your energy bill given the fact that most PC enthusiasts leave their machines on a good portion of the day, if they’re turned off at all. Unfortunately for us all we don’t know what sort of energy savings you’re bound to see.

bit-tech has run a few tests on the more commonly available energy friendly PC hardware and the results are rather interesting:

We’re going to measure the real world differences between actual performance PCs. By measuring the power at the wall socket we have a direct readout of the immediate benefit provided by changing one component to a lower-power alternative, but it’s important to combine this with the time it takes to complete a computational task – a CPU that’s 1 per cent more power efficient when video encoding but that takes 50 per cent longer than its competitor isn’t going to be beneficial. From these two variables (power use and time taken), we can work out the product’s efficiency as a factor of power use over time.

Despite energy efficient hardware costing a bit more than the regular gear there are certainly plenty of choices in order to bring your system’s total power usage down to reasonable levels.
