Check Your PC Power Supply's Efficiency Rating To Help Reduce Your Power Bill

Video: If you're building a killer PC gaming rig, you might need a high wattage power supply. However, some power supplies waste more power than others. Here's how to find out where yours sits. This video, from Linus Tech Tips, demonstrates how much electricity different power supplies draw from the wall, which is to say not much. Most higher wattage power supplies don't draw a significantly higher amount of power than lower wattage units.

However, the load you place on the power supply can have a more significant effect. A lower wattage power supply might start getting less efficient when you approach 100 per cent of the load that power supply can handle. This means that using 100 per cent of a lower wattage power supply may waste more electricity than using 50 per cent of a higher wattage unit's load capacity. Check out the full video for more details on how to build your rig to be as power efficient as possible and hopefully shave a little off your power bill.


    I did the maths on this one, the price difference to jump from a Bronze to a Gold would have taken over 3 years to recoup in savings off the power bill. The savings are marginal at best...

      Electrical savings are one thing, build quality is another completely. My Thermaltake Toughpower PSU that I bought back in 2006 is still kicking along quite happily since I took that machine apart for parts for my HTPC. Those things have been built to last.

        There's no difference between build quality of a gold and bronze, I've been using the same bronze power supply for a good 5 years now.
