    Default Power Supply Input Voltage

    Hi,

    I am very curious as to how much difference input voltage makes to a power supply's performance and efficiency.

    Given most modern supplies support 100-240v in, is there any difference when running at 110v vs 240v?

    Thanks,

    Josh

    Yeah, power supplies are more efficient when running on 220v .. 240v.

    Cool. I always did wonder. We get 240v here in Australia, that's handy.

    It depends: for instance, some PSUs are more efficient at low loads on 115V voltages (while feeding them @ 230V usually boasts high loads efficiency).
