    :mad: hi everybody

    i was testing a PSU about one years old 300W with my multitester
    first no load on +12V line / with load my old DVD-Rom drive
    second no load +5V line / with load my old DVD-Rom drive

    here is a result:

    on +12V line no load my tester read 11.25V
    with load 11.64V

    on +5V line no load my tester read 5.31V
    with load 5.19V

    is it normal or this psu gets dying
    any suggest thanks

    Tolerances of 5% either way are considered acceptable. Both your voltages are within that tolerance.
