Replacement PSU for an ADSL Router

  1. Sorry this is slightly off topic but I believe the expertise resides in this
    group to assist.

    The PSU of my 3com ADSL router has failed and 3com are being less than
    helpful in providing a replacement under waranty. The PSU output is rated
    12VDC, 1000ma. I have obtained a replacement PSU also rated as 12VDC 1000ma
    and am measuring the open circuit (no load) voltage as 16.8VDC. I have
    measured the open circiut voltage of the 12VDC PSU of a colleagues Belkin
    router as 12.1VDC. The question is can I use the replacement PSU (open
    circuit voltage 16.8VDC) without damaging the ADSL router?

    I assume the voltage of this PSU will be 12VDC when on load, is this a
    reasonable assumption?

    I will appreciate your advice.
