ReadyNas RNR4000 Power supply failure

Hello,

 

Can anyone help with locating a replacement Power Supply for my ReadyNas 1100 - RNR4000? 

 

The power supply did not survive a power failure even though it was connected to a UPC.  With that I sent it out for service.  I was told it would be cost effective to purchase a new Power supply instead.  But unfortunately, my ReadyNas 1100 was returned missing the original Power Supply...they lost my power supply.

 

Can anyone direct me as to how to decifer what power supply was in this unit?  Or how and where I can cross reference for a compatiable Power supply?

 

Thank you in Advance.

  • I think I found the right one.

     

    I've never had an 1100 to work with, but believe its power supply does have the small rear-facing fan pictured, so that supply should be good for it.  On the other hand, most of the other models listed have no place for the fan to exhaust, so it's not a good choice.

     

    I guess the only questions are whether the picture showing the fan is accurate (that company makes a lot of supplies, and it could be the wrong photo) and if the fan has been disabled to make it more compatible with the listed units (though it would still not have proper airflow for them).

     

    The one listed as "NEW 350W Netgear ReadyNAS NV 1100 RNR4450-100NAS power supply Replacement N1" would seem a safer bet, even though the picture is the same.  All of those models do have an outlet for the rear-facing fan *though later NV's shipped with (or were offered a replacement) fanless supply.

     

    It is just a slightly differently wired Flex ATX supply, by the way.  You can find the pin-out here: ReadyNAS_PSU_pinout .

  • It's the same PSU that is used in the NV+.

        good.  Maybe wait a bit, and see if Sandshark has any advice to offer.
