Service Action to Prevent PSU Failures in ReadyNAS NV/NV+

I actually purchased the same power supply and modified it like you did. After making the appropriate pin changes (I have a molex tool for that), I modified the cover over the fan to allow the cables to come through over the middle of the power supply.

I first cut the wire ties on the power supply cable bundles (allows it to flatten out), then I removed the bracket on the power supply that covers the fan (has some foam material on it). I bent the top back and forth until it snapped off and then put some tape over the rough edge that is remaining. I re-installed the bracket so that it secures the power supply correctly. The power cable will just barely fit (flatten out the cables). I would suggest plugging in the power supply before mounting the bottom to the RN unit.

It will be just a bit tight but will go together just fine.

PM me if you have any questions or would like any help.
