Power Supply Replacement ReadyNAS NV+

Hey there,

I just had a power supply failure on my Infrant ReadyNAS NV+ this morning.  It's pretty much a standard ATX power supply connector but it has yellow +12v wires at pins 12 and 18 (replacing the blue -12v and the empty slot).  

Anyway, I modded a standard ATX power supply to replicate this configuration and it's up and running and I'm pulling important stuff off of it right now.

I have a small form factor ATX power supply from an old IBM NetVista that I think would fit perfectly as a replacement for the original power supply but (there's always a but) it doesn't have the brown 3.3v DC sense wire.  The original PSU and the PSU I've got rigged up to it right now both have that.

SO - what happens if I connect the PSU without the brown sense wire and is there anything I can do to rig it if it's absolutely required?

TIA

Newer or more expensive power supplies use the brown line to monitor voltage regulation on the +3.3v line. If your IBM power supply doesn't have that line, it means it doesn't need it / use it.

This might be a sign that it is a lower quality power supply, but it shouldn't affect your NAS. I don't think you'll run into any problems if you use it.
