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?
