Service Action to Prevent PSU Failures in ReadyNAS NV/NV+
A Service Action notice has been posted in the Announcement forum to prevent ReadyNAS NV and NV+ systems from premature power supply failures at viewtopic.php?t=10259. If you own a NV or NV+ within t...
My NV's PSU blew (ie, snap crackle, pop multiple capacitors) a week ago. I managed to find an identical Seventeam ST-FUB220-05E PSU. However, when I plugged it in, I got nothing. I noticed though the new PSU's plug wiring was slightly different from mine. Then I found this thread which confirms my suspicions:

So off I go trying to figure out how to pull out some ATX connector pins without the proper tools. It turns out, long header pins (such as https://www.sparkfun.com/products/10158) which you can get easily from your electronics store are perfect. So I used some needle nose pliers to stick two pins into each side of the ATX connector, then a little bit of wiggling, and out comes the connector.
As the above post said, pin 12 and 18 must be +12V. These can be found on the extra 12V connector (it has two black and two yellows, you want the two 12V yellows lines). So I plug the two yellows into pin 12 and 18. Connect the PSU to the NV's board, said a little prayer, and hit the power button. Oh I've never been so happy to see that glowing blue power light!
So anyway, the above is the good news.
The bad news is, as I start to reassemble the NV, I realize the original PSU has one additional difference: cable length. The main ATX connector is approx 12 inch from the PSU. Where as on the otherwise identical new PSU, the connector is only maybe 8" or so. Anyway, so my NV is no longer this pretty thing that's all self contained, but at least I can power it on now and get files off it. I suppose I'll have to figure out some way of improving the aesthetics of it (either by extending the cable, or by making an adapter)
I hope this post helps others as the above post from long ago has helped me.
TL;DR: It is possible to replace the NV's PSU without purchasing the expensive and hard-to-find official part.
