ReadyNAS nv+ won't power up after outage. Power Supply Problems?
Hello
My ReadyNAS NV+ (Product: ReadyNASRND4000, Serial Number: 23J3027700C11) was originally purchased in November 2010. In June 2016 I had a problem with the power supply: The NAS wouldn't start up following a power outage. I contacted Support (Case #01288820) and was sent a replacement power supply, even though at that time the warranty period was officially ended.
Now, exactly three years later, I'm having almost exactly the same problem. After a lightning strike that threw our main circuit breaker, the unit would not power on once mains power was restored, even though I pressed the power button several times. I assumed the unit had been fried by the lightning strike, even though the circuit breaker (differential type) cuts off in a matter of milliseconds.
Then suddenly I received an e-mail message from the server saying that it was up and running and in the process of re-synching. The re-synch completed successfully and the administrative interface showed everything as working properly. The shares on the NAS were all accessible from my Windows desktop as usual.
While I was in the administrative interface I decided to turn on the timed power-down feature, setting the NAS to power down at midnight and back up again at 7 AM. It powered down, but now it won't power up again. I've again pushed the power button several times, but with no luck.
Since the unit did behave absolutely normally during the period when it was powered up, I am assuming that the power supply is at fault again. I am now looking for a replacement (possibly the Seasonic SS-250SU). But I would like to get confirmation from anybody out there that the power supply really is the only problem. OR any suggestions people may have as to how to get it to power up. Could my turning on the automatic power-down feature have anything to do with the problem? OR whether the Seasonic PSU is a good option.
Thanks in advance to everyone

Yup. You can test that it turns on the supply with it disconnected before you do it with it connected. You'll know the supply came on because the fan will run.
If it works, you likely won't want to leave it that way, but it's a way to get the data off the NAS.

I don't think you'll be able to find the seasonic anymore.
There are a couple of options here:

Though the last two are quite expensive.
It's likely time to get a new NAS. You can jury-rig an ATX supply (running externally) to extract the data.
Support can also temporarily mount the data volume (Read-only) in a new ReadyNAS - though they will charge.
It does sound like it could be a problem with the +5VSB (5V standby) power that powers the power-on circuit and NIC.
Thanks! So you think a PSU replacement would put me back in business? As I said, the unit seems to work fine once it's powered up. Plus, as I mentioned above, a new NAS would be expensive for me.
Thanks for replying! Actually I found a PSU in the UK (I'm in France) for around 65£, and it's made specifically for the NV+. When you say it's time to replace the NAS, are you saying it because you assume other components may be or may go bad, or just because PSUs are expensive? I looked around and it looks like I'd have to pay at least 350€ for a new one.

It's an old NAS - so other components will fail at some point (and may have already failed along with the PSU). It's not fully compatible with Windows 10 (since it is limited to SMB 1.0) and that will become more of a bother over time. Plus it is slow by current standards.
It's true that a new NAS would cost quite a bit more than the PSU. But at some point you'll need to get a new one (since yours is 8 years old).
My own NV+ is about the same age - it is still in service as a secondary backup. It is on it's second PSU (which luckily failed right before the warranty was up). When it fails I'll just take it out of service.
Okay, I opened the case and tested the power supply, and all voltages are in line with the specs. So it looks like it's not the PSU after all.
I removed the top cover (exposing the memory slot) and sniffed and there is a slight burned smell. So I suppose some other component could be bad. But it seems odd that the unit did started up and stayed on line long enough to complete a re-synch.
I'm open to any suggestions.
Thanks for your answer.
<<Did you test it under load?>>
Uh, no. How do I do that? All I have is a cheap multimeter. I pulled the mainboard connector, jumped pins 14 and 15, and tested each pin as per the pinout diagram.
