Hi.. I had an electrician visiting for something in my home, and needed to turn off power in house.. So I ssh'ed into my readynas and shut it down, and then I went and pulled the main power switch...

I agree with StephenB , it sounds like a power supply issue. While the ReadyNAS are built well, they tend to be used much longer than a typical desktop PC, so the power supplies just wear out.
Yes, a standard ATX12V power supply will work externally and make recovering the volume much easier. If you already have one around, it's also the best way to see if that's really the problem, But since you have to run the cords through a gap in the chassis and the original PSU fan is no longer running, you should cover the PSU fan (but not the main one) and any gaps around the cables with making tape or similar if you are running it for any duration other than to just see it now works. The NAS uses the 24-pin ATX connector, square 4-pin CPU power connector, and three 4-pin Molex (old HD type) connectors. You may need a SATA to Molex adapter or Y-cable to have enough Molex connectors.
The supply itself is an SFX format one, and not really all that hard to replace. But you will normally need an extender for the 24-pin connector and possibly the Molex adapter or Y cable I mentioned earlier.. While the original is a 300W supply, I recommend at least a 350W one because the original has more 12V than a typical 300W. Some SFX supplies have an offset fan and, while I have not done so myself, reports here have been that they work OK. If purchasing on eBay, use care in ordering an SFX supply -- look at the pictures and dimensions. I've seen supplies listed as "SFX" that clearly are not and will not work in a ReadyNAS.

Thanks for the reply.. It looks cramped in the tower, so replacing the PSU seems tedious.. But guess I'll start of seeing if I can dig up a PSU with compatible connectors I can just hook up to it without putting it in, and see if I can blow any life into it then.. I've got a linux box I can try to hook them into if all else fails, though I guess I likely need a extra diskcontroller if I should manage that..

Have been delaying this for quite a while, as I didn't look forward to try and get the PSU out and hoping to find another PSU to test with, but now I've plucked out the original Seasonic one and ordered an be quiet! SFX Power 2 400W 80 Plus Bronze PSU. Hoping that should fix my issue. If not, I guess I'll try to get a PCI card with enough SATA connectors and try to mount the disks elsewhere..
Will reply once I find out.. Though sadly gotta wait for SFX PSU that had to be ordered by store so guess it can take a while. Thanks a lot for the input ;)- humbe76Dec 21, 2021Aspirant
Failed to find someone close having a spare PSU to test, so ended up ordering a new SFX PSU, but then shop was out of stock, so I had to order a bigger one and now I've finally got that one. Cooler Master V Series V550 SFX 550W 80 PLUS Gold so probably a bit overkill for the box, but hopefully stable at least ;)
Finally I've verified that it was the PSU, and I can now boot up the box again and access files ;D
The new PSU had the power outlet on the other side though, so using the special 3 small cables to connect to the power outlet on the box looked tricky, but thankfully they were just long enough that it was still possible. Dunno how I coulda gotten longer cables like that.. But then I found that the cable with 24 pin power to the motherboard was too short too.. So currently booted box up with PSU sitting on top of an open case :/..
Have ordered some extension cords for the 24 pin power cable and hope that works out, so I'll finally get out of the woods ;)
Thanks for the feedback all..- SandsharkDec 22, 2021Sensei - Experienced User
Yes, the 24-pin extension is required for just about any supply you use, save ones that have been modified for ReadyNAS use. Many also need 4-pin Molex Y cables and/or SATA to Molex adapters unless you want to re-wire using the 90° connectors from the old one (which is what I do).
But I'm glad it was the supply. It's one of few replaceable parts. The supply is often the first thing to go. It's not that they aren't made well, it's that most just hold on to their NAS a lot longer than the supplies were designed for. That says a lot for the part Negear builds themselves.
