Old ReadyNAS comes back from the dead - Very weird
I could not enter the model because the system didn't have it listed. It's an old ReadyNAS Pro Business. More than three months ago, in September, the unit died. It was functioning as an rsync ba...

Just search eBay for "readynas pro power supply". Then make sure you don't mistakenly select one for a Pro4.

Bad capacitors can heal themselves (an internal short finally blows open like a fuse), though it doesn't usually last for very long. The most likely place is the power supply. The fact that it started on it's own may point to the 5VSB (5 volt standby) output of the power supply, which powers the on/off circuit and is also always on unless the switch on the back is off or the unit is unplugged. But the unit will also come on on it's own if mains power is cycled, so it could be something else in the supply.
As for a replacement, you need an SFX format one. Though the original is 300W, I recommend at least 350 for the replacement since the original has more 12V current than most 300W. Higher current is also fine, though adds to cost. You are going to need an extender for the 24-pin connector, which is a standard PC ATX one. Most need about 5", but you may want to wait till you get the supply to measure yourself. You'll also need three 4-pin Molex connectors (old-style hard drive power connectors). Most supplies made today don't have that, so you'll need at least one Y cable and/or SATA to Molex adapter unless your replacement supply is cabled such that you can move the 90° Molex connectors from the old to the new (which I like to do, because I can also trim the cable length).
There is an eBay vendor who sells SFX suppies already modified for the 6-bay legacy ReadyNAS if you want to take the easy (and not that much more expensive) way. I've not tried them, and have no affiliation, but others have reported success with them.

Thank you for this great information. I feel reasonably comfortable taking things apart and putting them back together, but I'm not familiar with the cables and connectors you've mentioned. I've been looking through the vendor's items on ebay and am still unsure exactly which unit to get (and any additional items I might need). Would you feel comfortable providing the name of the vendor you mentioned and the specific item(s) I will need? (If you don't want to mention a vendor here you could probably PM me.)
Given that a new NAS is into the 4 digit cost category, I don't mind paying for a more turn-key solution for this replacement power supply.
Again, thanks for much for your help.

Sandshark sensei (definitely a sensei), thank you so much for this additional information. I didn't even think that a search using readynas pro as keywords would yield any result. (Clearly, my mistake.)
I plan to order the power supply and get this old NAS up and running. Maybe I'll even get some new larger drives for it. Because of its vintage the Legacy list of compatible drives maxes out at 4TB, but I expect that larger NAS compatible ones will probably be OK. And, if they're not I can put them into my other NAS.
Again, thanks so much for providing great information.

A processor upgrade will add a lot to an older Pro BE or Pioneer. They have a Pentium Dual E2160 @ 1.80GHz and the board can (with the latest BIOS) accept a Core2 Duo E7500 @ 2.93GHz, which is quite cheap on eBay these days. It'll accept the 7600 as well, but those are harder to find. The newer Pro6 has a Pentium Dual E5300 @ 2.60GHz, so the upgrade isn't as significant.
Just be sure to do the bios upgrade before you do the processor swap, or it won't boot.
