ReadyNAS Business Pro Power Supply Replacement
Earlier this year my ReadyNAS got double booted in a very short period of time following a power outage that lasted longer than my backup. Afterwards it appeared the PS was dead. I did diligent res...
I did more searching and found a prevous link where I brought up the PS issue: https://community.netgear.com/t5/ReadyNAS-Hardware-Compatibility/NVX-Business-Edition-RNDX4210-won-t-power-on/m-p/1313191#M16175
In that link it was suggested I buy the PS from Europe and the replacement on that link looks similar to the Kentek it was suggested I buy, but neither of those two supplies are similar to the one I took out, not would they fit in my case.
Seems there is some confusion here on what PS goes in what case, and that might be the source for the problem of getting the wrong PS suggested. I have a RNDP6350 Business Pro. It is a squarish PS with a fan covering most of one side which faces the back of the NAS and a modified AC connector to allow for a different switch mounting, with the PS's own switch left to ON. Here is a picture showing what I was told to buy and the one I took out for comparison. Having watched some videos and read more, it appears along the line the PS style was changed. Don't assume you are being told the right information for a replacement, pull it out and check and then compare it to what is being reccomended.
Anyone want to buy a new Kentek PS at a discount :(
The post you referenced is for replacing the supply in an NVX, a 4-bay legacy system. Your 6-bay Pro takes an entirely different form factor, wiring, and wattage.
You need an SFX form factor power supply with at least 300W. The Seasonic is recommended if you can get one (it is apparently hard to get in some European countries). You must not change the wiring as is listed for the 4-bay supply in the reference message, but you will need a 6-inch standard 24-pin ATX extension. You may want to transfer the 90° Molex connectors from the old supply to the new to reduce the wire length for those connections and make installation a little cleaner.
Happens the Seasonic SS-300SFD is readily available and I sure wish I had looked at what I had before ordering the wrong PS.
The new Seasonic PS, like you mentioned, has different wiring. I mistakenly bought a 20-pin power extension so I am considering just splicing in wire to extend the ATX connector.
The new PS has three drive power connectors. Two have the double 4-pin Molex with the smaller style 4-pin connector on the end, like for floppies. The third power cable has a pair of SATA power connectors instead. Assuming no wiring changes were done like with the other NAS, I think I can get from A to Z.
Thanks.
No changes to the pin-out on this one. I've done three now, and I always cut down the wires for the 4-pin and SATA drives and move the 90° Molex connectors to them just to make the install cleaner. But using 3 of the existing Molex connectors and shoehorning the wiring in works fine, just be careful not to let the fan hit anything. If you decide to go with the extension instead of adding wire, you can clip off the side clips designed for chassis mounting and it will lay flat between the motherboard and case. I normally use aluminum duct tape to close off the holes left by removing the harness retention device and double-sticky tape down the connector, but that's not really necessary, either.
Thanks for the info..... I was reading elsewhere that some people were having a problem with a delayed start. I was wondering if mine was just having a delayed started or if in fact the PS or something is bad. So I installed the original PS back in but even when I wait, it is just dead. No sign of life. Turns out I had ordered a 20-pin ATX PS extension so I am sending it back and have a 24-pin one coming. I am going to try and hook it up outside the case to see if it gets the system to turn on. I am so nervous something other than the PS is bad.
I made a mistake and didn't pay much attention to the two ten-pin connections that you need to disconnect to get the PS connector and RAM out. I am hoping they only go back one way, with the shorter one going on top and the longer one going on the bottom?
I also read about people having issues due to an old or dead MOBO battery, the CR2032, so I also replaced that. I am about ready to rest the system with the new PS connected outside the case, but I hope I hear from someone that the 10-pin connectors connect as I expected them to.
I also saw a write-up about the CPU fan being incorrectly connected to the mobo instead of to the IO card. This article tells you to move the CPU fan to the io card.

However, the CPU fan cable is 4-connector, and it is being moved to a 3-connector jack? I am sure the 4-pin connector will plug into the 3-pin connector, but it means one of the fan wires won't be connected? Has anyone done this change? If it allows the CPU fan to run slower, it will extend it's life and reduce system noise. Did you make this change too? Thanks sir!
