Dead RN316
I have a RN316 (6 bay) that stopped working (not powering up) - it's EOL. I'd like to replace the PSU to determine if that is the reason or if it's the MB. The exiting PSU is a DPS-200PB-186A (...
Yes, the modifications to the 20-pin connector for the legacy NAS are the same as for the native OS6 ones. You should be able to confirm that based on the colors of the wires in your old one. Most of the later ones do need the 4-pin CPU power connector, so that supply won't work with those since it lacks one. But since the 316 doesn't need it, it should work fine.

The 316 only has 20 pin connector for the MB, the 4 pin connector is not needed so I'll use those +12V wires for it.
The NAS powers up fine with the new PSU. I just wanted to ensure when I connect the +12V wires it doesn't blow anything up 🙂
I found this, however it does not specifically state it can be used for the RN300 / 316 series ReadyNAS:

Is the diagram on the right (under "ReadyNAS NV, NV+ and 1100 use modified ATX power connector") also applicable for the RN316? (based on your description, it appears to also apply to the RN316)
The PDF shows that on the 20 pin connector, PIN 12 (-12V BLUE) changes to a +12V YELLOW wire as you described, and PIN 18 (-5V WHITE) changes to a +12V YELLOW wire as you also described.
