RNDX4000 doesn't power on anymore

Solved.

I received zero replies to my post, peraphs it was a too stupid question for all of you or peraphs none was interested.

Any case thanks to all guys read my question.

I have connected the NAS to a PSU from an old PC I had at home.

The NAS is now 100% working, so the NAS didn't power-on because the original PSU "Seventeam ST-220FUB-5E" was fault.

Here it's how I solved, hoping it could help anyone has an out-of-warranty Netgear NAS that do not power-on anymore and wants to check if the troubles are caused by a defective PSU using a zero-cost old ATX PSU.

As the RNDX4000 uses a modified ATX power connector, before to connect the PSU ATX 20-pin cable to the NAS, I have modified the PSU pinout as showed in document ReadyNAS_PSU_pinout.pdf, by removing the two –12V(Blue) and –5V(White) cables and replacing these with two +5V cables I found in a 12V 4-pin power connector that is also available on the PC ATX.

A lot of video tutiorial show how to remove the molex connector from the 20-pin ATX port.

Unfortunately the replacing PSU do not fit the NAS case, but for me this a little problem.
