All,

I have replaced the PSU in my sons N50-640 with a Corsair RM650 using a 24 to 6 pin adapter for the mobo and the other standard 8 pin PSU connected for the 12v. It all runs and works well. however when you turn it off, the computer dies down but the case fan keeps running and there is power still to the USB's so everything he has plugged in like speakers and USB charger etc… stay powered.

What am I missing? how do I fix this?

    Those 24 to 6 pin adapter cables is where the problem is, as these Acer proprietary mainboard and PSU desktops are not meant to be upgraded with a 24 pin PSU. You need to study the 24 pin to the 6 pin orientation of the mainboard and PSU 24 pins and orient the new PSU to supply voltage the same way in the same pin numbers like below to the board. I can only give you the oem pins of these plugs as documented by Acer for the N50-640 desktop, hope that helps you out. Good luck.

    This is the plugs tat you need to check on the N50-640
