AX860i Possible problem with PSU on Shutdown


Recommended Posts

Hey guys,


I have no luck in finding other people with the same problem as me, so I hope someone can help me with this issue.


I have a Corsair AX860i PSU that i used for about a year now. I recently took it out of my old computer with an AMD CPU on an Asus Crosshair IV formula MB and put it in my new one.

Since then i am hearing these clicking sounds coming out of my PSU 2-3 seconds after my computer has shut down.

There are almost always 4 loud clicks, which kinda sound like a relay switch.


My new build has a Haswell CPU on an Asus Maximus VI Hero MB, and it seems to be normal that the PSU switches power from the +5VSB to the normal +5V between the off and on modes. But i understand that is on shutdown and mostly just 1 click.

However this issue occurs 2-3 seconds after shutdown with 4 clicks.


I just wanted to know if there is a problem with my PSU and if so, could it harm the rest of my computer?

So it didn't do this with the old build and only does it with the new one?


I never heard of this before. But there could be something on that board's +5VSB that is making the +5V load switch back and forth more than just once.

This started happening in the new build, it didn't do this in my old one.

My computer is running without other problems, so i can't pin this on any other component atm. My Asus Hero MB has newer features then my 3-year old Crosshair IV tho, so maybe it has something to do with that.
