Im not sure if im posting in the right section.

i actually have a RGB 850W psu.

recently i change my case and the case have fan with led light installed.

After the case change, the psu ring led is not working. The psu is working fine and the fan is working but the light is not working even if i press the buttton.


I have 2 monitor installed and R9 370 gpu.

when i restart the pc and unplug my second monitor, the psu light is working. Not sure what is the problem with it.

Sometime i dont have to unplug the monitor but i need to restart the pc for the psu led ring to be working.
