Hello,

If I turn off my computer (shutdown via windows or power button, doesn't matter), and then leave it for some time (not sure the minimum but it is usually over night), I cannot actually turn it back on. I have a mouse plugged in and after even it being off the light on the mouse continues to be lit.

I can turn it back on instantly without issues, but if it is over night I have to switch off the power on the button on my PSU, wait about 40 second for the light to turn off on my mouse (and I presume so there is no more power going around my PSU).

It's really annoying and only started happening when I put in my new PSU (Corsair CX600)
Thanks
