[Help] EPU setting disabled or enabled

What's up guys. New to overclocking just over clocked my amd fx 8350 from 4.0 to 4.3ghz, volt is 1.40. I woke this morning and my keyboard was on with my pc off, read some forums that suggest the epu needs to be changed, so I did it and the keyboard is off but my question is, is it safe with the overclock?
Amd 8350
Asus m5a99fx r pro 2.0
8g ram
750w psu
Corsair h100i cooling

Any help would be greatly appreciated.

Do you have a switch on the motherboard you can select either TPU or EPU? Select TPU. Won't mess with your overclock but may help you get a higher overclock.
