Apex shutting off PC

@Darkness93_ytHey there! From the information im finding online on nvidia forums and such most these cases appear to be PSU related with this card specifically. So it very well may not be enough power for the pc and the card it self which would explain why it can handle your lower end card. Only options I can think of is trouble shooting the PSU to run on rails for testing. I would have to guess it just is not strong enough for your set up. Is your PSU 750+ watts?

If its not happening on other games this still would not indicate the PSU is strong enough. It just means that game is not as resource heavy as apex is.
