So I have a 560ti and when im playing subnautica or high stress skyrim it will crash and displays nothing, and it wont turn back on until restarted. I believe the issue is that the powersupply I have (non branded) 450 watt psu has only 24 amps on the 12 volt rail. Is there any other issue that could be causing this? The temps never hit over 71c.
