About a month ago i had my computer built and everything seemed to running pretty smoothly. Whenever I would put it under load, (gaming/rendering videos), it would be completely fine. Just a few days ago I installed a Hyper 212 Evo and now whenever my computer is put under load it shuts down within 5-10 min. Nothing is overheating because my CPU temps are about 45c-50c when gaming and gpu temps are about 65c-70c. I can browse internet just fine and play simple games like Minecraft or Hearthstone, but when I play something that requires my computer to be pushed slightly it will shut down after about 5 min of gameplay. Im not sure whether this is a PSU thing or what, but if anyone has a suggestion on what I could do that would be much appreciated.
