I recently got a new GTX 660 GPU and i'm having a problem where my computer will completely shut off when i play graphically taxing games such as skyrim and assassins creed black flag. When i play other games like minecraft it will run fine and never crash the computer and it will run around 60fps. To test it out i installed shaders which made it much more taxing on the gpu and crashed after about an hour of playing. After i loaded it again it crashed only seconds into it. With skyrim and assassins creed it crashes seconds into playing. I've looked online for people with similar problems and i think that the issue might be my power supply which is CORSAIR CX CX500 500W ATX12V v2.3 80 PLUS BRONZE. I'm stuck however and don't know for sure if this is the problem since with research i've heard so many different things about the PSU's. The minimum for the card is 450W and on another post about a similar problem some of the comments insisted he should have at least a 700W. This video here made me think that my PSU isn't the problem at all: . While this other video made me think i probably should get around a 700-750W PSU: . If any one can help id really appreciate it!
Added (1). Another thing to note is that i tryed my card in my buddies computer and he has a 600W +80 bronze and the card ran perfectly fine for about half an hour on skyrim. Also my heat when it crashes is like 40-50 C.
