I have an MSI 980 Ti Armour 2X graphics card and a 500W power supply that is 80+ certified. I know that this power supply is too small, but would this cause the card to overheat? I got up to 91C with 5 case fans while playing a game.... I have an i5 7500 processor. Neither the cpu or gpu have overclocks except for the factory overclock on the gpu.
