I have this system and a Seasonic M12II Evo 750w. First, i though that my system will shut down because my PSU was not enough. My system doesn't shuted down even while gaming underload but i think it's pushing his limits while is underload. The fan is so loud and this is not normal. Should i change to Cooler Master v850 +80 GOLD CERTIFIED to avoid any problem or damage in my system? Also i see that my frame rate in some games is not good and maybe is my PSU. Is that posible? My PSY is causing damage and drops in FPS of my games? Pls help me!!
