I recently purchased two new case fans for my pc and after installing them my pc is now randomly restarting whilst playing games. My first guess would be my psu is not powerfull enough as I have a 750 watt power supply for my pc which has a i7 6700k , an asus k3 gaming motherboard, 2 sticks of vengence 4gb ram and another 2 sticks of vengence 8gb ram, the msi r9 390x and my 5 case fans, i also have 1, 2 and 3 terabyte hard drives all running on the 750 watt psu.

Looking at my specs I would think it is the psu but I just wanted to make sure before I purchase a 850 or 1000 watt one.

Thanks
